Is CoolSculpting able to be done if you are 100 lbs over weight?

CoolSculpting is a very effective procedure for treating small pockets of fat. It is not, however, a weight loss procedure, and is generally not used to address larger amounts of fat accumulation. Further, CoolSculpting is not recommended for people who have a BMI greater than 40. Therefore, the best candidates for CoolSculpting are those who have maintained a healthy, steady weight for several months but have a few small problem spots they'd like treated without surgery.
 

CoolSculpting is not a weight-loss technique and wouldn’t have any real benefits for you if you are 100 pounds overweight. CoolSculpting is highly effective at eliminating small pockets of fat that don’t respond to diet and exercise. But the only thing that will remove a significant amount of fat is a healthy weight-loss program that emphasizes nutrient-rich foods and varied exercise. Once you lose most of the excess weight and are ready for CoolSculpting, be sure to consult a board-certified dermatologist who has been certified by Zeltiq as an expert. 

Thank you for your question. Coolsculpting is designed to target relatively small discrete areas of fat that a patient is having difficulty to lose. It unfortunately is not a treatment for weight loss. Therefore, it is not recommended for patients that have a significant amount of excess weight.
