so I am in college, and I am 20, male, usually i can eat whatever seems good and not see a change on my stomach...But lately I packed on a whooping 5 pounds...last quarter I ate usually really late and didnt exercise much...but now im gaining waist fat...I am actually eating less right now cause I hate cooking, and no longer live in dorms close to cafeteria....so why am I gaining weight? I dont even eat breakfast sometimes and sometimes i starve until I cook something later....shouldn't I be losing weight??? what the heck? I am actually eating less meat, more veggies...

is my body metabolism going down at age 20?
I also get a lot more acne problems than I did just one year ago?


This can't be a late puberty issue right? I am twenty for crying out loud, but my body seems to be getting all f'ed up now.
