Has anyone heard of positive effects from melatonin, high carb diets, and insulin on breast fat transfer surgery?

I heard that taking melatonin for a week before and a week after breast fat transfer will stabilize the cells and increase fat survivability. Is there any research on this? I also heard that eating more carbs to raise insulin levels causes the fat transfer to take better. Is there any science that confirms this? Is there any scientific research that points to or confirms either of these claims, or any other supplement/diet in increasing fat survival rates? Would it hurt to try these anyway?
