Will cool sculpting get rid of 20 lbs of stomach fat?

CoolSculpting is a treatment for subcutaneous fat.  This treatment is not a weight loss option.  It used to target small stubborn fat pockets.  The treatment kills fat cells and they are excreted by the body.  You do not lose weight with this procedure.  This procedure is used to sculpt areas of stubborn fat.  A weight loss plan may be best for you and then you could see if CoolSculpting may be an option for you after weight loss.

CoolSculpting is not a treatment for weight loss. It is most effective in removing stubborn pockets of fat that are resistant to exercise, usually small pockets of fat around the abdomen or things such as love handles. CoolSculpting is most effective if you are already at your goal weight and are looking to add contour to your shape. CoolSculpting does not offer the kinds of dramatic results you might see following liposuction or a tummy tuck. If you have tried diet and exercise and you still find that you are having trouble losing weight you should book an in person complimentary consultation with a board certified plastic surgeon in order to assess whether there is a procedure that meets your goals and needs.

no cosmetic surgery except for Lap band or any GI surgery are for weight loss. they are all for small problem areas and contouring.
If you have small problem areas you can use non invasive methods like coolsculpting with vanquish or TrusculptID to get small areas of fat reduced.  Skin also tightens if you combine this with exilis ultra, venus legacy, Inmode Forma/Contoura radiofrequency treatments.  You boost the results from coolsculpting if you add in Kybella injections to melt fat as well.  We also combine coolsculpting with shock therapy like Z wave, EVIVE, and cellutone to get even faster results, more improvement, and less risk of combinations like nodules, swelling, neuropathy or paradoxical hyperplasia.  Best, Dr. Emer.
