i've been fasting for years now, even before carnivore. skipping breakfast is pretty easy. i can sometimes skip lunch but i think my body is too stressed to do 20 hour fasts. today i tried and i actually suffered SI so i broke my fast at 18 hours. that might be the new sweet spot for me.

I think a lot of people go the 16:8 route.

I have never had insulin nor blood glucose issues (never got over a 100 til carnivore, go figure?) If the circadian rhythm is factored and the normal dawn effect with blood sugar, an early breakfast sets the tone for insulin resistance the rest of the day. For me, if I am eating breakfast I make it much later in the morning, more like lunch time.

I have read 16:8 is more effective if the 16 is from later at night til midafternoon.

Personally, I have used OMAD form of fasting, and my longest was 7 days.

I'm back on nights this week. I ate last night and will eat again this weekend, maybe Friday or Saturday.

I'm a big fan of the fast. At this point it is all about the healing and the life longevity it provides. Weight loss is just a "lil' bonus".

I been OMAD for almost 2 years. I go 22 ish hours , eat and window closes 2 hours later. I try ti be very consistent. I aim for regularity.

yes paul i'm trying to narrow my window to maybe 4 hours. OMAD is too stressful still. 16:8 makes me feel sluggish all day. i hate being at work after eating anything. i really like fasting all day. i run into trouble, though, when i eat a large meal first, then i don't feel to eat again later in the evening, making me break my fast earlier the next day. thus repeating the cycle.

I get it, my pattern just sort of evolved.

OMAD just came naturally to me in the beginning. I didn’t do it on purpose, it just happened. I had a rule that I would only eat when I was hungry. It seemed silly to eat by the clock. Our ancestors ate when they were hungry but we started eating by the clock to fit into corporate America timelines.

I now eat 2MAD to keep my weight up and to spread out my meals because as I said on another post, I would eat so much at my one meal that I would be too stuffed to get anything done.

Don’t concern yourself with eating ONAD just because other people are doing it. Do what works best for you. You’ll have less stress and feel better about your diet.

that's good advise geezy. what's weird is that i tend to gravitate towards a 20 hour fast. but eating 2 meals within 4 hours seems a little strange. i don't know why, but it's hard for me to push beyond 4 hours.

Dr. Chaffee has a video and pretty much says if you are eating once per day on carnivore there is no need to "fast". And then others don't call it 'intermittent fasting' but choose the term 'time restrictive eating'. I would guess going twenty hours apart it would not make much difference between one larger meal or two smaller meals.

And then it depends on the goals. If fasting is being done for weight loss then OMAD with 20+ hours between should serve the purpose, especially if the OMAD is the carnivore/low to zero carb approach.

The metabolic benefits require some longer fasts.

So far all the changes I have made have been relatively easy. I switched to carnivore cold turkey and didn't experience any cravings for all the crap I was eating before. When I tried fasting, I didn't have any issues going past 24, nor 48 and then 72 hours. No issues doing 96 hours and have done one 7-day water fast.

My biggest issue with fasting is how to break the fast. I have not figured that out at all. I have tried smaller meals, broths/soups, eggs, what feels like everything but fruits. (read about the benefits of melons recently but have not tried it) The first thing I eat gives me really loose stools for a day or so afterwards.

I just woke up from night shift and I am about 52-53 hours into this fast. Feel great. I had a solid lift this morning at the gym after work. Although I only slept from 10AM to 3PM I feel well rested. I'm going to lift again in the morning and then figure out when and how I break the fast from there.

Big fan of fasting. And if someone made this same post some two years ago I would think they were as full of it as a Christmas turkey. It makes no sense to be energetic and feel great from "not eating". I have found the more I read and experiment with fasting how little I actually knew about things before.
