Dr. Jason Fung
Dr. Jason Fung

Dr. Jason Fung is a Canadian nephrologist. He’s a world-leading expert on intermittent fasting and low carb, especially for treating people with type 2 diabetes. He has written three best-selling health books and he co-founded the Intensive Dietary Management program.

TLDR: Main takeaways

  • Insulin drives weight-gain
  • Reduce your consumption of added sugars
  • Reduce your consumption of refined grains
  • Moderate your protein consumption
  • Increase your consumption of natural fats
  • Increase your consumption of fiber and vinegar
  • Use intermittent fasting
  • A lot of todays nutritional “truths” are based on very little or shaky scientific backing

Notes on The Obesity Code

The art of medicine is quite peculiar. Once in a while, medical treatments become established that don’t really work. Through sheer inertia, these treatments get handed down from one generation of doctors to the next and survive for a surprisingly long time, despite their lack of effectiveness.

In the science of nutrition, there is rarely any consensus about anything:

  • Dietary fat is bad. No dietary fat is good. There are good fats and bad fats.
  • Carbohydrates are bad. No, carbohydrates are good. There are good carbs and bad carbs.
  • You should eat more meals a day. No, you should eat fewer meals a day.

Evidence-based medicine does not mean taking every piece of low-quality evidence at face value. I often read statements such as “low-fat diets proven to completely reverse heart disease.” The reference will be a study of five rats.

The parable of the cow

Two cows were discussing the latest nutritional research, which had been done on lions. One cow says to the other, “Did you hear that we’ve been wrong these last 200 years? The latest research shows that eating grass is bad for you and eating meat is good.” So the two cows began eating meat. Shortly afterward, they got sick and died.

Causal factors vs association studies

It is dangerous to assume that because two factors are associated, one is the cause of the other. Witness the hormone replacement therapy disaster in post-menopausal women. Hormone replacement therapy was associated with lower heart disease, but that did not mean that it was the cause of lower heart disease. However, in nutritional research, it is not always possible to avoid association studies, as they are often the best available evidence.

Of all the parasites that affect humanity, I do not know of, nor can I imagine, any more distressing than that of obesity

Fat doctors

Here’s the question that has always bothered me: Why are there doctors who are fat? Accepted as authorities in human physiology, doctors should be true experts on the causes and treatments of obesity. Most doctors are also very hardworking and self-diciplined. Since nobody wants to be fat, doctors in particular should have both the knowledge and the dedication to stay thin and healthy. So why are there fat doctors?
The standard prescription for weight loss is “Eat less, move more.” It sounds perfectly reasonable, but why doesn’t it work?

The demonization of dietary fat

The increase in life expectancy from 1900 to 1950 reinforced the perception of a coronary disease epidemic. For a white male, the life expectancy in 1900 was fifty years. By 1950, it had reached sixty-six years, and by 1970, almost sixty-eight years. If people were not dying of tuberculosis, then they would live long enough to develop their heart attack. Currently, the average age at first heart attack is sixty-six years. The risk of a heart attack in a fifty-year-old man is substantially lower than in a sixty-eight-year-old man. So the natural consequence of a longer life expectancy is an increased rate of coronary disease.

But all great stories need a villain, and dietary fat was cast into that role. Dietary fat was thought to increase the amount of cholesterol, a fatty substance that is thought to contribute to heart disease, in the blood. Soon, physicians began to advocate lower-fat diets. With great enthusiasm and shaky science, the demonization of dietary fat began in earnest.

There was a problem, though we didn’t see it at the time. The three macronutrients are fat, protein and carbohydrates: lowering dietary fat meant replacing it with either protein or carbohydrates. Since many high-protein foods like meat and dairy are also high in fat, it is difficult to lower fat in the diet without lowering protein as well.

So, if one were to restrict dietary fats, then one must increase dietary carbohydrates and vice versa. In the developed world, these carbohydrates all tend to be highly refined. Low fat = high carbohydrate.

This dilemma created significant cognitive dissonance. Refined carbohydrates coult not be simultaneously be both good (because they are low in fat) and bad (because they are fattening). The solution adopted by most nutrition experts was to suggest that carbohydrates were no longer fattening. Instead, calories were fattening. Without evidence or historical precedent, it was arbitrarily decided that excess calories caused weight gain, not specific foods. Fat, as the dietary villain, was now deemed fattening – a previously unknown concept. The calories-in/calories-out model began to displace the prevailing “fattening carbohydrates” model.

The issue was finally settled in 1977, not by scientific debate and discovery, but by governmental decree. George McGovern, then chairman of the United States Senate Select Committee on Nutrition and Human Needs, convened a tribunal, and after several days of deliberation, it was decided that henceforth, dietary fat was guilty as charged. Not only was dietary fat guilty of causing heart disease, but it also caused obesity, since fat is calorically dense.

The resulting declaration became the Dietary Goals for the United States. An entire nation, and soon the entire world, would now follow nutritional advice from a politician. This was a remarkable break from tradition. For the first time, a government institution intruded into the kitchens of America. Mom used to tell us what we should and should not eat. But from now on Big Brother would be telling us. And he said, “Eat less fat and more carbohydrates.”

The food pyramid

The Dietary Guidelines for Americans, now updated every five years, spawned the infamous food pyramid in all its counterfactual glory. The foods that formed the base of the pyramid – the foods we should eat every single day – were breads, pastas and potatoes. These were the prceise foods that we had previously avoided to stay thin. For example, the American Heart Association’s 1995 pamphlet, The American Heart Association Diet: An Eating Plan for Healthy Americans, declared we should eat six or more servings of “breads, cereals, pasta and starchy vegetables that are low in fat and cholesterol.” To drink, “Choose fruit punches, carbonated soft drinks.” Ahhh. White bread and carbonated soft drinks – the dinner of champions. Thank you, American Heart Association.

Success!

Refined grain consumption increased by almost 45 percent. Since carbohydrates in North America tended to be refined, we ate more and more low-fat bread and pasta, not cauliflower and kale.
Success! From 1976 to 1996, the average

  • fat intake increased from 45 percent of calories to 35 percent
  • Butter consumption decreased 38 percent
  • Animal protein decreased 13 percent
  • Egg consumption decreased 18 percent
  • Grains and sugars increased

There is no survival advantage to carrying a very high body-fat percentage. A male marathon runner may have 5 to 11 percent body fat. This amount provides enough energy to survive for more than a month without eating.

Is a calorie a calorie?

“A calorie is a calorie” implies that the only important variable in weight gain is the total caloric intake, and thus, all foods can be reduced to their caloric energy. But does a calorie of olive oil cause the same metabolic response as a calorie of sugar? The answer is, obviously, no. These two foods have many easily measurable differences. Sugar will increase the blood glucose level and provoke an insulin response from the pancreas. Olive oil will not. When olive oil is absorbed by the small intestine and transported to the liver, there is no significant increase in blood glucose or insulin. The two foods evoke vastly different metabolic and hormonal responses.

How do we process food?

What is a calorie? A calorie is simply a unit of energy. Different foods are burned in a laboratory, and the amount of heat released is measured to determine a caloric value for that food. All the foods we eat contain calories. Food first enters the somach, where it is mixed with stomach acid and slowly released into the small intestine. Nutrients are extracted throughout the journey through the small and large intestines. What remains is excreted as stool. Proteins are broken down into their building blocks, amino acids. These are used to build and repair the body’s tissues, and the excess is stored. Fats are directly absorbed into the body. Carbohydrates are broken down into their building blocks, sugars. Proteins, fats and carbohydrates all provide caloric energy for the body, but differ greatly in their metabolic processing. This results in different hormonal stimuli.

