Or at least the appearance of stomach fat? It seems when on this protein my stomach was not going down. Last night after a workout with strictly weights, I used no protein and just made a chicken salad, and had my usual scoop of creatine. This morning, my stomach instantly appeared smaller. I usually used Optimum Nutrtion protein after boxing and Jiu Jitsu workouts as well. I wonder if somehow or another my body does not benefit from this protein.
