Yes it is possible. Undergoing liposuction is equal to a diet. When you make a diet and lowers certain amount of weight, you must be careful not to regain that weight through a balanced diet, exercises, etc. With liposuction is the same. The results can be the best, however, if you do not take care, you will gain weight and get fat. The advantage of liposuction is that if that weight gain is not exaggerated, when you return to lose those extra kilos, will again have the same shape it had when it was operated.
