STOP Eating for 3 Days?! (72 Hours)

DR. ERIC BERG
About this episode

What happens to your body during a 3-day fast? In this video, we’ll cover the fasting health benefits of both intermittent fasting and extended fasting for 72 hours or longer. I’ll also share some expert fasting tips for even more fasting benefits.

Did you know that insulin resistance is behind most chronic diseases, including many types of cancer? Frequent eating leads to insulin resistance, which blocks cells from getting fuel. Diets involving 5 to 6 small meals daily destroy the metabolism the most!


An intermittent fasting plan involving 18 hours of fasting with a 6-hour eating window can provide tremendous health benefits, such as weight loss in the midsection, improved mood, and decreased inflammation.


A 24 to 48-hour fast can significantly magnify the benefits of fasting. Extended fasting enables you to deplete the stored glycogen in your liver. You may also notice significant initial water weight loss.


During a 1 to 2-day fast, most of your fuel will come from ketones. Your microbes will thrive, and growth hormone will increase, boosting muscle growth and burning fat.Ketones will feed the neurons in the brain, so you may notice improved cognitive function.Extended fasting allows you to get into a state of autophagy, where your body removes damaged cells and proteins and creates new ones. Autophagy also allows you to build new brain cells.


A 3-day fast can produce even more benefits! Extended fasting for 72 hours can clean up intracellular pathogens, including Epstein-Barr and herpes viruses.


A 3-day fast can stimulate your immune system, protecting you against cancer and autoimmune diseases. You can achieve results similar to stem cell therapy for free!


If you’re unsure of how to fast and want to make the process as comfortable and beneficial as possible, try these fasting tips for the most fasting benefits:

•Coffee and tea are okay during a water fast

•Make sure you have enough sea salt

•Consume electrolytes like potassium and magnesium


Refeeding can have a negative impact after a 3-day fast. It’s best to rebuild your caloric intake slowly. Bone broth is a great option to break your fast.
