Though body contouring and weight loss both reduce your total body fat, they work in very different ways. Weight loss and weight gain is a process of your existing fat cells shrinking or growing. When losing weight, generally the fat cells throughout your body shrink.
With body contouring, the fat cells are directly removed from a specific area of the body. It has been designed especially for people who are a healthy weight or mildly overweight and want to surgically resolve one or two stubborn fatty areas.
As such, body contouring does not generate the same holistic results as weight loss brought on through diet and exercise.