Caloric reduction is not the primary factor in weight loss

The correlation between weight gain and the increase in calorie consumption has recently broken down. Data from the National Health and Nutrition Examination Survey in the United States from 1990 to 2010 finds no association between increased calorie consumption and weight gain. While obesity increased at a rate of 0.37 percent per year, caloric intake remained virtually stable. Women slightly increased their average daily intake from 1761 to 1781, but men slightly decreased theirs from 2616 to 2511.

If we eat an extra 200 calories today, nothing prevents the body from burning that excess for heat. Or perhaps that extra 200 calories is excreted as stool. Or perhaps the liver uses the extra 200. We obsess about caloric input into the system, but output is far more important.

Reducing calories in works only if calories out remains stable. What we find instead is that a sudden reduction of calories in causes a similar reduction in calories out, and no weight is lost as the body balances its energy budget. Some historic experiments in calorie reduction have shown exactly this.

(In this experiment) thirty-six young, healthy, normal men were selected. For the first three months, subjects received a standard diet of 3200 calories per day. Over the next six months of semi-starvation, only 1570 calories were given to them. However, caloric intake was continually adjusted to reach a target total weight loss of 24 percent, averaging 1.1 kg per week. Some eventually received less than 1000 calories per day.

Even (the professor initiating the study) was shocked by the difficulty of the experiment. The men experienced profound physical and psychological changes. Among the most consistent findings was the constant feeling of cold experience by the participants.
Resting metabolic rate dropped by 40 percent. Measurement of the subjects strength showed a 21 percent decrease. Heart rate slowed considerably, from an average of fifty-five beats per minute to only thirty-five. Heart stroke volume decreased by 20 percent. Body temperature dropped to 35.4 degrees. Physical endurance dropped by half. Blood pressure dropped. Men became extremely tired and dizzy. They lost hair and their nails grew brittle. Psychologically, there were equally devastating effects. The men experienced a complete lack of interest in everything except for food.

The body reacts in this way – by reducing energy expenditure – because the body is smart and doesn’t want to die. What would happen if the body continued to expend 3000 calories daily while taking in only 1500? Soon fat stores would be burned, then protein stores would be burned, and then you would die. Nice. The smart course of action for the body is to immediately reduce caloric expenditure to 1500 calories per day to restore balance. Caloric expenditure may even be adjusted a little lower to create a margin of safety. This is exactly what the body does.

With reflection, it should immediately be obvious that caloric expenditure must decrease. If we reduce daily calorie intake by 500 calories, we assume that 0.45 kg of fat per week is lost. Does that mean that in 200 weeks, we would lose 91 kg and weigh zero kg? Of course not. The body must, at some point, reduce its caloric expenditure to meet the lower caloric intake.

Doctor’s orders

The applicability of these findings to caloric-reduction diets is obvious. Assume that prior to dieting, a woman eats and burns 2000 calories per day. Following doctor’s orders, she adopts a calorie-restricted portion-controlled, low-fat diet, reducing her intake by 500 calories per day. She feels lousy, tired, cold, hungry, irritable and depressed, but sticks with it, thinking that things must eventually improve. Initially, she loses weight, but as her body’s caloric expenditure decreases to match her lowered intake, her weight plateaus. Her dietary compliance is good, but one year later, things have not improved. Her weight slowly creeps back up, even though she eats the same number of calories. Tired of feeling so lousy, she abandons the failed diet and resumes eating 2000 calories per day. Since her metabolism has slowed to an output of only 1500 calories per day, all her weight comes rushing back – as fat. Those around her silently accuse her of lacking willpower. Sound familiar? But her weight regain is not her failure. Instead, it’s to be expected. Everything described here has been well documented over the last 100 years!

Caloric reduction and portion-control strategies only make you tired and hungry. Worst of all, you regain all the weight you have lost.

Glycogen

Glycogen is easily available, but in limited supply. During a short-term fast, your body has enough glycogen available to function. During a prolonged fast, your body can make new glucose from its fat stores – a process called gluconeogenesis (the “making of new sugar”). Fat is burned to release energy, which is then sent out to the body – the fat-storage process in reverse.

This situation partially explains the difficulty in losing accumulated fat. Before getting money from the bank, you spend what’s in your wallet first. But you don’t like having an empty wallet. In the same manner, before getting energy from the Fat Bank, you spend the energy in the Glycogen Wallet. But you also don’t like an empty Glycogen Wallet. So you keep the Glycogen Wallet filled, which prevents you from accessing the Fat Bank. In other words, before you can even begin to burn fat, you start feeling hungry and anxious because your glycogen is becoming depleted. If you continually refill your glycogen stores, you never need to use you fat stores for energy.

Insulin

Under normal conditions, high insulin levels encourage sugar and fat storage. Low insulin levels encourage glycogen and fat burning. Sustained levels of excessive insulin will tend to increase fat storage. An imbalance between the feeding and fasting will lead to increased insulin, which causes increased fat, and voilà – obesity. Could insulin be the hormonal regulator of body weight?

Certainly, the insulin response differs greatly between lean and obese patients. Obese patients tend to have a higher fasting insulin level, as well as an exaggerated insulin response to food. It is possible that this hormonal activity leads to weight gain.

Insulin can make you fat

In a fascinating 1993 study, high-dose insulin allowed virtual normalization of blood sugars in a group of type 2 diabetic patients. Starting from zero, the dose was increased to an average of 100 units per day over a period of six months. At the same time, patients decreased their caloric intake by more than 300 calories per day.

The patients’ blood sugar levels were great. But what happened to their weight? It increased by an average of 8.7 kg! Despite eating less than ever, patients gained weight like crazy. It wasn’t calories that drove their weight gain. It was insulin.

Insulin can make you thin

If insulin causes weight gain, can lowering its levels have the opposite effect? Type 1 diabetes is an autoimmune disease that destroys the insulin-producing beta cells of the pancreas. Type 1 diabetes has been descibred since ancient times. Arataeus of Cappadocia, a renowned ancient Greek pysician, wrote this classic description: “Diabetes is a melting down of flesh and limbs into urine.” No matter how many calories the patient ingests, he or she cannot gain any weight. Until the discovery of insulin, this disease was almost universally fatal.

Insulin levels go waaayyy down. Patients lose a lot of weight. In the type 1 diabetic community, there is a disorder called “diabulimia.” Diabulimia is the deliberate under-dosing of insulin for the purpose of immediate and substantial weight loss. It is extremely dangerous and certainly not advisable. However, the practice persist because it is an extremely effective form of weight loss.

Insulin levels go down. Weight is lost.

The results are very consistent. Drugs that raise insulin levels cause weight gain. Drugs that have no effect on insulin levels are weight neutral. Drugs that lower insulin levels cause weight loss. The effect on weight is independent of the effect on blood sugar.

Hormones

Hormones tell us we are hungry (ghrelin). Hormones tell us we are full (peptide yy, cholecystokinin). Hormones increase energy expenditure (adrenalin). Hormones shut down energy expenditure (thyroid hormone). Obesity is a hormonal dysregulation of fat accumulation. Calories are nothing more than the proximate cause of obesity.

Obesity is a hormonal, not a caloric imbalance.

Both fasting insulin and fasting leptin levels are higher in obese people, indicating a state of both insulin and leptin resistance. The leptin response to a meal was also different. In lean people, leptin levels rose – which makes sense, as leptin is a satiety hormone. However, in obese subjects, leptin levels fell. Despite the meal, their brains were not getting the message to stop eating.

