We randomly assigned 811 overweight adults to one of four diets; the targeted percentages of energy derived from
fat,     protein, and carbohydrates in the four diets were
20,        15,     and       65%;
20,        25,     and       55%;
40,        15,     and       45%;
40,        25,     and       35%.

 The diets consisted of similar foods and met guidelines for cardiovascular health.

 Conclusions
Reduced-calorie diets result in clinically meaningful weight loss regardless of which macronutrients they emphasize.
