Intermittent Fasting

Intermittent fasting restricts the window during which food is consumed. The 16:8 protocol is the most popular. During fasting, insulin drops and the body shifts to burning stored fat. After 12-16 hours, autophagy is upregulated — the cellular cleaning process linked to cancer prevention and longevity.
