But when you gain the weight back, the fat cells still remain in the typical male fat store areas (mainly the belly), so when you gain the weight back, the fat will still go to the same places it used to before you started HRT, and maybe a little will gradually start going to female fat store ares like hips and butt (it takes several years). And if you try to gain a lot of extra weight hoping for bigger hips and butt, you will probably just get a bigger belly. So, liposuction is really the only way to remove the old fat cells, however, if you gain a lot of weight after liposuction, then even though those fat cells were removed, they will increase in size. So, the best thing to do is eat well, and make sure you are getting enough protein (the building blocks of life; and everything in your body depends on it from good skin, good muscle tone, beautiful hair and nails, everything) and good fat (the right kind of fat will create high density lipids that protect your heart, and bad saturated fat will create low density lipids that block your arteries and cause cardiovascular disease). And stay at a Healthy weight and BMI; and exercise.
