You cannot make fat-shrinking body wraps, for the simple reason that such wraps cannot shrink fat. They can reduce the circumference your waist, but that is the result of losing water weight and not fat. The best way to lose body fat is to exercise regularly and eat a healthy diet.
An Old, Unworkable Concept in a New Package
Body wraps that claim to reduce body fat and cellulite -- which is just another form of body fat -- are just a contemporary version of the old rubber belts that promised its wearers that they would lose fat by wearing them. Science has proven that neither the belts nor the wraps work as advertised. They do not shrink fat cells or burn body fat; the only way you can lose fat is through diet and exercise.
