“We don't get fat because we overeat; we overeat because we're getting fat”
― Gary Taubes, Why We Get Fat: And What to Do About It

“The simple answer as to why we get fat is that carbohydrates make us so; protein and fat do not”
― Gary Taubes, Why We Get Fat: And What to Do About It

“In other words, the science itself makes clear that hormones, enzymes, and growth factors regulate our fat tissue, just as they do everything else in the human body, and that we do not get fat because we overeat; we get fat because the carbohydrates in our diet make us fat. The science tells us that obesity is ultimately the result of a hormonal imbalance, not a caloric one—specifically, the stimulation of insulin secretion caused by eating easily digestible, carbohydrate-rich foods: refined carbohydrates, including flour and cereal grains, starchy vegetables such as potatoes, and sugars, like sucrose (table sugar) and high-fructose corn syrup. These carbohydrates literally make us fat, and by driving us to accumulate fat, they make us hungrier and they make us sedentary.
This is the fundamental reality of why we fatten, and if we’re to get lean and stay lean we’ll have to understand and accept it, and, perhaps more important, our doctors are going to have to understand and acknowledge it, too.”

“Of all the dangerous ideas that health officials could have embraced while trying to understand why we get fat, they would have been hard-pressed to find one ultimately more damaging than calories-in/calories-out. That it reinforces what appears to be so obvious - obesity as the penalty for gluttony and sloth - is what makes it so alluring. But it's misleading and misconceived on so many levels that it's hard to imagine how it survived unscathed and virtually unchallenged for the last fifty years.

It has done incalculable harm. Not only is this thinking at least partly responsible for the ever-growing numbers of obese and overweight in the world - while directing attention away from the real reasons we get fat - but it has served to reinforce the perception that those who get fat have no one to blame but themselves. That eating less invariably fails as a cure for obesity is rarely perceived as the single most important reason to make us question our assumptions, as Hilde Bruch suggested half a century ago. Rather, it is taken as still more evidence that the overweight and obese are incapable of following a diet and eating in moderation. And it put the blame for their physical condition squarely on their behavior, which couldn't be further from the truth.”

“The laboratory evidence that carbohydrate-rich diets can cause the body to reain water and so raise blood pressure, just as salt consumption is supposed to do, dates back well over a century”

“By 1991, for instance, epidemiologist surverys in populations had revealed that high cholesterol was NOT associated with heart disease or premature death in women. Rather, the higher the cholesterol in women, the longer they lived, a finding that was so consistent across populations and surveys that it prompted an editorial in the American Heart Associations journal, Circulation: "We are coming to realize," the three authors, led by UC San Francisco epidemiologist Stephen Hulley, wrote, "the the results of cardiovascular research in men, which represents the great majority of the effort thus far, may not apply to women.”

“…Sugar has become an ingredient avoidable in prepared and packaged foods only by concerted and determined effort, effectively ubiquitous. Not just in the obvious sweet foods (candy bars, cookies, ice creams, chocolates, sodas, juices, sports and energy drinks, sweetened iced tea, jams, jellies, and breakfast cereals both cold and hot), but also in peanut butter, salad dressings, ketchup, BBQ sauces, canned soups, cold cuts, luncheon meats, bacon, hot dogs, pretzels, chips, roasted peanuts, spaghetti sauces, canned tomatoes, and breads. From the 1980's onward manufacturers of products advertised as uniquely healthy because they were low in fat…not to mention gluten free, no MSG, and zero grams trans fat per serving, took to replacing those fat calories with sugar to make them equally…palatable and often disguising the sugar under one or more of the fifty plus names, by which the fructose-glucose combination of sugar and high-fructose corn syrup might be found. Fat was removed from candy bars sugar added, or at least kept, so that they became health food bars. Fat was removed from yogurts and sugars added and these became heart healthy snacks, breakfasts, and lunches.”

“The simplest way to look at all these associations, between obesity, heart disease, type 2 diabetes, metabolic syndrome, cancer, and Alzheimer's (not to mention the other the conditions that also associate with obesity and diabetes, such as gout, asthma, and fatty liver disease), is that what makes us fat - the quality and quantity of carbohydrates we consume - also makes us sick.”

