Dr. Hyman attributes the rising rate of obesity in America to the fat-free diet craze of the 1990s, pointing out that fat consumption does not have as strong a correlation with weight gain as sugar consumption. A study found that rats became more addicted to artificial sweeteners than to cocaine, in part because the sweetener activated multiple pleasure centers across the brain. Furthermore, he points out that artificial sweeteners are significantly sweeter than real sugar, activating an evolutionary preference for sweetness that can lead to overeating.
Dr. Hyman also refutes the perception that it is possible to exercise away the consequences of a poor diet. While exercise is important for maintaining good health, it is not feasible to burn off the calories from sugary sodas and Gatorade. Rather than substitute sugary drinks with low-calorie or sugar-free options, Dr. Hyman advocates eating and drinking what he labels "real food" to promote health and weight loss.Learn more about Nutrition & Diets
