Completing a workout before starting to help deplete glycogen stores before embarking on your 24 hour plan helps speed up ketosis as well.

Intermittent fasting wrecked my hormones 😔 I tried the long fasts everyone raves about and my sleep got worse, my anxiety spiked, and I felt shaky all the time. Thought my body was just broken. Then stumbled on Menopause Transition Playbook written by (Lisa.Grant) in a women's health thread and realized I was doing it all wrong. Now my body responds so differently, 28 lbs gone, mood stable, and those awful sugar cravings disappeared. More women need to know fasting isn't one size fits all.

I used 3 seven-day fasting to create a tolerance towards alpha-gal antibodies within eight months I was able to have all mammalian derived foods. That was 2 years ago and still going strong.

Thanks Nick! I'm definitely trying this! Also, I found a way to get my ketones to 4 and above with just a 3 day fast. May be a less expensive option for those who don't want to fast for 7 days but also don't want to pay for expensive BHB. It was my attempt to recreate a sardine fast without the sardines as I can't tolerate them due to histamine intolerance. Anyway, this was my protocol, basically a fat fast. Days 1 and 2, I would have 2 tsp of real olive oil plus a few MCT oil capsules every 2 to 3 hours while awake. I would lay off the MCT by 2pm so that it didn't interrupt my sleep but continue the EVOO until bed. Important note: don't buy the garbage sold in regular grocery stores. The olive oil has to be single origin high quality olive oil. I get mine from olive oil lovers (no, I don't get money for recommending them!) But Costco has a few select offerings (bland in my opinion but still real olive oil). Lots of videos on youtube about how to tell if the olive oil is real and not mixed with seed oils. Anyway, by the evening of the second day, my ketones are hitting 3 to 3.5 and by that point I stopped the olive oil and MCT and just did a water fast. By mid day on day three I am in the 4 range. Ive continued for a full 4 days but have found by then that my nervous system is off the wall, felt super anxious, unable to sleep etc. Not sure if it is a cortisol issue or what. But I usually break the fast at that point. I also actually spend two full days breaking the fast...the slower the better. I always start with 30 Recovery Bits which coat the lining of the gut and prevent any unfortunate gut issues. An hour later, bone broth. This absolutely recovers my nervous system and the anxiety stops. Incidentally, (and don't yell at me if you think this is a bad idea), I also use chatgpt to guide my fast....it's more mental than anything! It helps me to keep going and I have found it really guides the breaking of the fast in a controlled way that prevents refeeding syndrome and maximizes the benefits. It's like having a fasting buddy cheering you on!

I used to do a 6 day fast once every year. I am a thriving survivor of aggressive CLL/SLL and oligometastatic prostate cancer diagnosed in late 2018 and have had only 3month depot shots of Lupron (ADT) as a therapy for the PC which I paused in Dec of 2025. So far so good. During Cancer years and chemo with the leukemia I did periodic 4 day fasts every 2 months. I gave up fasting two years ago because of muscle loss ( I am now 83) While I attribute fasting to the lion's share of my success I was getting muscle wasting from years on Lupron so I chose to suspend fasting. not sure how to handle this dilemma. Have gained back some muscle and feel much better at 7+ months off Lupron. fascinating video!

Great video, as always !We have to talk more and more about fasting beyond fat loss . It makes small people be afraid of longer fasts and people who lose all the weight ( and regain it cause they don’t change their lifestyle ) gain the weight back. I’ve been fasting since I was 17 ( 45 now ) not for weight loss , in 5.1ft 100 lbs. I’ve done multiply 7 day fasts , shorter and I do 18-20 h daily , so many benefits !!!!! Mental , emotional, spiritual !!!

A few weeks ago I did a ten day fast, no problemo. It started at one day, to see how I felt. Felt fine, so kept going to three days, and so on to ten days. I had water, coffee and tea. I did a few fasts in my thirties and wish I kept it up. The ten day fast really helped a knee that has been bugging me for two years and only getting worse, my sleep is better, too. I did not weigh myself before or after, because I'm interested in health not weight.

I gave myself refeeding syndrome a year or so ago, eating too many carbs, too quickly after a 5 day fast. (Big Mac + Large Fries + Large Diet Soda + Large Payday candy bar). Ended up in the ER. Symptoms were extremely low blood pressure, and a heart rate of 132 that lasted for 2 days. Ended up having to get an electrolyte IV. Lesson learned.

Something not mentioned is what happens in your mouth. Plak starts to go awry and how “clean “ your mouth feels which gets rid of the bacteria that effects your heart and body health

If you start the fast already burning fat (keto/carnivore) it seems you would get max benefit sooner than 3 days.
