With Cool Sculpting, if It is Not Weightloss, Where Does the Frozen Fat "Go"?

Does the fat leave your body?

CoolSculpting by Zeltiq is loss of fat not loss of weight

Losing fat does not mean weight loss as fat is much less dense than muscle and you would need to lose a lot of fat to see the reduction of weight on a scale. Meanwhile the 20% reduction of fat volume in one focal bulge can make a difference in shape and how clothing fits.  The body metabolizes the dead fat cells.

How Does Cool Sculpting Work?

Hello,

The cool sculpting (Zeltiq) will freeze the fat cells (cryoplipolysis) without affecting other tissues; the fat in the adipocytes (fat cells) will freeze at a controlled temperature inducing cellular apopotisis (programmed cell death) hence a permanent solution.

As for the fat within the adipocytes, it will get dissolved into the blood stream at a slow rate without inducing a increase of the serum fat levels worth noting.

So the fat will be used up by your body and the adipocytes that were eliminated will never grow back again.

I hope this helps.

Thank you for your inquiry.

CoolSculpting.... will you lose weight?

Coolsculpting kills 20-25% of the fat cells in the area treated.  As these cells die, your body reabsorbs the fatty acids and the cellular debris and you excrete the excess through your intestines.  You will see the area treated shrink over the next 2-3 months as this happens.  You will not feel, or know that anything is happening in any way other than when you look in the mirror over the next several weeks, you will see that you are getting smaller.  Will you lose weight?  ....a very small amount for each treatment area. 

Where does fat go after CoolSculpting?

The fat cells are damaged by the cold temperature during CoolSculpting and are slowly dissolved and broken down in your body by cells called macrophages. The fat cell particles are then cleared from your body through your lymphatic system and goes through the liver where it is processed out of your body as waste.

CoolSculpting Removes Fat

This is an excellent question and one that virtually all of my patients ask at some point. Understanding the difference between fat reduction and losing weight is helpful. When a person loses weight, the fat cells shrink but remain in the body. If you gain weight, those cells enlarge. CoolSculpting permanently eliminates fat cells by cooling them until they crystallize (or freeze) and begin dying. They are then naturally processed and eliminated from the body through its natural metabolic system. They are gone for good. Remaining fat cells in your body can still enlarge, though, so it's important to stick to a healthy lifestyle to maintain your results. I hope that answers your question!

"Frozen" fat cells are metabolized and naturally eliminated

CoolSculpting freezes fat cells through a process called cryolipolisis that only affects the targeted fat cells; it does not damage surrounding tissue. After the fat cells are “frozen,” they are metabolized by the body and naturally eliminated through urine.

Frozen Fat Filtered Away

Great question! Once fat cells are treated by CoolSculpting, they die in a process called apoptosis. This is a controlled form of natural cell death. Over time, the dead fat cells are broken down and automatically metabolized, filtered out of your body through normal processes. The reason we say CoolSculpting is not weight loss is because it's not intended to reduce large volumes of fat. Instead, patients can expect about a 25% reduction of the treated areas. For many people, this is the perfect amount to treat small, stubborn deposits. While you won't notice a significant change on the scale, you will see improved curves and contours.

Where does the fat go after coolsculpting?

The fat cells are irreversibly damaged during the process.  As they die off, the regular mechanisms of clearing cells is taken up by the body.  They are metabolized and eliminated.  This process will proceed, taking the time it needs to get done.  In the meantime, proper diet and exercise will help produce good and lasting results.

Coolsculpting and weight loss

You may lose some weight after Coolsculpting, but for practical purposes, you may not notice it on the scale unless you are doing multiple regions and getting a considerable amount of fat reduction.
Remember, you are only getting ~20-25% reduction in the treated area.  This may equate to fraction of a pound.  Your weight may fluctuate more than this depending on how much water you drink.  Thus it is hard to measure and see the difference on the scale.  That does not mean you won't see the difference when you look in the mirror or try on the same clothes.

Lost fat

Hi there!
The fat is damaged by the controlled cooling of Coolsculpting.  We have janitor cells called macrophages that find the damaged cells and eventually it gets secreted in your urine.  You lose the equivalent of 2 french fries per day so you don't have to worry about increased cholesterol.  It is a wonderful technology... speaking from personal experience!
