I believe they usually write this becuase they expect you to be working out and building muscle which as we all know muscle ways more than fat(atleast i hope we do)and i am taking this along with protein packets and have went from 135 to 165 but the thing is i am not gaining fat just muscle and my fat is slowly going away and i do mean slowly but it is still going away and that is the important thing.You just have to train hard.
