Many people think that when you’re fasting, you’re starving. But, you ARE actually eating. I’m going to explain more about why this is in this podcast. 

When you’re fasting, your cells are eating their own fat. They’re not being fed from your diet, but they’re being fed from your storage.

The only time fasting is starving is if you go too long and you've used up all of your fat. If you have no more fat, at that point, the body will start using up its muscles. But that will take a very long time.

Fat gives us glycerol and fatty acids, which turn into ketones. About 60% of the fuel your body uses while fasting is fatty acids. As far as the brain is concerned, two-thirds of the fuel can be ketones, and one-third will be glucose. 

The body does need a small amount of glucose. However, there is something in the body called gluconeogenesis, where the body can make glucose. 

Where does the body get glucose from?

 • Glycerol - 20g of glucose per day

 • Ketones - 10g of glucose per day

 • Recycled lactate - 40g of glucose per day

 • Organs - 80g of glucose per day

 • Alanine - 15g of glucose per day

Our bodies are very well designed for fasting and intermittent fasting. There are a ton of fasting benefits, and the body does will on this. But, the body does not do well on frequent meals and snacks.
