What happens in the body during intermittent fasting?

Intermittent fasting starts many processes in the body:

  • After about 8-12 hours of fasting, your body begins to draw energy mainly from your body fat. In addition, your blood sugar level drops and with it the production of insulin.
  • When blood sugar levels are low, the body can burn your body fat much better. Other hormones that are responsible for burning fat also run at full speed during the fasting period.
  • After about 12-16 hours of fasting, autophagy begins. This is a kind of cellular garbage disposal in the body. The body creates new cells and breaks down sick and broken cells. The functionless cells are then converted into energy.
