Whether you try intermittent fasting, 24-hour fasts, or prolonged fasts, the science is overwhelmingly in favor of most fasting practices.

 
Research indicates that fasting improves

• arterial health
• cognitive health
• digestive health
• longevity
• DNA
• body composition
• sleep quality and duration
• and numerous other aspects of health.

Many of the benefits of fasting come from the cellular clean-up process known as autophagy. Science shows that this process reduces inflammation, increases immunity, and is even important for fighting cancer.
