It’s the Calories, not the Protein

Weight-stable patients living in an inpatient clinic for 10-12 weeks who overate by 954 kcal per day on low-protein diets, gained less weight than those who ate the same amount on normal- or high-protein diets. But they all gained a similar amount of fat. The protein level of the diet did not affect the amount of fat each patient stored.

PositiveTip: Avoid eating excess calories: they will increase the fat you store no matter how much protein you eat.
