WHERE DOES FAT GO WHEN YOU LOSE WEIGHT?

Where does fat go when you lose weight?

Of doctors, dietitians, personal trainers surveyed, over 99% of them were wrong including me.

The most common answer was it turns to muscle: wrong.

Ruben Meerman and Andrew Brown, professor and head of biotechnology and biomolecular sciences at UNSW explained that the most common misconception is that fat is converted to energy but this violates the law of conservation of matter.

The mass of an object never changes no matter how the particles rearrange themselves.

Where does all the fat go?

CO2 and H2O.

Fat is converted to carbon dioxide and water.

You exhale the carbon dioxide and water is secreted through perspiration or when you urinate.

10 kg of fat = 8.4 kg through the lungs + 1.6 kg turns into water

Almost everything that you eat comes out through your lungs.
