I've stopped drinking diet drinks. Like pepsi or 7-up, stuff like that. I don't drink them anymore, I might eat some snacks but rarely, I imagine I have to cut them too? I'm 17 and wait about 145 pounds, I'm not fat but I want to get into great shape and have nice abs. So, what should I eat? A lot of proteins I know about that but what exactly? Steaks? Eggs? And what shouldn't I eat? And what can I eat ''occasionally''?
