In Good Calories, Bad Calories, Taubes tries to bury the idea that a low-fat diet promotes weight loss and better health. Obesity is caused, he argues, not by the quantity of calories you eat but by the quality. Carbohydrates, particularly refined ones like white bread and pasta, raise insulin levels, promoting the storage of fat.
Taubes is a relentless researcher, shining a light on flaws in the scientific literature. For example, he charges that when scientists figured out how to measure cholesterol in the blood, they became “fixated on the accumulation of cholesterol in the arteries as the cause of heart disease, despite considerable evidence to the contrary.”
