Fat is not heavy compared to its volume. A single pound of fat is the size of a pound of butter. When you think about reducing fat from a localized area, a small weight change makes a big difference. When you look at before and after photos of CoolSculpting results, the best examples will be those that show little or no weight-change. If the weight has not changed the fat-loss is clearly a result of the treatment, not weight-loss results from diet or exercise.
