Саммари «Good Calories, Bad Calories»

In Good Calories, Bad Calories, science journalist Gary Taubes argues that the conventional wisdom linking dietary fat, cholesterol, and excess calories to obesity and heart disease rests on weak or misread evidence. The book, published in 2007 and also titled The Diet Delusion in some markets, is structured in three parts: "The Fat-Cholesterol Hypothesis," "The Carbohydrate Hypothesis," and "Obesity and the Regulation of Body Weight." Taubes traces the history of nutrition science from nineteenth-century calorie counting through Ancel Keys's Seven Countries Study and the 1977 McGovern Committee hearings that cemented low-fat advice in U.S. dietary guidelines. His central framework is the carbohydrate hypothesis: that refined carbohydrates and sugars drive insulin secretion, which promotes fat storage and hunger, making obesity a hormonal disorder rather than a simple energy-balance problem. He draws on researchers including John Yudkin, Peter Cleave, and Alfred Pennington, and revisits experiments such as the Vermont Prison Overweight Study and the Framingham Heart Study's ambiguous findings on cholesterol. Taubes also examines populations like the Inuit and the Pima, contrasting their traditional diets with post-industrial eating patterns. The book does not prescribe a meal plan; it is a historical and investigative work. Taubes concludes that the evidence for restricting fat is insufficient and that carbohydrate restriction deserves serious reexamination. The work became influential in low-carbohydrate and keto communities, though it has drawn criticism from mainstream nutrition researchers who dispute its selective use of evidence.
