[Picture] Stomach fat making me look pregnant

BTW... I'm not pregnant and have never been pregnant. Idk what is going on. It seems to be in just the one area. It didn't used to be so big. Has anyone else had this problem. What did you do? Please help. I'm starting to work out again and i eat only fish and chicken. Also I only drink one cup of coffee in the morning and drink water for the rest of the day. I'm not a health nut but I'm fairly healthy. Should I be concerned? I can't really lose weight either. No matter how much o restrict or try to eat healthy. My doc doesn't believe me though.
