The weight will not change much after liposuction. But it will look much thinner visually.
Many people have this misconception that they can lose a lot of weight after liposuction. In fact, the weight of fat is very light, and the real weight of the human body is muscles and bones. Liposuction will not lose much weight, but it will reduce the volume of local fat. Therefore, liposuction to lose weight is not to make you thinner, but to make your body more symmetrical.