Understanding how to treat obesity

Once we understand that obesity is a hormonal imbalance, we can begin to treat it. If we believe that excess calories cause obesity, then the treatment is to reduce calories. But this method has been a complete failure. However, if too much insulin causes obesity, then it becomes clear we need to lower insulin levels.
The question is not how to balance calories; the question is how to balance our hormones. The most crucial question in obesity is how to reduce insulin.

Cortisol

Once released, cortisol substantially enhances glucose availability, which provides energy for muscles – very necessary in helping us to run and avoid being eaten. All available energy is directed toward surviving the stressful event. Growth, digestion and other long-term metabolic activities are temporarily restricted. Proteins are broken down and converted to glucose .

At first glance, cortisol and insulin appears to have opposite effects. Insulin is a storage hormone. Under high insulin levels (mealtimes), the body stores energy in the form of glycogen and fat. Cortisol, however, prepares the body for action, moving energy out of stores and into readily available forms, such as glucose. That cortisol and insulin would have similar weight-gain effects seems remarkable – but they do. With short-term physical stress, insulin and cortisol play opposite roles. Something quite different happens, though, when we’re under long-term psychological stress.

In our modern-day lives, we have many chronic, nonphysical stressors that increase our cortisol levels. For example, marital issues, problems at work, arguments with children and sleep deprivation are all serious stressors, but they do not result in the vigorous physical exertion needed to burn off the blood glucose. Under conditions of chronic stress, glucose levels remain high and there is no resolution to the stressor. Our blood glucose can remain elevated for months, triggering the release of insulin. Chronically elevated cortisol leads to increased insulin levels – as demonstrated by several studies.

And so, by extension, stress causes weight gain – something that many people have intuitively understood, despite the lack of rigourous evidence. Stress contains neither calories nor carbohydrates, but can still lead to obesity. Long-term stress leads to long-term elevated cortisol levels, which leads to extra pounds.

Sleep

Sleep deprivation is a major cause of chronic stress today. Sleep duration has been steadily declining. In 1910, people slept nine hours on average. However, recently, more than 30 percent of adults between the age of thirty and sixty-four report getting fewer than six hours of sleep per night. Shift workers are especially prone to sleep deprivation and often report fewer than five hours of sleep per night.

Population studies consistently link short sleep duration and excess weight, generally with seven hours being the point where weight gain starts. Sleeping five to six hours was associated with a more than 50 percent increased risk of weight gain. The more sleep deprivation, the more weight gained.

Getting enough sleep is essential to any weight loss plan.

The empire strikes back

The American Heart Association (AHA) published its own book called the No-Fad Diet: A personal Plan for Healthy Weight Loss. It’s only mildly ironic that while condemning other diets, the AHA would recommend the only diet (low-fat) repeatedly proven to fail. But the low-fat religion was enshrined in the medical community and it did not tolerate disbelievers.

No concern that higher intake of sugar and other refined carbohydrates could be harmful. No concern that the low-fat diet had been proved a spectacular failure by every dietary study done. No concern that obesity and diabetes epidemics were raging full force under their very noses. The AHA fiddled while Rome burned.

During the forty years that the AHA advised a low-fat diet, the obesity crisis grew to gargantuan proportions. Yet no time did the AHA question whether their completely ineffectual advice was actually helping people. Instead, doctors played their favorite game: blame the patient. It is not our fault the diet doesn’t work. It is their fault for not following the diet.

It is now increasingly recognized that the low-fat campaign has been based on little scientific evidence and may have caused unintended health consequences

Harvard researchers DRS. Frank Hu & Walter Willett, 2001

Cholesterol

The liver manufactures the overwhelming majority -80 percent- of the blood cholesterol, with only 20 percent coming from diet. Cholesterol is often portrayed as some harmful poisonous substance that must be eliminated, but nothing could be farther from the truth. Cholesterol is a key building block in the membranes that surround all the cells in our body. In fact, it’s so vital that every cell in the body except the brain has the ability to make it. If you reduce cholesterol in your diet, your body will simply make more.

Addictive food

Let us assume we’re at a all-you-can-eat buffet. At some point, you simply cannot eat any more, and the idea of consuming two more pork chops is sickening. That feeling is your satiety hormones telling you that you’ve had enough. But what if you were offered a small slice of cake or apple pie? Doesn’t seem so hard to eat now, does it? As kids, we used to call this the second-stomach phenomenon: after the first stomach for regular food was full, we imagined that there was a second one for desserts. Somehow, despite being full, we still have room for highly refined carbohudrates like cake and pie – but not proteins or fats. Highly refined and processed foods somehow do not trigger the release of satiety hormones, and we go ahead and eat cake.

Think about foods that people say they’re “addicted” to. Pasta, bread, cookies, chocolate, chips. Notice anything? All are highly refined carbohydrates. Does anybody ever say they are addicted to fish? Apples? Beef? Spinach? Not likely. Those are all delicious foods, but not addictive.

Refined carbohydrates are easy to become addicted to and overeat precisely because there are no natural satiety hormones for refined carbs. The reason is that refined carbohydrates are not natural foods but are instead highly processed. Their toxicity lies in that processing.

Unrefined carbohydrates are different

Dr Staffan Lindeberg studied the residents of Kitava, one of the Trobriand Islands in Papua New Guinea – one of the last places on earth where poeple ate a largely traditional diet. Starchy vegetables, including yam, sweet potato, taro and cassava, made up the basis of their diet. An estimated 69 percent of calories were derived from carbohydrates, and less than 1 percent of the calories came from processed Western foods.

Despite this high carbohydrate intake, insulin was very low among the Kitavans, resulting in virtually no obesity. Comparing the Kitavans to his native Swedish population, Dr. Lindeberg found that despite a diet that was 70 percent carbohydrates (unrefined), the Kitavans had insulin levels below the 5th percentile of Swedes. The body mass index of young Kitavans averaged 22 (normal) and it decreased with age.

Similarly, natives of the Japanese island of Okinawa eat a diet that is nearly 85 percent unrefined carbohydrates. The dietary staple is sweet potato. They eat three times as many green and yellow vegetables, but only 25 percent of the sugar consumed by residents of nearby Japan. Despite the high intake of carbohydrates, there is virtually no obesity, and the average body mass index is only 20.4. They are one of the longest-lived people in the world, with more than triple the rate (compared to nearby Japan) of people living past 100 years.

Homeostasis

In his 1945 Nobel lecture, “Penicillin,” Dr. Fleming correctly predicted the emergence of resistance:

“There is the danger that the ignorant man may easily underdose himself and by eposing his mocrobes to non lethal quantities of the drug make them resistant. Here is a hypothetical illustration: Mr. X has a sore throat. He buys some penicillin and gives himself, not enough to kill the streptococci but enough to educate them to resist penicillin.

By 1947, the first cases of antibiotic resistance were reported. How did Dr. Fleming so confidently predict this development? He understood homeostasis. Exposure causes resistance. A biological system that becomes disturbed tries to go back to its original state. As we use an antibiotic more and more, organisms resistant to it are naturally selected to survive and reproduce. Eventually, these resistant organisms dominate, and the antibiotic becomes useless.

(…) even using normal, physiologic levels of insulin will yield the exact same result. Men with no previous history of obesity, pre-diabetes or diabetes were given a ninety-six-hour constant intravenous infusion of insulin. By the end, their insulin sensitivity dropped by 20 percent to 40 percent. The implications are simply staggering. With normal but persistent amounts of insulin alone, these healthy, young, lean men can be made insulin resistant. I can start these men on the road to diabetes and obesity simply by administering insulin – which causes insulin resistance.

