Hey, I'm trying to figure out a diet for my brother. He's 16, 170 pounds, 5'8", and although I am not trying to sound insulting, he is a pretty big fat guy. He works out and does Tae Kwon Do with me, so making sure he maintains muscle mass or if possible increase mass is a bit of a priority, but at the moment, getting him to shed some fat is far more important. I recommended he try eating similarly to me though I realized that he is a bigger person and therefore even if he is trying to lose fat has to consume more calories, so I'm not quite sure where to begin. Any advice would be greatly appreciated. Thanks.
