Husband likes pre-pregnancy body!!

Is mommy makeover a weight loss procedure? My husband is compelling me to undergo mommy makeover surgery from a clinic in Barrie ( http://www.lakeviewsurgery.com/cosmetic-surgical-procedures/mommy-makeover/ ).
He says it is better to reverse the unwanted changes in my body like sagging breasts, loose skin, and stretch marks that have appeared after childbearing. I have tried dieting and exercise to improve this but was not successful. He said that he likes my pre-pregnancy body. So I'm thinking to give it a shot. It's the first time he is asking me to do something.
While researching online, I saw that it is better to diet and exercise before considering mommy makeover procedure as it helps in fast recovery. It is also mentioned that the complications will be lower for those who have a healthy lifestyle. So how long should I wait to have a mommy makeover? I don't want to take any sorts of risks. I'm currently 210 lbs. How much weight should I reduce before considering this procedure? I would like to have a smoother and shorter recovery period. Any suggestions are highly appreciated. Thanks!!
