Unfortunately, there is no diet or exercise that will get rid of excess skin. The skin has some elasticity and will contract to a certain extent after it has been stretched such as after pregnancy or after weight loss. But after the skin has contracted as much as it can there is no addition exercise or diet that will cause it to contract any further. The only way to get rid of excess skin is to remove it surgically. That is part of what we do when we do tummy tucks, facelifts, thigh and buttock lifts and many of the other procedures we do to trim up people who have loose skin or have undergone large amounts of weight loss.