The main compartments are the brain, liver and muscle. Changing the resistance of one does not change resistance in the others. For example, hepatic (liver) insulin resistance does not affect insulin resistance in the brain or muscle. When we ingest excess carbohydrates, we develop hepatic insulin resistance. Significant dietary intervention will reverse the hepatic insulin resistance, but will have no effect on insulin resistance in the muscles or the brain. Lack of exercise may lead to insulin resistance in the muscles. Exercise will increase insulin sensitivity there, but has little effect on insulin resistance in the liver or brain.

Whenever the body is exposed to a constant stimulus, it acclimates to it

When we eat

In the development of obesity, the increase in meals is almost twice as important as the change in diet. We obsess about what we should eat, all in the hopes of making us slim. But we spare not even a single thought as to when we should be eating.

Eating six small meals per day causes the metabolic rate to go up six times a day, but only a little.

One myth is that eating frequently keeps blood glucose from becoming too low. But unless you have diabetes, your blood sugars are stable whether you eat six times a day or six times a month.

We are eating all the time. Societal norms, which had previously frowned upon eating except at mealtimes, now permit eating anywhere, anytime. Government agencies and schools actively encourage snacking, something that previously had been heavily discouraged. We are taught to eat the minute we roll out of bed. We are taught to eat throughout the day and eat again just before sleep. We spend up to eighteen hours in the insulin-dominant state, with only six hours insulin deficient.

Crazier still – we have been brainwashed to believe that constant eating is somehow good for us! Not just acceptable, but healthy.

Indeed, many health professionals have been very vocal about increasing the number of eating occasions. This situation is just as crazy as it sounds. Eat more to weigh less. That doesn’t even sound like it will work. And guess what? It doesn’t.

Big Food

Big Food sponsors many large nutritional organizations. And then there are the medical associations. In 1988, the American Heart Association decided that it would be a good idea to start accepting cash to put its Heart Check symbol on foods of otherwise dubious nutritional quality. The Center for Science in the Public Interest estimates that in 2002, the AHA received over $2 million from this program alone. Food companies paid $7500 for one to nine products, but there was a volume discount for more than twenty-five products! Exclusive deals were, of course, more expensive. In 2009, nutritional standouts such as Cocoa Puffs and Frosted Mini Wheats were still on the Heart Check list.

Funding sources

Funding sources have enormous influence on study results. In a 2007 study that looked specifically on soft drinks, Dr. David Ludwig from Harvard University found that accepting funds from companies whose products are reviewed increased the likelihood of a favorable result by approximately 700 percent!

The scapegoat: Calories

The obesity epidemic couldn’t very well be ignored, and a culprit had to be found. “Calories” was the perfect scapegoat. Eat fewer calories, they said. But eat more of everything else. There is no company that sells “Calories,” nor is there a brand called “Calories.” There is no food called “Calories.” Nameless and faceless, calories were the ideal stooge. “Calories” could now take all the blame. They say candy doesn’t make you fat. Calories does. They say that 100 calories of cola is just as likely as 100 calories of broccoli to make you fat. They say that a calorie is a calorie. But show me a single person that grew fat by eating too much steamed broccoli. I know it. You know it.

One of the worst myths is that eating more frequently causes weight loss. Eat snacks to lose weight? It sounds pretty stupid. And it is.

Obesity has begun to afflict younger and younger children. In one study covering a twenty-two-year period ending in 2001, children of all ages show an increased prevalence of obesity, even in the zero- to six-month-old age range. That finding is especially interesting. Conventional calorie-based theories of obesity are unable to explain this trend. Obesity is considered an energy-balance problem, one of eating too much and exercising too little. Since six month-olds eat on demand and are often breastfed, it is impossible that they eat too much. Since they do not walk, it is impossible that they exercise too little. Similarly, birth weight has increased by as much as 200 grams over the last twenty-five years. The newborn cannot eat too much or exercise too little. What is going on here?

The sad but inescapable conclusion is that we are now passing on our obesity to our children. Why? Because we are now marinating our children in insulin starting in the womb, they develop more severe obesity sooner than ever before. Because obesity is time dependent and gets worse, fat babies become fat children. Fat children become fat adults. And fat adults have fat babies in turn, passing obesity on to the next generation.

Several large-scale studies on prevention of childhood obesity were started in the late 1990s. (…) The specific nutritional goal was to reduce dietary fat to less than 30 percent (…) Did the children learn how to eat a low-fat diet? Sure did. Dietary fat started at 34 percent of calories and over the course of the study, fell to 27 percent. Did they eat fewer calories? Sure did. The intervention group averaged 1892 calories per day compared to 2157 calories per day in the control group. Fantastic! The children were eating 265 fewer calories per day. They learned their lessons extremely well, eating fewer calories and less fat overall. Over the course of three years, calorie counters expected a loss of approximately 37 kilograms! But did the children’s weight actually change? Not even by a little bit. It was the “largest school-based randomized trial ever conducted.” They ate less and exercised more. They just didn’t lose any weight.

Calories do not drive weight gain, and thus reducing them will not lead to weight loss.

Knowing that they were fighting a losing battle in North America and Europe, the sugar pushers took aim at Asia to make up for lost profits. Asian sugar consumption is rising at almost 5 percent per year. Things are shocking when you consider that only 1 percent of Chinese had type 2 diabetes in 1980. In a single generation, the diabetes rate rose by a horrifying 1160 percent. Sugar, more than any other refined carbohydrate, seems to be particularly fattening and leads to type 2 diabetes.

Diabetes correlates with sugar, not calories.

Breakfast

The majority of Americans identify breakfast as the most important meal of the day. Eating a hearty breakfast is considered a cornerstone of a healthy diet. Skipping it, we are told, will make us ravenously hungry and prone to overeat for the rest of the day. Although we think it’s a universal truth, it’s really only a North American custom. Many people in France (a famously skinny nation) drink coffee in the morning and skip breakfast.

It is simply not necessary to eat the minute we wake up. We imagine the need to “fuel up” for the day ahead. However, our body has already done that automatically. Every morning, just before we wake up, a natural circadian rhythm jolts our bodies with a heady mix of growth hormone, cortisol, epinephrine and adrenalin. This cocktail stimulates the liver to make new glucose, essentially giving us a shot of the good stuff to wake us up. This effect is called the dawn phenomenon, and it has been well described for decades.

Many people are not hungry in the morning. The natural cortisol and adrenalin released stimulates a mild flight-or-fight response, which activates the sympathetic nervous system.

Our bodies are gearing up for action in the morning, not for eating.

All these hormones release glucose into the blood for quick energy. We’re already gassed up and ready to go. There is simply no need to refuel with sugary cereals and bagels. Morning hunger is often a behavior learned over decades, starting in childhood.

A large breakfast is thought to reduce food intake throughout the rest of the day. However, such does not always seem to be the case. Studies show that lunch and dinner portions tend to stay constant, regardless of the amount of calories taken at breakfast. The more one eats at breakfast, the higher the total caloric intake over the entire day. Worse, taking breakfast increases the number of eating opportunities in a day. Breakfast eaters therefore tend to eat more and eat more often – a deadly combination.

Furthermore, many people confess that they are not hungry first thing in the morning and force themselves to eat only because they feel that doing so is the healthy choice. As ridiculous as it sounds, many people force themselves to eat more in an effort to lose weight.

(In a study) breakfast eaters averaged 539 extra calories per day compared to those that skipped breakfast – a finding consistent with other trials.

