Effect of Dietary Protein Content on Weight Gainr Energy Expenditure, and Body Composition During Overeating.

The article evaluates the effects of the overconsumption of low, normal and high protein diets on weight gain, energy expenditure, and body composition. The result of the randomized controlled trial of male and female volunteers revealed similar levels of body fat increase in all the three protein diet groups that represented 50 percent to more than 90 percent of the excess stored calories. Observation showed no changes to the resting energy expenditure, total energy expenditure, and body protein in the low protein diet group. Volunteers in the normal and high protein diets exhibited an increase in resting energy expenditure, body protein or storage of lean body mass, but not body fat storage.
