Abdominal lipo- Putting on weight before procedure?

There is no benefit to gaining weight before liposuction. If anything, you will make it more likely that skin will not retract and that the end results will not be as good. Liposuction results are best when it is used to treat small trouble areas that still persist after patients have done all they can to get in the best shape possible. Gaining weight would be counterproductive. 

Generally speaking, the ideal patient for liposuction surgery is one who has achieved a long-term stable weight, is medically (psychologically and psychosocially) stable and presents with diet and exercise resistant adipose tissue of  specific areas, with good quality overlying skin elasticity. When the time is right, seek consultation with well experienced board-certified plastic surgeons who can provide you with good, specific, and ethical advice. Best wishes. 

This all comes down to precision of surgery.  I think you should be at your lowest weight, but it is easier to liposuction if you have more fat.Liposuction results are highly surgeon dependent. Find a board certified plastic
surgeon who performs hundreds of liposuction and liposuction revision
procedures each year. Then look at the plastic surgeon's website before
and after photo galleries to get a sense of who can deliver the
results. Kenneth Hughes, MD Los Angeles, CA