“What sets science and the law apart from religion is that nothing is expected to be taken on faith. We're encouraged to ask whether the evidence actually supports what we're being told - or what we grew up believing - and we're allowed to ask whether we're hearing all the evidence or just some small prejudicial part of it. If our beliefs aren't supported by the evidence, then we're encouraged to alter our beliefs.”

“All diets that result in weight loss do so on one basis and one basis only: They reduce circulating levels of insulin; they create and prolong the negative stimulus of insulin deficiency.”
― Gary Taubes, The Case for Keto: The Truth About Low-Carb, High-Fat Eating

“Carbohydrate-rich foods—grains, starchy vegetables, and sugars—work to keep insulin elevated in our circulation, and that traps the fat we eat in our fat cells and inhibits the use of that fat for fuel. That’s what the obesity research community should have been trying rigorously to resolve or refute for the past sixty years.”

“No such ambiguity existed about sugar consumption. “We now eat in two weeks the amount of sugar our ancestors of 200 years ago ate in a whole year,â€� as the University of London nutritionist John Yudkin wrote in 1963 of the situation in England. “Sugar provides about 20 percent of our total intake of calories and nearly half of our carbohydrate.”

“It may be easier to believe that we remain lean because we're virtuous and we get fat because we're not, but the evidence simply says otherwise. Virtue has little more to with our weight than our height. When we grow taller, it's hormones and enzymes that are promoting growth, and we consume more calories than we expend as a result. Growth is the cause - increased appetite and decreased energy expenditure (gluttony and sloth) are the effects. When we grow fatter, the same is true as well.

We don't get fat because we overeat; we overeat because were fat.”
― Gary Taubes, Why We Get Fat: And What to Do About It

“What I tried to make clear in Good Calories, Bad Calories was that nutrition and obesity research lost its way after the Second World War with the evaporation of the European community of scientists and physicians that did pioneering work in those disciplines. It has since resisted all attempts to correct it. As a result, the individuals involved in this research have not only wasted decades of time, and effort, and money but have done incalculable damage along the way. Their beliefs have remained imperious to an ever-growing body of evidence that refutes them while being embraced by public-health authorities and translated into precisely the wrong advice about what to eat and, more important, what not to eat if we want to maintain a healthy weight and live a long and healthy life.”

“If the conventional thinking and advice worked, if eating less and exercising more were a meaningful solution to the problem of obesity and excess weight, we wouldn’t be here. If the true explanation for why we get fat were that we take in more calories than we expend and the excess is stored as fat, we wouldn’t be here.”
― Gary Taubes, The Case for Keto: The Truth About Low-Carb, High-Fat Eating

“Because the insulin level in the bloodstream is determined primarily by the carbohydrates that are consumed—their quantity and quality, as I’ll discuss—it’s those carbohydrates that ultimately determine how much fat we accumulate. Here’s the chain of events: 1.  You think about eating a meal containing carbohydrates. 2. You begin secreting insulin. 3. The insulin signals the fat cells to shut down the release of fatty acids (by inhibiting HSL) and take up more fatty acids (via LPL) from the circulation. 4. You start to get hungry, or hungrier. 5. You begin eating. 6. You secrete more insulin. 7. The carbohydrates are digested and enter the circulation as glucose, causing blood sugar levels to rise.§ 8. You secrete still more insulin. 9. Fat from the diet is stored as triglycerides in the fat cells, as are some of the carbohydrates that are converted into fat in the liver. 10.  The fat cells get fatter, and so do you. 11.  The fat stays in the fat cells until the insulin level drops. If”

“Looking at obesity without preconceived ideas,â€� she wrote, “one would assume that the main trend of research should be directed toward an examination of abnormalities of the fat metabolism, since by definition excessive accumulation of fat is the underlying abnormality. It so happens that this is the area in which the least work has been done.â€� She added, “As long as it was not known how the body builds up and breaks down its fat deposit, the ignorance was glossed over by simply stating that food taken in excess of body needs was stored and deposited in the fat cells, the way potatoes are put into a bag. Obviously, this is not so.”

