10 Frequently Asked Questions About Intermittent Fasting

4. What Fasting Time Is Most Effective?

During sleep, food is digested and the nutrients sent to the necessary systems. Energy is stored up in fat cells in preparation for more food coming in. If food doesn’t come in following sleep, the body uses the energy stored in fat cells. The process escalates during the next four to six hours with the body burning more fat cells for energy.

Depending on your schedule, skipping breakfast continues to burn fat. For example, you might sleep from 11 pm until 9 am. The ten hours of sleep begins the fat burning process, but the next six hours completes it.
