Which of the following 3200-calorie diets is the least fattening
high fat diet
high carbohydrate diet
low carbohydrate diet
all of these choice are equally "fattening"
high protein diet

I think the correct answer from the choices listed above is the last option. It is the high protein diet would be the 3200-calorie diets that is the least fattening. A 3,200 calorie per day diet plan is ideal for athletes who need the additional calories to help compensate for the calories burned during training and competition.
