In this video course Dr. Jason Fung lists the 5 top myths about fasting – and exactly why they are not true. Are you going to lose a lot of muscle? Suffer low blood sugar? Or enter the dreaded “starvation mode”?

    Jason Fung says in his book „The obesity code“ that you don’t get tired when waterfasting, you actually gain energy. Then why is it that I am getting tired and a kind of brainfog when fasting? On day 4 now. I have watched a lot of YouTube videos on waterfasting and a lot of people tend to suffer from feeling weak and tired when fasting.

    You may wish to incorporate bone broth for the electrolytes.

    I am 77. I started fasting on 24-04-2019 at 5-30pm. It is 16 /8. 11 days ago I started to do push up for 2 days with a rest on 3rd day with 20 in a row. Now I am able to do 55 push ups in a row in fast window i.e in the morning. I could do 1000 push-ups on 25th of this month in 40 sets. Previously I was able to do 30 bench dips. Today did 50 bench dips in a row. It is a result of water-fasting 16/8.

    .

    I do not have any research or information indicating that keto would be a bad idea. If you are a kidney transplant patient, please work with your nephrologist on your protein needs.

    Bone broth breaks the fast.. and the autophagy. It takes a few prolonged fasts to get used to it. After the brain fog, you will get a ton of energy. The more toxic your system is, the more brain fog as well. There's also the factor of switching from glucose to ketones. Etc. You'll be fine, stick with it.

    Definitely sounds like you need more electrolytes if you’re a long energy and having brain fog.

    I fasted for 2 days. My mind was great day 2. noticeably sharper. I just ate lunch day 3 and feel terrible. Not the most scientific but I am going to try a longer fast. I need to drop 30 lbs fat so worry of starvation.
    Finding it weird how hangry I usually get and today I really didnt care if I ate lunch or not ... but did to see what would happen. Not good. I feel hungrier now than before eating and my brain has slowed down.

    I'm on day 3 of water fasting. Just hit 73 hours of nothing but water in my system, yet still feel bloated, haven't lost a pound, and haven't gone to the restroom except for urine. Is this normal?

    For any fasting over 36 hours we recommend consulting a medical professional. Please find our fasting guide with more information here: https://www.dietdoctor.com/intermittent-fasting