“Astwood’s belief that those who fatten easily are fundamentally, physiologically and metabolically different from those who don’t. This implies that those of us who fatten easily can get fat on precisely the same food and even the same amount on which lean people stay lean. We can’t be told to eat like lean and healthy people eat and expect that advice to work, because we get fat eating like lean and healthy people. Indeed, we get fat and hungry eating like lean and healthy people do.”

“But if sedentary behavior makes us fat and physical activity prevents it, shouldn't the "exercise explosion" and the "new fitness revolution" have launched and epidemic of leanness rather than coinciding with an epidemic of obesity?”

“The most fattening foods are the ones that have the greatest effect on our blood sugar and insulin levels.”

“The point to keep in mind is that you don't lose fat because you cut calories; you lose fat because you cut out the foods that make you fat-the carbohydrates.”

“Carbohydrates are not required in a healthy human diet. Another way to say this (as proponents of carbohydrate restriction have) is that there is no such thing as an essential carbohydrate. Nutritionists will say that 120 to 130 grams of carbohydrates are required in a healthy diet, but this is because they confuse what the brain and central nervous system will burn for fuel when diets are carbohydrate richâ€�120 to 130 grams daily—with what we actually have to eat. If there are no carbohydrates in the diet, the brain and central nervous system will run on molecules called “ketones.â€� These are synthesized in the liver from the fat we eat and from fatty acids, mobilized from the fat tissue because we’re not eating carbohydrates and insulin levels are low, and even from some amino acids. With no carbohydrates in the diet, ketones will provide roughly three-quarters of the energy that our brains use. And this is why severely carbohydrate-restricted diets are known as “ketogenicâ€� diets. The rest of the energy required will come from glycerol, which is also being released from the fat tissue when the triglycerides are broken down into their component parts, and from glucose synthesized in the liver from the amino acids in protein. Because a diet that doesn’t include fattening carbohydrates will still include plenty of fat and protein, there will be no shortage of fuel for the brain.”

“Any diet can be made healthy or at least healthier—from vegan to meat-heavy—if the high-glycemic-index carbohydrates and sugars are removed, or reduced significantly.”

“Referring to obesity as a “form of malnutritionâ€� comes with no moral judgments attached, no belief system, no veiled insinuations of gluttony and sloth. It merely says that something is wrong with the food supply and it might behoove us to find out what.”

“Even if these researchers do see the need to address the problem immediately, though they have obligations and legitimate interests elsewhere, including being funded for other research. With luck, the ideas discussed in Good Calories, Bad Calories may be rigorously tested in the next twenty years. If confirmed, it will be another decade or so after that, at least, before our public health authorities actively change their official explanation for why we get fat, how that leads to illness, and what we have to do to avoid or reverse those fates. As I was told by a professor of nutrition at New York University after on of my lectures, the kind of change I'm advocating could take a lifetime to be accepted.”

“In 2007, Jeffrey Flier, dean of Harvard Medical School and his wife and colleague in obesity research, Terry Maratos-Flier, published an article in Scientific American called “What Fuels Fat.â€� In it, they described the intimate link between appetite and energy expenditure, making clear that they are not simply variables that an individual can consciously decide to change with the only effect being that his or her fat tissue will get smaller or larger to compensate. An animal whose food is suddenly restricted tends to reduce its energy expenditure both by being less active and by slowing energy use in cells, thereby limiting weight loss. It also experiences increased hunger so that once the restriction ends, it will eat more than its prior norm until the earlier weight is attained. What the Fliers accomplished in just two sentences is to explain why a hundred years of intuitively obvious dietary advice—eat less—doesn’t work in animals. If we restrict the amount of food an animal can eat (we can’t just tell it to eat less, we have to give it no choice), not only does it get hungry, but it actually expends less energy. Its metabolic rate slows down. Its cells burn less energy (because they have less energy to burn). And when it gets a chance to eat as much as it wants, it gains the weight right back. The”
