“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.”

“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.”

“Adult obesity and overweight statistics have increased by about 50 percent since the Dietary Goals were announced. [by the federal government, in 1977] That bears repeating: a 50 percent increase in obesity/overweight correlated with a 10 percent decrease in fat content in the diet.”

“So why is a third of our world battling obesity and spending huge sums to burn off excess calories, while the other two-thirds yearn to get more of them?”

“But humans have a built-in weakness for fats and sugar. We evolved in lean environments where it was a big plus for survival to gorge on calorie-dense foods whenever we found them. Whether or not they understand the biology, food marketers know the weakness and have exploited it without mercy. Obesity is generally viewed as a failure of personal resolve, with no acknowledgement of the genuine conspiracy in this historical scheme. People actually did sit in strategy meetings discussing ways to get all those surplus calories into people who neither needed nor wished to consume them. Children have been targeted especially; food companies spend over $10 billion a year selling food brands to kids, and it isn't broccoli they're pushing. Overweight children are a demographic in many ways similar to minors addicted to cigarettes, with one notable exception: their parents are usually their suppliers. We all subsidize the cheap calories with our tax dollars, the strategists make fortunes, and the overweight consumers get blamed for the violation. The perfect crime.”

“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?”