Breakfast is the most important meal of the day – for Big Food. Sensing the perfect opportunity to sell more highly profitable, highly processed “breakfast” foods, Big Food circled the easy money like sharks on wounded prey. “Eat breakfast!” they thundered. “It’s the most important meal of the day!” they bellowed. Even better, here was an opportunity to “educate” the doctors, dieticians and other medical professionals. Those people had a respectability Big Food could never achieve. So the money flowed.

There are some commonsense questions you can ask yourself about breakfast. Are you hungry at breakfast? If not, listen to your body and don’t eat. Does breakfast make you hungry? If you eat a slice of toast and drink a glass of orange juice in the morning – are you hungry an hour later? If so, don’t eat breakfast. If you are hungry and want to eat breakfast, then do so. But avoid sugars and refined carbohydrates. Skipping breakfast does not give you the freedom to eat a Krispy Kreme donut as a mid-morning snack either.

Our own disaster

Our own disastrous, misguided dietary changes since the 1970s have created the diabesity debacle. We have seen the enemy, and it is ourselves. Eat more carbohydrates. Eat more often. Eat breakfast. Eat more. Ironically, these dietary changes were prescribed to reduce heart disease, but instead, we’ve encouraged it since diabesity is one of the strongest risk factors for heart disease and stroke. We’ve been trying to put out a fire with gasoline.

Government policies

Despite the similarity in culture and genetics between populations in Canada and the United States, U.S rates of obesity are much higher. This fact suggests that government policies must play a role in the development of obesity.

Socioeconomic status has long been known to play a role in development of obesity in that poverty correlates very closely with obesity. States with the most poverty also tend to have the most obesity.

Financial aid

While mass production of corn and wheat receives generous support, the same cannot be said for cabbage, broccoli, apples, strawberries, spinach, lettuce and blueberries. Food additives receive almost thirty times more in subsidies. Saddest of all, apples receive the most, not the least, federal aid of all fruits and vegetables. All other receive negligible support.

Was this a giant conspiracy to keep us sick? Doubtful. The large subsidies were simply the result of programs to make food affordable, which began in the 1970s. Back then, the major health concern was not obesity, but heart disease that was believed to be the result of excess dietary fat. The base of the Food Pyramid, the foods to be eaten by us every day, was bread, pasta, potatoes and rice. Naturally, money flowed into subsidies for those foods, the production of which was encouraged by the U.S Department of Agriculture. Refined grains and corn products soon became affordable by all. Obesity followed like the grim reaper.

It is noteworthy that, in the 1920s, sugar was relatively expensive. A 1930 study showed that type 2 diabetes was far more common among the wealthier northern states compared to the poorer southern states. As sugar became extremely cheap, however, this relationship inverted. Now, poverty is associated with type 2 diabetes, rather than the other way around.

The second-stomach phenomenon

Removing protein and fat in the diet may lead to overconsumption. There are natural satiety hormones (peptide YY, cholecystokinin) that respond to protein and fat. Eating pure carbohydrate does not activate these systems and leads to overconsumption (the second-stomach phenomenon).

Nutritionism

A big problem was the inadvertent triumph of nutritionism. Rather than discussing individual foods (spinach, beef, ice cream), nutritionism reduced foods to only three macronutrients: carbohydrates, proteins and fats. They were then subdivided further as saturated and unsaturated fats, trans fats, simple and complex carbohydrates, etc. This sort of simplistic analysis does not capture the hundreds of nutrients and phytochemicals in foods, all of which affect our metabolism. Nutritionism ingnores the complexity of food science and human biology.

An avocado, for instance, is not simply 88 percent fat, 16 percent carbohydrate and 5 percent protein with 4.9 grams of fiber. This sort of nutritional reductionism is how avocadoes became classified for decades as a “bad” food due to their high fat content, only to be reclassified today as a “super food”. Nutritionally, a piece of butterscotch candy cannot be reasonably compared to kale simply because both contain equal amounts of carbohydrate.

Nutritionally, a teaspoon of trans-fat-laden margarine cannot be reasonably compared to an avocado simply because both contain equal amounts of fats.

Smarter than nature

We gave our children artificial baby formula. We drank artificially sweetened sodas. We thought we were smarter than Mother Nature. Whatever she had made, we could make better. Out with all-natural butter. In with industrially produced, artificially colored trans-fat-laden margarine! Out with natural animal fats. In with solvent-extracted, bleached and deodorized vegetable oil! What could possibly go wrong?

Fats

Saturated fats are so named because they are saturated with hydrogen. This makes them chemically stable. The polyunsaturated fats, like most vegetable oils, have “holes” where the hydrogen is “missing.” They are less stable chemically, so they have a tendency to go rancid and have a short shelf life. The solution was to create artificial trans fats.

Ironically, trans-fat-laden margarines had always branded themselves as heart healthy since they were low in saturated fat. Twenty-year follow-up data from the Framingham study revealed that margarine consumption was associated with more heart attacks. By contrast, eating more butter was associated with fewer heart attacks.

A comprehensive review of all the studies of high-fat dairy finds no association with obesity, with whole milk, sour cream and cheese offering greater benefits than low-fat dairy.

Eating fat does not make you fat, but may protect you against it

Eating fat together with other foods tends to decrease glucose and insulin spikes. If anything, dietary fat would be expected to protect against obesity.

While literally thousands of papers have reviewed this data, perhaps Dr. Walter Willett of the Harvard T.H. Chan School of Public Health said it best in his 2002 review article entitled, “Dietary Fat Plays a Major Role in Obesity: No.” Considered one of the world’s foremost experts in nutrition, he writes: “Diets high in fat do not account for the high prevalence of excess body fat in Western countries; reduction in the percentage of energy from fat will have no important benefits and could further exacerbate this problem. The emphasis on total fat reduction has been a serious distraction in efforts to control obesity and improve health in general.

The multifactorial nature of obesity

The multifactorial nature of obesity is the crucial missing link. There is no one single cause of obesity. Do calories cause obesity? Yes, partially. Do carbohydrates cause obesity? Yes, partially. Does fiber protect us from obesity? Yes, partially. Does insulin resistance cause obesity? Yes, partially. Does sugar cause obesity? Yes, partially. All these factors converge on several hormonal pathways that lead to weight gain, and insulin is the most important of these. Low-carbohydrate diets reduce insulin. Low-calorie diets restrict all foods and therefore reduce insulin. Paleo and LCHF diets (low in refined and processed foods) reduce insulin. Reduced-food-reward diets reduce insulin.

The truth is that there are multiple overlapping pathways that lead to obesity. The common uniting theme is the hormonal imbalance of hyper-insulinemia. For some patients, sugar or refined carbohydrates are the main problem. Low-carbohydrate diets may work best here. For others, the main problem may be insulin resistance. Changing meal timing or intermittent fasting may be the most beneficial. For others, the cortisol pathway is domimant. Stress reduction techniques or correcting sleep deprivation may be critical. Lack of fiber may be the critical factor for yet others.

Most diets attack one part of the problem at a time. But why? In cancer treatment, for example, multiple types of chemotherapy and radiation are combined together. The probability of success is much higher with a broad-based attack. In cardiovascular disease, multiple drug treatments work together. Treating high blood pressure does not mean ignoring smoking.

In cardiovascular disease, for example, “Choose the treatment that suits you” would never be considered satisfactory advice.

It is also important to tailor the approach individually to address the cause of the high insulin levels. For example, if chronic sleep deprivation is the main problem causing weight gain, then decreasing refined grains is not likely to help. If excessive sugar intake is the problem, then mindfulness meditation is not going to be especially helpful.

Obesity is a hormonal disorder of fat regulation. Insulin is the major hormone that drives weight gain, so the rational therapy is to lower insulin levels.

