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. Scott
