Some people take growth hormone to get injected — it isn’t recommended, but some take it to heal parts of their body.

At about 18 hours of fasting, you’ll begin to develop autophagy. Autophagy is an exciting event that happens with your body. In autophagy, your body also starts to recycle old, damaged proteins and microbes. One type of protein recycled is the advanced glycated end product.

Here’s the thing — when you combine glucose with a protein, it becomes very sticky, so let’s say you’re on a high carbohydrate diet and that sugar combines with your protein, and it starts to glycate, or destroy some of the proteins in your body, and they don’t function as well as they should.
