To the Editor In a Viewpoint,1 Dr Guth said that the challenge of weight loss is to “convince patients to consume fewer calories” and benchmarked weight loss success against the 3500 kcal per pound rule. This view suggests that small decreases in diet calories will progressively result in substantial weight losses. However, the real relationship between diet calories and weight loss is more complicated.
