What happens to fat when you lose weight?

Reading Time: < 1 minute

The fundamental principle behind weight loss is simple: Burn more calories than you consume. Restricting calories forces your body to draw on existing fat stores to power your bodily functions, everyday activities, and workouts.

“The excess carbohydrate and protein are converted into triglycerides, which is a fat found usually in the blood, and the triglycerides are made up of carbon, hydrogen and oxygen — like most compounds in our bodies.

These triglycerides are then stored in our fat cells as little drops, and [ihc-hide-content ihc_mb_type=”show” ihc_mb_who=”2,3″ ihc_mb_template=”1″ ]so when you’re trying to lose weight your body is trying to get rid of those.”

So, when we lose weight, where does the fat actually go?

There was a study which came out recently in the British Medical Journal about this. Essentially, the fat you lose is breathed out as carbon dioxide.

Indeed, the researchers found that “the lungs are the primary excretory organ for weight loss”.

As an example, when you’re trying to lose 10 kilos of human fat, this means you’re going to inhale around 29 kilograms of oxygen and then that will produce 28 kilograms of carbon dioxide and 11 kilos of water.

It’s about breaking down those compounds and then they are exhaled. So when you’re breathing out, it’s the carbon dioxide and the moisture on your breath.
