Please note that liposuction can suck out local fat such as abdomen, buttocks, thighs, upper arms, mandibles and calves. However, it is by no means to suck up all the excess fat at once. Its ultimate goal is to make you look more "bent over backwards", instead of making your weight plummet from 180 kg to 100 kg.
It can permanently remove excessive accumulation of fat cells in some parts of the human body and reproduce the beauty of the human body. But the weight of fat is very light, and the weight of a mass of fat is not even as good as that of a muscle.