The steps to lower insulin levels

  • Reduce your consumption of added sugars
  • Reduce your consumption of refined grains
  • Moderate your protein consumption
  • Increase your consumption of natural fats
  • Increase your consumption of fiber and vinegar

Coffee

Coffee, even the decaffeinated version, appears to protect against type 2 diabetes. In a 2009 review, each additional daily cup of coffee lowered the risk of diabetes by 7 percent, even up to six cups per day. The European Protective Investigation into Cancer and Nutrition study estimated that drinking at least three cups of coffee or tea daily reduced the risk of diabetes by 42 percent. The Singapore Chinese Health Study showed a 30 percent reduction in risk.

Coffee drinking is associated with a 10 to 15 percent reduction in total mortality. Large-scale studies found that most major causes of death, including heart disease were reduced. Coffee may guard against the neurologic diseases Alzheimer’s, Parkinson’s disease, liver cirrhosis and liver cancer.

A word of caution here: While these correlation studies are suggestive, they are not proof of benefit. However, they suggest that coffee may not be as harmful as we imagined.

Vinegar

Vinegar is also a protective factor. Used in many traditional foods, it may help reduce insulin spikes. Italians often eat bread dipped in oil and vinegar – a prime example of eating a high-carb food with protective factors. Vinegar is added to sushi rice, which reduces its glycemic index by 20 to 40 percent.

Fasting

While we obsess over the question of what to eat, we virtually ignore the crucial aspect of meal timing

To succeed, we must break the insulin-resistance cycle. But how? The body’s knee-jerk reaction to insulin resistance is to increase insulin levels, which, in turn, creates even more resistance. To break the cycle, we must have recurring periods of very low insulin levels.

We know that eating the proper foods prevents high levels, but it won’t do much to lower them. Some foods are better than others; nonetheless, all foods increase insulin production. If all foods raise insulin, then the only way for us to lower it is to completely abstain from food. The answer we are looking for, is fasting.

The ancient Greeks believed that medical treatment could be discovered by observing nature. Humans, like most animals, do not eat when they become sick. Consider the last time you were sick with the flu. Probably the last thing you wanted to was eat. Fasting seems to be a universal human response to multiple forms of illnesses and is ingrained in human heritage, as old as mankind itself. Fasting is, in a sense, an instinct.

The ancient Greeks believed that fasting improved cognitive abilities. Think about the last time you ate a huge Thanksgiving meal. Did you feel more energetic and mentally alert afterward? Or instead, did you feel sleepy and a little dopey? More likely the latter. Blood is shunted to your digestive system to cope with the huge influx of food, leaving less blood for brain function. Fasting does the opposite, leaving more blood for your brain.

The body’s response to fasting

Glucose and fat are the body’s main sources of energy. When glucose is not available, then the body adjusts by using fat, without any health detriment. This compensation is a natural part of life. Periodic food scarcity has always been part of human history, and our bodies have evolved processes to deal with this fact of Paleolithic life. The transition from the fed state to the fasted state occurs in several stages.

  • Feeding: During meals, insulin levels are raised. This allows glucose uptake by tissues such as the muscle or brain for direct use as energy. Excess glucose is stored as glycogen in the liver.
  • The post-absorptive phase (six to twenty-four hours after fasting starts): Insulin levels begin to fall. The breakdown of glycogen releases glucose for energy. Glycogen stores last for roughly twenty-four hours.
  • Gluconeogenesis (twenty-four hours to two days): The liver manufactures new glucose from amino acids and glycerol. In non-diabetic persons, glucose levels fall but stay within the normal range.
  • Ketosis (one to three days after fasting starts): The storage form of fat, triglycerides, is broken into the glycerol backbone and three fatty acid chains. Glycerol is used for gluconeogenesis. Fatty acids may be used directly for energy by many tissues in the body, but not the brain. Ketone bodies, capable of crossing the blood-brain barrier, are produced from fatty acids for use by the brain. Ketones can supply up to 75 percent of the energy used by the brain.
  • Protein conservation phase (after five days): High levels of growth hormone maintain muscle mass and lean tissues. The energy for maintenance of basal metabolism is almost entirely met by the use of free fatty acids and ketones. Increased adrenalin levels prevent the decrease in the metabolic rate.

The human body is well adapted for dealing with the absence of food. Stored food (fat) is naturally released to fill the void. The body does not “burn muscle” in an effort to feed itself until all the fat stores are used. It’s crucial to note that alle these beneficial adaptive changes do not occur in the caloric-reduction diet strategy.

Regular fasting, by routinely lowering insulin levels, has been shown to significantly improve insulin sensitivity. This finding is the missing piece in the weight-loss puzzle.

Growth hormone

Growth hormone is known to increase the availability and utility of fats for fuel. It also helps to preserve muscle mass and bone density. Growth hormone secretion is difficult to measure accurately because of its intermittent release, but it decreases steadily with age. One of the most potent stimuli to growth hormone secretion is fasting. Over a five-day fasting period, growth hormone secretion more than doubles. The net physiological effect is to maintain muscle mass and bone tissue mass during the fasting period.

Myths about fasting

Many myths have been repeated so often that they are often perceived as infallible truths.

  • Fasting will make you lose muscle/burn protein
  • The brain needs glucose to function
  • Fasting puts you in starvation mode/lowers basal metabolism
  • Fasting will overwhelm you with hunger
  • Fasting causes overeating when you resume feeding
  • Fasting deprives the body of nutrients
  • Fasting causes hypoglycemia
  • It’s just crazy

If these myths were true, none of us would be alive today. Think about the consequences of burning muscle for energy.

Starvation mode

Starvation mode is the mysterious bogeyman always raised to scare us away from missing even a single meal. This is simply absurd. Breakdown of muscle tissue happens only at extremely low levels of body fat -approximately 4 percent- which is not something most people need to worry about. At this point, there is no further body fat to be mobilized for energy, and lean tissue is consumed. Fat is burned first.

This situation is akin to storing a huge amount of firewood but deciding to burn your sofa instead. It’s stupid. Why do we assume the human body is so stupid?

There is another persistent myth that brain cells require glucose for proper functioning. This is incorrect. Human brains, unique among animals, can use ketones as a major fuel source during prolonged starvation, allowing the conservation of protein such as skeletal muscle. Again, consider the consequences if glucose were absolutely necessary for survival: humans just wouldn’t survive. After twenty-four hours, glucose becomes depleted. If our brains had no alternative, we would become blubbering idiots as our brains shut down. Our intellect, our only advantage against wild animals, would begin to disappear. Fat is the body’s way of storing food energy for the long term; it uses glucose/glycogen for the short term.

Daily caloric restriction does, in fact, lead to decreased metabolism, so people assumed that this effect would be magnified as food intake dropped to zero. It won’t. Decreasing food intake is matched by decreased energy expenditure. However, as food intake goes to zero, the body switches energy inputs from food to stored food (fat). This strategy significantly increases the availability of “food,” which is matched by an increase in energy expenditure.

Appetite tends to decrease with increased duration of fasting

Can I exercise while fasting?

There is no reason to stop your exercise routine during fasting. There is a common misconception that eating is necessary to supply “energy” to the working body. That’s not true. The liver supplies energy via gluconeogenesis. During longer fasting periods, the muscles are able to use fatty acids directly for energy.

Joy on demand: Notes

Main takeaways:
Be happy. Wish for others to be happy. Smile. Meditate. The world is a beautiful place.

