I'm very fortunate to have been blessed with a flat stomach. Hope it remains that way.
Growing up, my parents made me believe that a flat belly was not a good thing. I would hear comments like "Gade po vant tifi a" "Po vant li kole ak do'l". I was a clueless kid, so I'd eat everything they'd feed me, hoping that my belly would get bigger. Lucky for me, it did not work. Even nowadays, I eat a lot of junk food ,It still doesn't work. You know, some things just aren't meant to be.
Girl, I haven't done it, and I dunno anyone either who had liposuction. Personally, I'm not a big fan of surgery. Why don't you hit the gym? get a personal trainer and see what happens.
From what I heard, it's not worth the risk. They will only get rid of some fat in your belly area, you probably will have more left in every corner of your body that will eventually expand. HIT THE GYM TO BURN FAT INSTEAD!!..Wake up early in the morning to take long ass walks. Mow the lawn

......there are many ways to burn fat..really.
Whatever you decide to do, good luck.
