Where Did All My Fat Go???

Wednesday, September 26, 2018


I’ve lost 90 pounds and started to wonder where did all that fat go...how did it really leave my body?


I’m also amazed at the miracle of how the body maintains a symmetrical shape and not an “out of proportion or lopsided body” with one side bigger or smaller than the other as the pounds come off and the fat disappears.


When you lose weight and ask “Where does the fat go?” It turns out, most of it is exhaled and breathed out as carbon dioxide and goes into thin air. This surprised me because I thought it was excreted primarily in urine and sweat.

Here’s a more technical answer of the process:

The body stores the excess protein or carbs in a person's diet in form of fat, specifically, as triglyceride molecules, which consist of just three kinds of atoms: carbon, hydrogen and oxygen. For people to lose weight, their triglycerides must break up into building blocks, which happens in a process known as oxidation.

When a triglyceride is oxidized (or "burned up"), the process consumes many molecules of oxygen while producing carbon dioxide (CO2) and water (H2O) as waste products. So, for example, to burn 22 lbs. of fat, a person needs to inhale 64 lbs. of oxygen. And the chemical process of burning that fat will produce 62 lbs. of carbon dioxide and 24 lbs. of water, the researchers calculated.

The researchers showed that during weight loss, 84 percent of the fat that is lost turns into carbon dioxide and leaves the body through the lungs, whereas the remaining 16 percent becomes water, according to the study published today (Dec. 16) in a special Christmas issue of the medical journal BMJ.


These results show that the lungs are the primary excretory organ for weight loss. The water formed may be excreted in the urine, feces, sweat, breath, tears or other bodily fluids, and is readily replenished," the researchers said.
