As with all procedures, patients should be examined by ethical and knowledgable providers to determine their candidacy for treatment with CoolSculpting for fat reduction. If someone has a bulge of the rectus (abdominal) muscle from pregnancy or prior obesity, they will not get an iron board six pack from CoolSculpting or liposuction no matter how much fat is removed. some patients need two or three treatments to get a considerable improvement depending on their fat volume pre treatment. Lastly, some patients actually rely on the procedure to lose weight (and it's not designed to be a weight reduction treatment) and they continue to eat too many calories per day and put more fat back in place after the CoolSculpting is done. Exercise should be continued after CoolSculpting and if one hasn't exercised prior to CoolSculpting, they should begin, if physically possible, after healing from the procedure, to maintain a healthy caloric balance, otherwise you will gain weight again, despite having CoolSculpting, if you eat too much for your energy requirements.
CoolSculpting really works well for many patients. In my NYC practice, CoolSculpting is one of the more commonly performed cosmetic dermatologic procedures and has an extremely high patient satisfaction rating.
