I went from being very obese to losing a little over 50kg and now my body fat percentage is about 13%, but I still have a lot of side fat. To some extent, when I take off my panties, my side belly just looks like it's sticking out a little, but when I put on panties or pants, the side fat is still there. It folds upward as it is lifted, and when I asked about it elsewhere, they said it could be because there is fat on the flanks, but it could also be because the skin on the flanks is saggy. So, by the way, is there a surgery to lift the flank fat? Is it very expensive?
