Liposuction while 100 pounds overweight

This is not a discussion for calories in vs calories out or liposuction to get rid of all 100 lb.

Suppose a woman is looking to lose about 100 pounds and is dieting and exercising. I picked that number as many plastic surgeons won’t do lipo when that much overweight* but at that weight lipo should have some impact. But suppose a woman wants some lipo to complement her weight loss meaning to add some contour to her arms, legs and butt to complement her dieting and exercise plan as she is going through this process. Add to this the metabolic impact of removing a significant fraction of fat as she is on her diet/exercise program and for good measure add on a tummy tuck to fix all of the physical damages a few pregnancy has wrought on her abdomen.

How much fat could reasonably be removed? What will happen as she continues to lose weight? Will her dieting be more effective physically due to less fat? What would happen to the contouring as she continued to lose weight? Are there any medical concerns that she should be aware of beyond those general to lipo?

I’ve also seen reference to the so-called mommy makeover where a tummy tuck is combined with breast augmentation but every now and then it is a breast lift where fat from the lipo is used to sculpt the breast with minimal cutting. Is that really a thing? Can fat lift a breast like that or does it just fill it out?

*If this is wrong please correct me

It is a subject of some controversy and little data.

The concern is first that a higher ratio of visceral to subcutaneous adipose tissue (VAT/SAT) is an independent risk factor for adverse outcomes. It is possible that altering that proportion upward by surgical removal of SAT may have adverse metabolic impacts.

Another concern, as mentioned in the linked abstract, is that there might even be “compensatory growth of adipose tissue in response to lipectomy” (possibly specifically more higher risk VAT). This effect of liposuction might make it harder for diet and exercise to result in more fat loss and thereby blunt the positive health impacts of diet and exercise.

But it is a lot of “mights” with very sparse data and the little there is apparently does not support the case for great concern, in particular in the context of an ongoing serious nutrition and exercise plan (as is your hypothetical).

So as a GQ - the answer is currently unknown.