Notes

Bicep curls for the mind

In my long struggle with misery, quite by accident, I discovered the mental equivalent of physical exercise. I found that one can deliberately effect life-changing mental changes with simple training exercises – if you will, bicep curls for the mind. And in doing so, improve every single aspect of our lives. The mental equivalent of physical exercise is meditation.

The lucky sperm club

I was born into a family that was poor but caring. In my entire life, I always had enough to eat (and I know my mom sometimes went hungry to ensure that). I always had shelter. I never suffered a single day of war nor a single day of homelessness. Despite being born in what was then a poor, developing country, my country had always given me clean water on tap, free vaccinations, and free education. Billionaire Warren Buffet famously referred to those who grow up in prosperity as “members of the lucky sperm club,” and given the circumstances of my birth and growing up, I too consider myself a member of that club. There are many millions of people who are born into circumstances in which they do not even have access to books, much less to education or clean water. If you are reading this book, it is likely that you are blessed with at least the same luck as I.

Willingness

The willingness to bear witness to our own pain and failure. To be willing an able to clearly see this self – this wretched useless self – to see all his pain, to see all his failings, his desperate clinging on to all things pleasant and his frenzied aversion to all things unpleasant, to see all the suffering involved in having this human form manifest in him, to be willing and able to bear witness to all of that with composure and kindness – that is an immense source of confidence.

Internal science

When (he) was becoming accomplished as a meditation teacher, he developed a conviction, which I totally agree with, that if meditation (which he calls “the internal science and technology of the east”) were to successfully mate with the science and technology of the west, it will change the world dramatically, for the better.

Prepare for opportunities

A way I prepare for opportunities is by constantly prioritizing my personal growth, sometimes with spectacular results. In early 2000, when I was looking for a job, it was the height of the dot-com boom, and anybody with a pulse and a software engineering degree could get a job in Silicon Valley. Being an award-winning software engineer with straight A’s from a top university, I could have any job I wanted. I decided to join a small, unprofitable startup with a silly name called Google. Why? Because I decided I never want to be the smartest person in the room. If I am the smartest person in the room, I won’t learn anything. Hence, to maximize my personal growth, I chose to work in a company where people seemed to be much smarter than I, and it was Google. And, boy, did that decision work out.

In life, opportunity knocks fairly often, but if you are unprepared for it or unwilling to jump at it, then it will pass you by.

Familiarization

Familiarization is a key aspect of meditation. It’s so important that the Tibetan word for meditation literally means “to become familiar”. The more the mind is in contact with any mental quality (such as calm or joy), the more familiar it becomes with it, and the more familiar the mind becomes with that mental quality the more quickly and easily it gets it.

Meditation is not about not thinking

One of the biggest misconceptions about meditation is that it involves “emptying your mind of all thoughts.” This one misconception is more responsible for turning people away from meditation than any other that I know of. Many beginners mistakenly think that they are supposed to have no thoughts during meditation, and then when they find thought after thought cascading endlessly and uncontrollably in the mind like a raging waterfall, they decide that meditation is impossible and they give up.
No, meditation is not about suppressing thoughts. Instead, it is about allowing the mind to settle on its own terms, in its own time, which includes allowing thoughts to arise as and when they want to. It is true that over time, with practice, as the mind becomes more deeply settled, the stream of thoughts slows down and eventually goes from being a raging waterfall to being like a fast-flowing river, then more like a slow-flowing stream, and finally, the mind is like a placid lake.

One way to rest the mind is to use an image. Imagine a butterfly resting gently on a flower moving slowly in the breeze. In the same way, the mind rests gently on the breath. Another way is to use this mantra, “There is nowhere to go and nothing to do for this one moment, except to rest.”

To feel regretful, you need to be in the past, and to worry, you need to be in the future. Hence, when you are fully in the present, you are temporarily free from regret and worry.

Notice joy

The training is simple. It is simply to notice joy. Whenever there is any joy arising in our field of experience, even if it is merely a subtle hint of joy, simply notice that there is joy, that is all. That is the entire practice.

Noticing joy is like noticing blue cars on the road. When you’re in traffic, blue cars pass you by all the time and, usually, you don’t notice them at all. But if you play a game of noticing blue cars, you’ll find that they are everywhere. There is joy to be found in many moments of our lives, though it may be subtle and fleeting. For example, with that pleasant feeling of warm water on the skin as we get into the shower, joy arises immediately, but we seldom notice it and it fades away in seconds. The practice is simply to notice when joy is there.

Given this insight, we can effectively invite joy just by smiling a genuine smile. Smile as if you are really happy. When you do this, you may create changes in the autonomic nervous system relating to happiness, and from these changes, you may experience joy. This works for me almost every time. It doesn’t need to be a full smile – a half smile works as well.

Whenever there is any experience of joy, notice it. That is all.

Attending to the joy of pleasant daily experiences

Whenever you engage in an activity that involves a pleasant experience, take at least one moment to attend fully to the joy that pleasantness invokes. Some examples:

  • At each meal, attend fully to the enjoyment of at least the first bite
  • When seeing a loved one, take one moment to appreciate that he or she is there, and attend fully to that joy
  • When holding hands with a loved one, take one moment to attend fully to the joy of that contact

Keeping a gratitude journal, finding new things to be grateful for, and recalling a joyful experience every day are all great ideas. However, taking one moment to fully attend to every joyful experience has the advantage of taking no time and no effort. You can do it many times a day, in real time, with zero delay in gratification.

Some examples:

  • That promotion I got is so precious – I know because I worked years for it
  • Owning my car and my house are both precious, and I know because I saved up for years for my house and my car
  • Having a child who loves me is so precious – I know many people who do not
  • Having good health is so precious
  • Having a good livelihood is so precious
  • Living in a peaceful country is so precious
  • Having access to clean water and food is so precious
  • Being able to see the blue sky and green grass is so precious

Everything is amazing right now, and nobody’s happy

Louis C. K.

Awareness of mortality

Someday, I will die. Every single person I love will die, some of them before I do. Even if science and technology can extend the human lifespan to some extent, eventually, I will die, and everybody I love will die. Being aware of mortality changes everything. At the very least, it puts things into proper perspective, it gives us clarity into what is really important versus what is not so important, and it therefore changes how we prioritize things in our lives.

Just note gone

There is a simple practice that can greatly enhance your ability to notice the absence of pain, though it isn’t only concerned with pain. “Just note gone” is a powerful way of practicing with any phenomenon, whereby we train the mind to notice that something previously experienced is no more. For example, at the end of a breath, notice that the breath is over. Gone. As a sound fades away, notice when it is over. Gone. At the end of a thought, notice that the thought is over. Gone. At the end of an experience of emotion – joy, anger, sadness, or anything else – notice it is over. Gone.

This practice changes the way we perceive phenomena: It brings balance to our perception of sensory and mental events. Every sensory and mental event has three parts: arising, presence, and ceasing. Most of us are aware of the first two, but we are seldom aware of ceasing. In other words, our experience of sensory and mental events is unbalanced – we often see the coming but seldom the going. By noticing gone, you restore perceptual balance, thus moving toward seeing things as they really are.

Whatever is subject to origination is all subject to cessation

Wishing for random people to be happy

During working hours or school hours, randomly identify two people who walk past you or who are standing around you. Secretly wish for this person to be happy. Just think to yourself, “I wish for this person to be happy, and I wish for that person to be happy.” This is the entire practice. Don’t do anything; don’t say anything, just think.

Uplifting and settling the mind with altruistic joy

Setup
Sit in any posture that allows you to be alert and relaxed at the same time, whatever that means to you. You may keep your eyes open or closed.

