Your brother would like to lose 20 pounds. He is debating between a new low-carbohydrate diet or a more established low-fat diet. What advice would you give him?

What will be an ideal response?


For the most part, weight loss is similar for people following either a low-carbohydrate diet or a low-fat diet. This is an important point. Weight losses reflect restricted kcalories—not the proportion of energy nutrients in the diet. Any diet can produce weight loss, at least temporarily, if energy intake is restricted. And most weight-loss diets also restrict added sugars.
