Do waist shapers force fat to your hip area, are the results permanent? i heard these do more harm than good, just want a professional opinion

Not a good idea: Think of your body like a balloon, like the long ones that people make animals out of. If you squeeze and tighten one section, the stuff (air in a balloon, all sorts of stuff in a human) being squeezed must pop out in a different section of the balloon or the body. Where else would all the stuff go? Abdominal muscles are vital to supporting the back & abdomen. A corset interferes with ab. muscles.