Uplift the mind (2-5 minutes)
Take a few minutes to bring to mind one or more people to whom you have brought joy or benefit out of purely altruistic intent. Reflect on the deed(s). Take delight in your good intentions and deeds.

Settle the mind (5-10 minutes)
Settle the mind either with anchoring, resting, or being. You may anchor your attention to any sensory object such as the breath, or you may rest the mind on the breath like a butterfly resting gently on a flower, or you may simply sit without agenda. Allow the mind to settle on its own.

Closing (1-2 minutes)
Close by noticing if there is any joy present in the mind, and if so, attending to it for one or two minutes.

In addition to the formal practice, I also recommend the informal practice of taking a moment to rejoice in inner goodness and altruistic deeds whenever you see them.

Whenever you make a donation of time or labor, or do something out of altruistic intention, take a moment to think, “I am doing this out of altruistic intention. Having this intention makes me so happy.”

Whenever you meet or bring to mind an admirable, inspiring person, take a moment to think, “There exist this wonderful person in this world. I’m so happy.”

Whenever you see somebody performing an altruistic or heroic act, take a moment to think, “More good is being done in this world, I’m so happy.”

Just because you’re in pain doesn’t mean you can’t be joyful

Rigoberta was awarded the Nobel Peace Prize in 1992 for her life’s work in promoting human rights. When I met her, I found her to be exactly what you’d expect of a steriotypical Nobel Peace Prize winner: she was wise, kind, and joyful. She is friendly to everyone and treats everyone with kindness. She gives people a huge smile and warm hugs. She is bursting with joy. Right beneath the surface, however, there is a huge reservoir of pain. Her father was burned alive. Her mother was raped and tortured before she died. Her brother was murdered. She lost her youngest son. She watched many thousands of people oppressed, tortured, and murdered. When I realized the amount of pain she was holding, I wanted to cry. One of the signs of true greatness is the ability to hold a large amount of pain, not just with courage and equanimity, but also with kindness, compassion, and joy. Rigoberta showed me what greatness looks like. I was moved.

She showed me that when pain is overwhelming, joy does not dissolve away the pain. Instead, it becomes a skillful container for the pain, limiting its damage and allowing the healing process to work. It is a little like putting a cast around your leg when you have a serious fracture. It prevents further damage and allows the leg to heal over time. Rigoberta demonstrated to me, by her own example, how one can hold immense pain, gently, with joy.

Just because you’re in pain doesn’t mean you cannot be joyful

Peace prize nominee Dawn Engle

Seeing everything for the miracle it is

Zen master Thich Nhat Hanh poetically says, “The real miracle is not to walk on either water or in thin air, but to walk on earth. Every day we are engaged in a miracle which we don’t even recognize: a blue sky, white clouds, green leaves, the black, curious eyes of a child – our own two eyes. All is a miracle.”
Or, as Louis C. K. put it, less poetically but more humorously when he talked about people complaining on airplanes, “Did you partake in the miracle of human flight, you noncontributing zero? You got to fly! It’s amazing! Everybody on every plane should just constantly be going “Oh my god! Wow! You’re flying! You’re sitting in a chair, in the sky!”

A sailboat in the ocean

It is a parable of a person pushing a sailboat to the ocean. Before arriving at the ocean, the sailboat is pushed with much effort, but once it reaches the ocean, the sailboat is pushed with much effort, but once it reaches the ocean, pushing is useless. On the water, the sailboat is effortlessly propelled by the wind. The distance it travels on the ocean in one day is farther than it could be forced over land in a hundred years.

This analogy carries two important lessons. The first is that effortlessness often needs to be preceded by deliberate effort. If we never push the sailboat to the ocean, if instead we foolishly sit in the sailboat while it is on land hoping for it to be “propelled without effort by the wind,” we get nowhere. In meditation, effortlessness must be established on the foundation of attentional stability; otherwise it is really just mind wandering and a waste of your time. The second lesson is that while the effortful stage is important, its main role is to enable effortlessness. A meditator who does not understand this is like a sailor who keeps pushing the sailboat when it is already in the water, or worse, like the guy who pushes his sailboat all the way to the destination over land rather than pushing it to the water with the intent of sailing to the destination. He is wasting valuable time and effort. I’d rather be sailing.

It takes a very long time to be a overnight success

The non-self

As a fellow adventurer, I can share with you a description of the tiny bit of territory I have personally explored on this subject of non-self. It is nowhere near what the masters have described, but since my exploration is much closer to our day-to-day worldly experience, it may be helpful to you. In my exploration, I learned that there are at least two flavors of non-self, one weaker and one stronger. The weaker flavor is the experience that there is only the observer, and the observer has no identity. This flavor is actually quite easy to describe and fairly straightforward for someone with strong samatha and vipassana practice to arrive at. When we sleep, we sometimes dream. In our dreams, we are sometimes an entirely different person from the person in real life. In other words, in those dreams, we have an entirely different identity as the person who is awake. During the process of falling asleep and getting into that dream, the mind abandons one identity and takes on another. My experience of the first flavor of nonself took that path. Once, as I was in deep meditation, the mind became subtle enough to enter that dreamlike state while being vividly aware, and it arrived at the state after the mind abandons one identity but before the mind takes up another. In that state there was only the observer, and the observer had no identity whatsoever. There was no “Meng,” that “Meng” completely disappeared. There was only the observer. I was able to stay in that state for roughly thirty minutes, and that experience was life changing. In my life, some large percentage of my suffering arises from issues involving my identity (“How dare they treat me like this? Who do they take me for?” “Why am I not lovable?” “Why does he treat me like I am incompetent?”) When the observer has no identity, the observer gains experential realization that identity is entirely mind-made. Identity has no substance whatsoever – it is nothing but a mere creation of mind.

Having experienced that realization, when one gets back to real life, identity-related problems such as being treated like I’m useless or unimportant still sting, but the mind also knows that there is zero substance to that identity anyway, so the suffering is meaningfully reduced.

Strive hard to let go

In striving toward mastery in samantha, vipassana, and brahmavihara – calm-abiding, insight, and sublime states – what are we trying to achieve? Well, we are not trying to achieve anything at all. It is very important to understand that ultimately, meditation is not about getting anything – meditation is entirely about letting go. In fact, I can summerize my entire twenty-plus years of meditation practice in just two words: letting go. The entirety of my practice is learning to let go. For example, early on, I learned to let go of my addiction to constant sensory and mental stimulation. A bit later on, I learned to let go of restlessness and distraction during sitting meditation. Much later on, I learned to let go of some amount of greed, hatred, anxiety, and destructive ego. And at the current stage of my practice, I’m learning to let go of clinging, aversion, ill will, my dependence on sensory pleasure in general, and my need to fluff up my identity and ego. The entire process is nothing but letting go.

At every stage of letting go, I was rewarded with a new source of wholesome joy. For example, when I let go of the need to constantly be stimulated by some sensory pleasure, I experienced the joy of ease. I developed the ability to be joyful simply by sitting down and relaxing. When I let go of some meaningful amount of anger and resentment, I experienced the joy of goodwill. When I let go of my compulsion to not feel the unpleasant feelings relating to my failure, I experienced the joy of confidence. In every single case, what I experienced was the joy of freedom, for example, the joy of freedom from boredom, freedom from want, freedom from anxiety, freedom from my own ego, and freedom from resentment. I am, and always have been, enslaved by two tyrannical masters: my clinging to sensory and ego pleasures, and my aversion to all things unpleasant to senses and ego. I am the slave of Clinging Monster and Aversion Monster. With every bit more of letting go, I gain a little bit more freedom from this enslavement. In freedom, there is great joy.
