Today, we’re going to examine the amazing benefits of fasting. Not only is fasting the most powerful thing you can do for weight loss, but it’s also an effective natural remedy for countless health conditions. Fasting addresses the deeper root causes of many health problems: insulin resistance and mitochondrial damage.

Intermittent fasting activates growth hormone and lowers insulin, allowing you to tap into your fat cells. If insulin is high, fat can not be utilized for energy.

One of the best indicators that intermittent fasting is working is that your appetite will go away. Fasting also offers cognitive benefits. It eliminates brain fog and improves focus, concentration, and memory. It also elevates your mood and improves the immune system.

Fasting is not starving! Your stored body fat provides energy while you’re not eating. The average person has over 100,000 calories of stored energy in their fat cells.

Prolonged fasting involves fasting for a couple of days or longer. Prolonged fasting helps generate stem cells for your immune system. It also puts your body into autophagy—a state where it cleans up old damaged cells, recycling them into new cells.

Fasting repairs your metabolism—it doesn’t slow it down. It also gives the digestive system a chance to reset, resulting in less bloating and less inflammation in the gut.

Follow these steps to start intermittent fasting:
1. Go on a low-carb diet and eliminate snacks
2. Gradually push back your breakfast until your first meal is around lunch-time
3. Establish an intermittent fasting routine that allows for at least 18 hours of fasting

Once you’ve established an intermittent fasting routine, periodic prolonged fasting can increase benefits.

    I healed a severe, asthmatic histamine intolerance by IF and prolonged fasting in about 5 months. I’m still healing (my rosacea is almost gone meaning my gut is about “there”) after 13 months total in this lifestyle. Almost healed, but certainly never “done” with fasting – I LOVE IT! 52 and in the best shape of my life. *Thank you, Dr. Berg for all your critical guidance on my journey!*

    I’m definitely an advocate.
    I feel great and have lost 26 lbs and all inflammation on keto/carnivore + intermittent fasting. My fasting window is usually from 2pm-8am. Most days I’m only OMAD & seldom feel hungry. Lots of water.

    Thanks, Doc!
    I’m 63 now and started intermittent fasting and a ketogenic diet in July of 2023. I’ve lost 60 lbs so far and feel fantastic. My allergies are gone, and my joints feel better. My wife started after seeing me loose 20 lbs. She has now lost 35 lbs. We tell everyone about this lifestyle change and about your site!

      @ThisIsNuckingFuts  I do like my whiskey, and I do enjoy a dram or two every so often. However, I did wait until my body started healing itself from all the garbage (sugars and grains) I had been eating. Now we enjoyed the holidays and ate whatever we wanted, but to tell you the truth. All the carbs and sugars made me feel lousy. I feel so much better now I’ll never go back to eating the way I use to.

    • @jackrodosta7971 on January 16, 2024 at 2:46 pm

      @mattlacasse5828  exactly right! We don’t feel like we’ve been dieting. It’s simply a change in what we eat and when. No more sugars, grains, seed oils. We’ve added fermented foods and vegetables to all my BBQ 😆. I realize now, what we use to eat was poisoning our bodies. Dr Berg can’t say this because he’ll be canceled, but I can. The FDA dietary guideline are a lie! Bought and paid for by special interests in the food and pharmaceutical industry.

The sugar and the chemicals in the food really mess with the mind! Abstinence really is the key for me !

I would like to add that the I still take fiber and supplements and heavy cream in my coffee with prolonged fasting. Also, I add probiotics during fasting to keep the gut biome alive and healthy.

    I started my fasting journey 2 years ago. I also exercised (because we all should to some degree no matter what), but it helped me shed a lot of weight fairly quickly, and I omitted the refined carbs in my feeding windows. I will also say, last year, I did a 21-day clean fast, and it helped correct some of my sight in my left eye. Starting is TOUGH because we are used to expecting food, but once you get past that hump (for me, it’s the first 24 hours of major struggling), it gets easier. It changes how you perceive food. Keep up on the (pink Himalayan) salt. You just feel better all around…physically and mentally. Absolutely worth it.

    • @Silence_between_waves on January 16, 2024 at 5:01 pm

      The body needs iodine , himalayan salt doesn’t have iodine .. and it has nearly as much sodium as regular table salt . I use it for flavor , but not anymore ..

    • @helenward77 on January 16, 2024 at 5:27 pm

      @Silence_between_waves  Hi! The body needs all kinds of things that it isn’t getting while fasting. The feeding windows replenish any missing nutrients. Himalayan pink salt has a lot more minerals, and I personally think it tastes better than regular table salt. 🙏

  13. @shemj897 on January 16, 2024 at 3:10 pm

    I am on week 2 of my intermittent fasting and it’s doing amazing things to my body already. My eating window is from 1pm-7pm (6 hours). In the mornings I have loose leaf herbal tea without sugar and water until 1pm. At first I get hungry but if you ignore that hunger you can last until you are ready to eat. I really emphasize protein and less rice…I feel less bloated and I feel more alert. I strength train 3 times a week and have a cold shower after each work out… trust me, you don’t need coffee after a cold shower, it instantly wakes you up.

    You don’t need to go on all these fad diet. Just intermittent fast and eat less carbs..

    Currently on 34 fasting hours of a 21 day fast. Completed 20 water fasting days in 2023 and only reason I had to stop was because I did not have enough electrolytes. I learned that the first two days are extremely tough because your body is fighting against you but just push through and the hunger honestly goes away and you feel really good 🎉🎉🎉

I love it 44 and in the best shape of my life I feel fantastic. My mom 67 started after seeing me loose all that weight. She has now lost 8 kg. (17 pounds).

  16. @ENetworkX on January 16, 2024 at 3:50 pm

    I can’t begin to express how grateful I am to have found your channel a little over a year ago, Dr. Berg! Your videos and the information you provide has truly saved peoples lives; mine included. My eating window is exactly the same as you mentioned in the video; 12 PM – 4 PM. I cannot believe how amazing I feel during my fasting period. Working out during intermittent fasting has also been way more beneficial for growth, endurance, energy and much more.

    Transitioning from my previous lifestyle to fat burning did take a few months, but once I adapted, I couldn’t believe how clean fat fuel felt. I follow a Ketovore lifestyle and for the first time in my life, I feel youthful. Growing up, I was influenced by tons of wrong eating habits and terrible ideology. The saying was, “you’re young, so you don’t have to worry about what you eat”. That’s just as horrible as the “everything in moderation” approach.

    Have you ever wondered why Keto/Ketovore and intermittent fasting get such bad press? It’s because it works and most of us know by now that many food industries have an agenda and do not want us to be healthy and live long, happy, prosperous lives. If you are paying attention to everything around you, you’ll know for certain that I am not lying. What I told you is not a “conspiracy theory”; it’s the truth.

    I am 41 years old and have started my intermittent fasting journey since August 28th, 2023 when I weighed 350 pounds. I now weigh 265 pounds and I’m loving it. I fast for about 23 hours a day, and I follow the healthy ketogenic diet. There are about 14 other educators at the university where I am employed at who have been encouraged to change their lifestyles after seeing my results. Thank you Dr. Berg for all of the valuable information that you share.

    P.S – I also do NOT have a thyroid gland since 2022 and that hasn’t prevented my progress

    My T3 actually went up quite a lot when I started low carb/IF and exercising more. Was a little worried Graves’ disease was on the return (at that time, recovered for about 7 yrs). But within 2 months numbers went down again and stayed that way, being only slightly higher than before, but in a good way!
