It’s no secret that whey protein helps increase muscle mass and strength, but a preliminary study presented at the Experimental Biology Conference has just revealed that it also aids in fat loss.

In this six-month study, 90 overweight subjects were divided between three supplement groups: 1) 60 grams of whey protein per day, 2) 60 grams of soy protein per day, or 3) 60 grams of carbohydrates per day. Each group consumed their given supplement in addition to their regular diet and did not follow a prescribed training program. They simple added the supplement on top of their diet and carried on their life as they normally would. The results showed that the group taking the whey protein lost the greatest amount of weight, which was 5 pounds more than those in the carbohydrate group.
