We do not consciously remind ourselves to breathe, nor do we remind our hearts to beat. Body-fat regulation is under automatic control, like breathing. Our bodies possess an intricate system guiding us to eat or not. After only three weeks, Feltham was developing love handles.Ħ. His waist size positively ballooned by 3.6 inches (9.14 centimeters). This time, the weight gain almost exactly mirrors that predicted by the calorie formula-15.6 pounds (7.1 kilograms). The macronutrient breakdown of his new diet was 64 per cent carbs, 22 per cent fat and 14 per cent protein-remarkably similar to the U.S. Instead, for twenty-one days, he ate 5793 calories per day of a standard American diet with lots of highly processed ‘fake’ foods. So, in the next experiment, Feltham abandoned the low-carb, high-fat diet. Perhaps Feltham was simply one of those genetic-lottery people who are able to eat anything and not gain weight. He gained weight, but it was lean mass.Ĥ.

Even more interesting, he dropped more than 1 inch (2.5 centimeters) from his waist measurement.

Actual weight gain, however, was only about 2.8 pounds (1.3 kilograms). Standard calorie calculations predicted a weight gain of about 16 pounds (7.3 kilograms). The macronutrient breakdown of his diet was 10 percent carbohydrate, 53 per cent fat and 37 per cent protein.ģ. Feltham believed, based on clinical experience, that refined carbohydrates, not total calories, caused weight gain. He followed a low-carbohydrate, high-fat diet of natural foods for twenty-one days.Ģ. But the diet he chose was not a random 5794 calories.

In a modern twist to the classic overeating experiments, Feltham decided that he would eat 5794 calories per day and document his weight gain. Not accepting the caloric-reduction theory, he set out to prove it false, following the grand scientific tradition of self-experimentation. health-and-fitness industry for more than a decade.
