Fasting provides numeral health benefits, including weight loss, blood sugar control, and protection against medical conditions like cancer and neurodegenerative disorders.

Despite the recent surge in popularity, fasting is a practice that dates back centuries and plays a central role in many cultures and religions.

How long should you do fasting?

Autophagy fasting is a dietary strategy that involves fasting for a specific period of time to stimulate autophagy. During a fast, once your body has burned through much of its stored carbohydrate energy resulting in low liver glycogen levels, you enter a state of ketosis, where fats are broken down for energy.

How do we fast accordingly?

Studies show that to trigger autophagy, you need to fast for 16-18 hours. However, the timing of your fast is paramount. Autophagy only begins when fasting in alignment with your circadian rhythm–in other words, it must take place overnight.

Why is 16 hours the magic number for fasting?

While both 12-hour and 16-hour fasting can promote fat burning, it's possible that a 16-hour fast may be more effective. This is because the longer fasting period may lead to a greater depletion of glycogen stores, which can trigger higher levels of fat burning.

What happens to body after 16 hours of fasting?

If you don't eat for 10–16 hours, your body will go to its fat stores for energy, and fatty acids called ketones will be released into the bloodstream. This has been shown to protect memory and learning functionality, as well as slow disease processes in the brain.
