When someone loses weight, where does the fat actually go? What happens to it?

The fuel that your body runs on is called glucose. You get most of your glucose from carbohydrates. Ideally, you will only take in enough to use. If you take in more carbohydrates than you can break down you will store it as fat. If you begin to use more carbohydrates than you need to fuel your body, you have alternate pathways to break down fat which can be converted into glucose. So the fat is converted back into carbohydrate and used as fuel for your body.

Van Hoeck

Fat is the means through which your body stores energy in the form of large complex molecules. When you lose weight your body tapes into its energy stores (fat) and breaks down these molecules through metabolism. These molecules end up in all sorts of places, sometimes as amino acids, sometimes as other proteins, but most of the time they are broken apart and filtered through your metabolic process to produce energy.

Saundra Sample

In the body, fat is combined with oxygen to make carbon dioxide and water. Both of these products are excreted, mostly in the breath.
