What happens to new fat accumulated in the body once the old fat cells are frozen or destroyed through CoolSculpting?

Dear Pianostrings:
If you have a treatment that eliminates fat cells, those cells will die and not return. When you gain weight, all the fat cells of your body get larger because they need to store more fat, and when you lose weight, they all get smaller. Without any treatment, you have a given number of fat cells at birth, and that number does not change throughout your lifetime (with the exception of someone who is severely obese, in which case the cells can increase in number), but with treatment, the number of cells in the treated area is permanently reduced. Those cells will not be replaced with new cells, and you will reduce the volume of fat in the area you treat. And you will put less fat on in the treated area with weight gain than you would have had you never had the treatment. Relative to the rest of your body, you will always have less fat in the treated area than you did before. 
Now, this is a bit of a simplification, since there are factors that influence the amount of fat that will be stored in the fat cells in different areas of the body. For example, cortisol and insulin allow more fat to be stored in the fat cells around the waistline. But with regard to your question, it is fair to say that fat will not move from one part of your body to another after localized treatment.
This of course assumes that you have a treatment that allows the cells to enter apoptosis and die. There are treatments out there that only injure the cells or empty them of their fat, but when they recover they will take on fat again, and the fat reduction will only be temporary. #CoolSculpting does kill the fat cells, as does #Kybella.All the best,   Dr. Clark

Thanks for your question and sorry that you were not told certain important things after your liposuction procedure.  The fat removed with CoolSculpting will not come back and with proper diet and exercise, can be maintained permanently. If you gain weight, the fat cells that are left behind will grow and affect your overall condition.  So if you are gaining size in the areas that were taken care of, it is because you probably have not kept up with your diet and exercise pattern – which also must be done here.

Coolsculpting spot treats fatty tissue . It will remove 20-25% of the subcutaneous fat for a localized treated area. You stilll have remaining fat cells in that area plus other areas of the body . Consumed food stored as fat  is then deposited  into adipose cells which are distributed throughout the whole body . Because there are less fat cells in the treated area, there will not be as much stored in that site
