In this video, I want to talk to you about how fasting affects your body. I’ve created a lot of videos on intermittent fasting. But in this one, I want to give you an overview of just how powerful it really is.

Brain - Fasting stimulates BDNF (brain-derived neurotrophic factor). This stuff is like Miracle Grow for the brain. BDNF helps repair and regenerate neurons. Fasting also helps with stress resistance, neurogenesis, mitochondrial production, and reducing inflammation.

Liver - Intermittent fasting helps improve your liver by restoring insulin sensitivity. Fasting also helps your liver function by detoxifying the body, acting as an antioxidant, reducing fatty liver, and lowering inflammation.

Gut - Intermittent fasting helps improve the diversity of your gut microbes. It also helps reduce the inflammation in your gut that contributes to leaky gut syndrome. Additionally, fasting helps prevent SIBO (small intestine bacterial overgrowth).

Immunity - Fasting improves your immunity. It helps you become immune to pathogens by increasing the strength, size, and quality of white blood cells. Prolonged fasts (72+ hours) help produce stem cells—which basically helps you grow a new and stronger immune system.

Pancreas - The effects of fasting on your pancreas are huge. When you’re eating 3-6 meals a day, you are constantly triggering insulin. This creates damage to the cells in your pancreas. When you fast, you give your pancreatic cells a chance to heal and regenerate. In turn, this helps restore insulin sensitivity.

Fat - Fasting helps break down fat and get rid of fat cells. You also start generating ketones, which are a great source of energy. Intermittent fasting helps respire leptin sensitivity, which helps reduce inflammation and hunger.

Muscle - Fasting helps you restore insulin sensitivity, which also helps your ability to create muscle. Fasting also causes your muscles to go into a state where they stop breaking down—it prevents protein loss.

Heart - Fasting helps trigger the parasympathetic nervous system (relaxation mode), which is the opposite of the sympathetic nervous system (stress mode). This helps with normalizing blood pressure levels and heart rate. Fasting also helps with heart rate variability.

I’m fasting now, I’m doing 48-72 hours every week. So far I feel great slightly more energetic than usual. It’s all about willpower and commitment. Goodluck everyone

I say it all the time... fasting is the fountain of youth

There are only benefits from fasting. And the best part is you don't get hungry anymore like you used to do, when you were eating carbs. No more crashes, ups and downs. Calmness follows, super sharp mind, natural high, normalised blood pressure, fat burning effect, positive mood, lots of energy, no inflammations, better sleep, great for the heart, brain, joints all organs. What's not to like? I mean. Hello. Life is wonderful.

Another wonderful thing that people don't mention is how great food taste after you've been fasting 18 to 20 hours also your stomach really shrinks when you do omad so you can't eat more

Fasting saved my life. So thankful for your videos!!

[sunnynguyen]

I feel foggy in my mind recently so I decided to do prolong fasting. today is my second day, my mind much clearer and definitely improve the mood.

Fasting is God's gift. So are great teachers like Dr. Berg. My experience is once mitochondria are fat-adapted through keto you can fast as long as you like. Recently fasted 10-days, could have easily continued but stopped to be prudent because I'm in my ninth decade. Some of the greatest benefits from fasting are spiritual.

I love Dr. Berg's community it's so vibrant, heres to all of us in our journey to perfect health

Thank you so much Dr. Berg. I do alternate day fasting and I no longer get hungry on my fasting days. Glory to God for you Dr. Berg and your whole family!❤

I have been fasting since Sunday evening. My goal was 3 days but I fasted for 3 days last week; so I am going for 5 days this time, until Friday evening. I feel great!!

[abbeyjane]

I have been watching and forwarding your videos for almost 3 years. Short. Concise and informative. Doesn't get much better than that.

[dumisanimasilela]

After I did a 72 hour fast I realized that there's no need for 3 meals a day. One small meal a day is enough.

😅 I legit just realized that I fasted a lot as a child because we were a little poor...not poor poor you know? But meals were definitely far and in between. Don’t feel sad because I am perfectly fine 😆 momma did her best and it was nine of us and she was alone, we ate when hungry not with emotions and out of habit; I didn’t have soda until I went to college and because of that I don’t have a problem ditching soda or any sugary drink because you were lucky to get ice water because that was a big deal lol. Also, when I was little the main event was to go outside and play! And I rarely got sick when I was a child. Children now days eat as soon as they rise out of the bed with bagels, cereal and orange juice. Just making light of it but I can see why I fasting wasn’t that hard for me 😄 but the benefits are very satisfying and the more I learn the more I grow.
