There are so many diets out there claiming to be the one that really helps melt the pounds and we’ve tried them all, right? Low-fat vegetarian, low-fat conventional, moderate-fat Mediterranean diet, high-fat no-carb diet, high-fat with carb diet … the list goes on and on. Well, a new study published by the New England Journal of Medicine showed some startling finds. Diet doesn’t really matter after all. Spurred on by several trials that showed conflicting results on which diet led to successful weight loss, the study tracked 811 overweight participants over two years. Each person was put on one of four portion-restricting diets: low carb, high carb, low protein, and high protein. They also were required to exercise for ninety minutes a week while tracking their calories on-line. What did researchers find? Every single participant lost weight—an average of nine pounds and two inches off of their waists.
