Liposuction surgery is virtually non-rebounding. The number of fat cells in the human body is relatively fixed after adulthood. Liposuction surgery removes some of the fat cells, so that the overall number of fat cells is significantly lower than before surgery. Although individual fat cells may increase in size to varying degrees, after the absolute reduction in number, the total fat cell volume generally cannot increase to the sum of the pre-operative volume, and based on the number perspective, liposuction surgery is not rebounding. The main reason for obesity is that the consumption of fat is too little, such as lack of exercise and overeating, which will make the body store a large amount of energy that cannot be metabolized in the adipose tissue, and the final result is that the volume of fat cells becomes larger, which is reflected in the macroscopic view that people become fat. If after liposuction, the patient continues to eat according to the previous diet without control, the body will store the excess energy in the remaining fat cells, and then increase the volume of fat cells, resulting in the so-called rebound, causing a recurrence of obesity, but the degree of obesity will be reduced. Therefore, the life and eating habits after liposuction must be strictly controlled in order to maintain a beautiful body for a long time. Liposuction is not weight loss, but only the removal of local fat, which has very little effect on the fat of the whole body. Therefore, it is recommended that beauty lovers lose weight through exercise and dieting methods, and its effect will be more obvious.
