Weight gain after Zeltiq


Your question is a common one--where will the fat go? Unfortunately there is no one answer to this question.  After doing Zeltiq, whether it be once or multiple times, some fat cells will undoubtedly remain in a given area.  If a patient gains weight following a procedure like Zeltiq or Liposuction it can certainly still "show up" in the area  that was treated or perhaps it may collect more easily in another area or may be more evenly distributed to all of the fat cells....hard to say.  Though our bodies are similar, they are not all the same. One can never be sure where the Christmas cookies will land. Hopefully after spending your money on having Zeltiq done and achieving the results you want you'll be motivated to stay at that particular weight and shape and not sabotage your new may be easier to be conscientious and not gain the weight, regardless of placement, than to have to struggle and diet to get rid of it again.

Good luck~

Weight gain after Zeltiq CoolSculpting

Similar to liposuction, there will be less fat cells after zeltiq than before and if weight is gained, it will go less on the areas treated than the non treated areas of the body. The residual cell in the CoolSculpting area can gain more fat if you overeat.

Weight gain after Zeltiq Coolsculpting

The beauty of the Zeltq procedure is that the destroyed fat cells are permanently lost.  If you maintained the same weight and eating habits, you definitely will not regain the lost fat layer.  If you gained a significant amount of weight after Zeltiq, your remaining fat cells could enlarge and you may notice some increase in the fat layer, but you would tend to build the fat layer in other untreated areas first, and the area treated with Zeltiq would stay relatively slimmer.  Those treated areas never return to baseline.  So for most purposes, the results of Coolsculpting can be considered permanent.  Minimal holiday weight gain would not cause any noticeable changes in the treated area.

Weight gain after CoolSculpting, but maintaining less fat in treated area.

Because with CoolSculpting by Zeltiq there is permanent damage to fat cells with permanent removal of fat, in the event of future weight gain, there should be far less fat redepositing in the areas treated with Zeltiq, as compared to other areas.

Weight gain after Coolsculpting

The theory is that after Coolsculpting fat cells die and are removed through natural metabolic processes. Thus, those cells, in theory , are gone forever. Coolsculpting has not been around long enough to validate but this has held true so far in the last five years of Coolsculpting's existence. If you were to gain weight after the procedure, then theoretically that fat distribution would be preferentially in areas that were untreated though treated areas sill have significant numbers of fat cells remaining and those would be affected as well.

What happens if you gain weight after Zetliq CoolSculpting?

This is an excellent question.  The number of fat cells we have are stable once we reach our adult years.  What happens when you gain weight is that your existing fat cells get larger rather than getting an increase in  number of fat cells.  With Zeltiq CoolSculpting, fat in the treated are will crystallize resulting in damage to the fat cells.  These damaged fat cells are then removed through a natural biologic process called apoptosis.  Apoptosis is the body's way of removing damaged or senescent (old) cells.  Once these fat cells are removed they should not return.  If one were to put on weight after CoolSculpitng your remaining fat cells in the treated area can get larger but being that you have removed a portion of them the current thinking is that you would gain preferentially in  other areas of the body.

Weight gain after zeltiq

The most interesting part of the Coolsculpting treatment is that once the treated fat cells have been removed they will not come back. You have a fixed number of fat cells in your body by the time you reach late adolescence. By physically destroying those fat cells they can not regenerate. You certainly can gain weight, but it is usually proportional and you should still be able to see the area that was treated. In some of the photos the company has they show one of their sales reps who had one side treated and not the other. He subsequently gained 20 pounds and you are still able to see exactly where his treatment was.

Weight gain after Coolsculpting

Thank for your question.  You will find that the area that is treated always remains smaller than what it would have been should not had Coolsculpting.  The procedure permanently kills off fat cells.  That means your remaining cells can expand with weight gain, but you have fewer cells in that region that can expand.

Will fat cells return with weight gain?

The Coolsculpting procedure literally kills the fat cells in the treated area, if weight is gained following the procedure, some of the fat could come back, but typically it would return to a different area of the body. 

Contour improvement after Coolsculpting is permanent

The contour improvement you gain from Coolsculpting is permanent and is irregardless of whether you gain weight. That being said, the 20-25% reduction you will experience from Coolsculpting means that there are still 75-80% of fat cells remaining. Therefore, the remaining cells can still get larger but the treated area will always look better for having done Coolsculpting. Fat goes to where there are fat cells. Any weight you gain will be redistributed to all your fat cells, and just less will go to the area that you treated with Coolsculpting than it previously would have.
