Description
When you don’t eat for a while, several things happen in your body
For example, your body changes hormone levels to make stored body fat more accessible and initiates important cellular repair processes.
Here are some of the changes that occur in your body during fasting:
- Insulin levels. Blood levels of insulin drop significantly, which facilitates fat burning.
- Human growth hormone (HGH) levels. The blood levels of human growth hormone (HGH) may increase dramatically. Higher levels of this hormone facilitate fat burning and muscle gain, and have numerous other benefits.
- Cellular repair. The body induces important cellular repair processes, such as removing waste material from cells.
- Gene expression. There are beneficial changes in several genes and molecules related to longevity and protection against disease).
Many of the benefits of intermittent fasting are related to these changes in hormones, the function of cells, and gene expression. When you fast, insulin levels drop and human growth hormone (HGH) increases. Your cells also initiate important cellular repair processes and change which genes they express.
