Increasing protein intake from 15 percent to 30 percent caused patients to lose an average of 10.8 pounds in three months, including a loss of 8.1 pounds of body fat according to a recent study. Subjects
Subjects : 19 people, 30% protein for three months
The study involved 19 people who were fed a diet of 15 percent protein, 35 percent fat and 50 percent carbohydrates for two weeks to maintain their weight, then they were switched to a diet of 30 percent protein, 20 percent fat and 50 percent carbohydrates for three months.
No calorie restrictions
There were no calorie restrictions.
Increased protein, no decrease in carbs
Weight loss due to increased protein and decreased fat, no change in carbohydrate
“We found that an increase in dietary protein content comparable with that observed in popular low-carbohydrate diets, but no reduction in dietary carbohydrate content, resulted in rapid losses of weight and body fat,” the authors noted.
“It is likely that a reduction in dietary fat by 15% of total energy contributed to weight loss in the present study,” the authors also stated.
