fat people with belly button

losing belly fat quick.?

ok, I’m 15, 5′ 9″, 145 lbs. many people say I’m skinny, but that is just my appearance with a shirt. See I used to be pretty chubby and I just ate less and dropped the pop. but now, I have my flab on my stomach that I hoped would flatten when I grew, but sadly, no. and I have a hangover on my waistline. and around my belly button and below my small man-boobs, I have these places that are red, almost like wrinkles. Is this abs developing? and how can I get rid of the belly flab, or at least the hangover thing? thanks.
sorry about the length and I don’t want to lose weight, just my stomach

i dont care about weight and you could ask better shorter questions
