Girls who love beauty are eager to have a devilish figure, but after experiencing the torment of dieting and the exhaustion of exercise, many girls find that the body “fat” is not reduced but more, why is this? The essence of obesity is the increase or relative increase of adipose tissue, fat increase is mainly due to excessive calorie intake and reduced calorie consumption. Adipose tissue increase or relative increase is mainly reflected in the number of fat cells and the size of the volume of the change. Before puberty, obesity is mainly due to the increase in the number of adipocytes, after puberty, the number of adipocytes maintains a dynamic balance, and at this time, obesity is mainly due to the increase in the volume of adipocytes. Subcutaneous fat is divided into superficial adipose tissue and deep adipose tissue. Superficial adipose tissue is metabolic fat, which is characterized by easy synthesis and storage, and easy decomposition. Deep adipose tissue is resting fat, which is characterized by low metabolism, easy synthesis but not easy decomposition. Reducing caloric intake (e.g. dieting) and increasing caloric release (e.g. exercise) mainly affect superficial adipose tissue, but have little effect on deep adipose tissue. Superficial adipose tissue is widely distributed in all parts of the body, and deep adipose tissue is distributed in certain specific areas, such as the lower abdomen, waist, buttocks, and the inner side of the upper 1/3 of the thighs. Obese people have more fat mainly in the deep layer of adipose tissue. When obese, the deep layer of fat thickening is obvious than the superficial layer of fat, and the deep layer thickening can be 8-10 times larger than normal, while the superficial layer of fat thickening is only 2 times normal. Diet, exercise and many other weight loss methods can only reduce the volume of fat cells (mainly shallow adipose tissue) to achieve the purpose of temporary weight loss. Once you stop dieting or reduce exercise, the deep fat layer increases quickly because the ability of deep adipose tissue to absorb glucose is 2-4 times higher than that of superficial adipose tissue, and the rate of fat synthesis is faster than that of superficial adipose tissue. The old fat is not lost, new fat is added, and the weight increases, even faster than before the weight loss. Weight-loss people have to take weight-loss measures again, and the cycle repeats itself, forming a vicious circle. This is like the water in the pool, the original water did not drain out, the new water flowed in, the pool of water stored more and more. This is the reason why the more you lose, the fatter you get. The more you diet and exercise, the fatter you get, so how to lose weight effectively, fat suction (also known as liposuction) can effectively remove deep fat tissue, reduce the number of deep fat cells, to achieve immediate weight loss results. Domestic experts through the clinical observation of tens of thousands of patients found that the probability of obesity rebounding after liposuction is very small, even if the patients who gained weight after surgery due to eating more, the thickness of the fat in the aspirated area is mostly thinner than before surgery.
