Fat cells cannot multiply in adulthood. This means that liposuctioned fat cells are not replaced by the body. If the body absorbs more energy than it uses, the energy is stored in the body’s fat cells. As a result, the fat cells become larger. The ability of fat cells to store energy is not affected by liposuction. Liposuction therefore cannot prevent the body circumference from increasing with weight gain. However, the increase in circumference will be less in the suctioned regions than in other parts of the body.
