The total number of fat cells in your body is constant once you reach adulthood. These cells will get bigger or smaller as you gain or lose weight, but the number of cells remains the same. CoolSculpting destroys fat cells in the treated area and they are eliminated for good. So, it actually reduces the total number of fat cells you have in your body, and makes it so your body cannot store as much fat in the treated area as you could have before, leaving that area “sculpted” even if you gain weight in the future.
