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.

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!

Dead fat cells are processed by your liver

Coolsculpting causes a natural process causes apoptosis, or "programmed cell death," of the treated fat cells. Once dead, they are cleaned out of the fat layer by your body's immune cells, and are then metabolized by the liver and excreted from the body.

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.

Where the fat goes after CoolSculpting

You shouldn't expect to loose weight but you can expect to loose inches. Freezing fat cells creates cell death and then the body is able to naturally get rid of the fat cells though all the normal way that your body gets rid of cells, all the time.

Coolscupting Treatment

The treated fat cells are crystallized (frozen), then die. Over time, your body naturally processes the fat and eliminates these dead cells. The CoolSculpting fat freezing procedure is FDA-cleared and safe to use in the neck area.

Fat Leaves Through Kidneys

This is quite a common question, and a good one. CoolSculpting causes the breakdown of fat cells in a natural process called apoptosis. At this point, the body's waste system takes over, filtering the fat cells out through the kidneys so that they leave the body along with the urine. You are right in that CoolSculpting does not produce a significant weight loss. Although you will shed unwanted fat cells and can reshape and tone areas of the body, you won't likely see a significant change on the scale.

"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.
