Science writer Gary Taubes has a knack for subverting conventional wisdom. Sixteen years ago, he published a groundbreaking feature article in The New York Times Magazine arguing that decades' worth of government-approved nutritional advice was flat-out wrong, ideologically motivated, and contributing to rising rates of obesity and diabetes. Traditional dieting guidance attacking fatty food and praising carbohydrates, he wrote, was based on "a big fat lie." – The Man Who Hated Carbs Before It Was Cool Of course Dr. Atkins had been saying essentially the same thing for 30 years before Taubes wrote his article for the NYT. But...

Those who love rib-eye steaks and double-cream Brie will feel better about their guilty pleasures after reading Nina Teicholz’s article in this weekend’s Wall Street Journal, “The Questionable Link Between Saturated Fat and Heart Disease.” She writes, for example: Too much whole-grain oatmeal for breakfast and whole-grain pasta for dinner, with fruit snacks in between, add up to a less healthy diet than one of eggs and bacon, followed by fish. Gary Taubes covered some of the same ground in his excellent 2008 book, Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health. Taubes argued...

A CALORIE is a calorie. This truism has been the foundation of nutritional wisdom and our beliefs about obesity since the 1960s. What it means is that a calorie of protein will generate the same energy when metabolized in a living organism as a calorie of fat or carbohydrate. When talking about obesity or why we get fat, evoking the phrase “a calorie is a calorie” is almost invariably used to imply that what we eat is relatively unimportant. We get fat because we take in more calories than we expend; we get lean if we do the opposite. Anyone...

"I've been preaching this since long before Gary Taubes' books came out. That's because I have a colleague who studies the physiology of insulin. From what I know, Taubes is right. A quote re Dietary Incorrectness at Powerline:...Taubes disputes the connection between dietary fat and high cholesterol. He challenges the thesis that dietary fat is detrimental to our health. He rejects a balanced diet. He advocates a high-fat diet. He opposes dieting. He doesn’t object to exercise, but he asserts that it makes you hungry. It’s almost funny. He is the dietary equivalent of politically incorrect.

Most of my favorite factoids about obesity are historical ones, and they don’t make it into the new, four-part HBO documentary on the subject, The Weight of the Nation. Absent, for instance, is the fact that the very first childhood-obesity clinic in the United States was founded in the late 1930s at Columbia University by a young German physician, Hilde Bruch. As Bruch later told it, her inspiration was simple: she arrived in New York in 1934 and was “startled” by the number of fat kids she saw—“really fat ones, not only in clinics, but on the streets and subways,...

THE first time I questioned the conventional wisdom on the nature of a healthy diet, I was in my salad days, almost 40 years ago, and the subject was salt. Researchers were claiming that salt supplementation was unnecessary after strenuous exercise, and this advice was being passed on by health reporters. When I spent the better part of a year researching the state of the salt science back in 1998 — already a quarter century into the eat-less-salt recommendations — journal editors and public health administrators were still remarkably candid in their assessment of how flimsy the evidence was implicating...

Ten years ago, science writer Gary Taubes exercised an hour a day. He avoided fat in his diet, never even using milk in his oatmeal. But he kept gaining weight. As an experiment, the self-described carnivore tried the high-protein, low-carbohydrate Atkins diet - eating bacon and eggs for breakfast, pepperoni with melted mozzarella for lunch, and a steak for dinner - and lost 20 pounds in six weeks. Since then, Taubes, an award-winning journalist and best-selling author, has stuck with the diet and spent countless hours collecting evidence to prove that it's not how much we eat but what we...
