    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&apos;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&apos;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! &nbsp;I&apos;m definitely trying this! &nbsp;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&apos;t want to fast for 7 days but also don&apos;t want to pay for expensive BHB. &nbsp;It was my attempt to recreate a sardine fast without the sardines as I can&apos;t tolerate them due to histamine intolerance. &nbsp;Anyway, this was my protocol, basically a fat fast. &nbsp;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. &nbsp;I would lay off the MCT by 2pm so that it didn&apos;t interrupt my sleep but continue the EVOO until bed. &nbsp;Important note: don&apos;t buy the garbage sold in regular grocery stores. &nbsp;The olive oil has to be single origin high quality olive oil. &nbsp;I get mine from olive oil lovers (no, I don&apos;t get money for recommending them!) &nbsp;But Costco has a few select offerings (bland in my opinion but still real olive oil). &nbsp;Lots of videos on youtube about how to tell if the olive oil is real and not mixed with seed oils. &nbsp;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. &nbsp;By mid day on day three I am in the 4 range. &nbsp;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. &nbsp;Not sure if it is a cortisol issue or what. &nbsp;But I usually break the fast at that point. &nbsp;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. &nbsp;An hour later, bone broth. &nbsp;This absolutely recovers my nervous system and the anxiety stops. &nbsp;Incidentally, (and don&apos;t yell at me if you think this is a bad idea), I also use chatgpt to guide my fast....it&apos;s more mental than anything! &nbsp;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. &nbsp;It&apos;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&apos;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. &nbsp;It started at one day, to see how I felt. &nbsp;Felt fine, so kept going to three days, and so on to ten days. I had water, coffee and tea. &nbsp;I did a few fasts in my thirties and wish I kept it up. &nbsp;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. &nbsp;I did not weigh myself before or after, because I&apos;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. &nbsp;(Big Mac + Large Fries + Large Diet Soda + Large Payday candy bar). Ended up in the ER. &nbsp;Symptoms were extremely low blood pressure, and a heart rate of 132 that lasted for 2 days. &nbsp;Ended up having to get an electrolyte IV. Lesson learned.

    Something not mentioned is what happens in your mouth. &nbsp; 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.

    That was the longest commercial for that keto supplement ever.
