Does the body use fat when starving?
Specifically, the body burns fat after first exhausting the contents of the digestive tract along with glycogen reserves stored in liver cells and after significant protein loss. After prolonged periods of starvation, the body uses the proteins within muscle tissue as a fuel source, which results in muscle mass loss.
Where does fat go when you dont eat?
The correct answer is that fat is converted to carbon dioxide and water. You exhale the carbon dioxide and the water mixes into your circulation until it’s lost as urine or sweat. If you lose 10kg of fat, precisely 8.4kg comes out through your lungs and the remaining 1.6kg turns into water.

How long can a fat person survive starvation?
Total starvation is normally fatal in eight to 12 weeks. In less extreme cases, however, where you are still receiving some calories – particularly if these calories include a high proportion of protein – being fat will help you survive much longer, because your body will be able to meet the majority of your calorie requirements from stored fat.
What happens to fat free mass in the body?
