Do mommy makeover candidates need to be a certain weight?

Let’s say I wanted to get a mommy makeover. Would it be beneficial for me to lose weight prior to surgery, or does it not really matter? Is there an ideal weight or BMI that I should be aiming for? I am 5’ 6” and currently weight 171 lbs, but would like to eventually lose 20 lbs.
