Having a Coolsculpting procedure doesn't help you loose weight as the result of the procedure so you won't loose the weight right after a coolsculpting procedure but the coolsculpting procedure does help some in weight loss by reducing body fat.
There is a difference in losing fat and loosing weight though but you should lose at least 50% of the fat but you still need to exercise and stay on a strict diet in order to lose the required weight you desire.
