Other than the obvious which u do not want to hear, u go to another doctor. And if that doctor wo not do it, u go to another one. Do not go to a quack, though! Make sure that any doctor u go to is respected & licensed & has no complaints against him/her.
A doctor may be willing to help u develop a plan to balance ur body so that u can lose the weight necessary to make liposuction worthwhile. A tummy tuck may be something they r willing to do, or if u only have a little fat on ur thighs & carry the rest in ur belly, they may be willing to lipo ur thighs or hips, or whatever.
Good luck, I wish I had the money to pursue a solution like that. Alas, I am forced to just exercise & save my pennies in the hopes of someday getting a body lift when I finally lose the weight & end up with gross saggy skin!
