Liposuction plus / minus a tummy tuck

Without seeing a picture of you I can't say for sure but at the very least you should explore having liposuction done. This is very effective in the flanks and generally the skin out there is thick and elastic and shrinks quite well. As far as the front of your abdomen goes, it depends on whether you have extra skin or not. If you do, you might need a tummy tuck to get the flattest tightest abdomen possible for your body. If the skin is not in excess and is of good elasticity, you might get by with just liposuction.
