I am not the sharpest knife in the drawer by any means. In the beginning people would say I OMAD and I would say I don't know much about that but I only eat one meal a day. Took awhile before I put two and two together. With that said, the first rule of thumb I used with carnivore was 'eat fatty meats' and the second was 'eat when hungry and est til comfortably full'. The combination of the satiating red meats and waiting til I was hungry started to curb my appetite a couple months after starting carnivore. I was OMAD before I even knew anything about OMAD. I read where some do not consider 'intermittent fasting' a thing and choose to call it 'time restrictive eating'. For me they are one in the same, like same flavor but different labels, if that makes any sense at all. Around 18-19 months eating once per day felt as natural as those years where it was natural to start everyday off with a 20oz Mountain Dew, a bacon, egg and cheese on white bread followed by two Little Debbie oatmeal cakes. Almost like a religion. Turns out I actually needed some sugar in my diet in order to have an appetite again. Just the craziest thing. Scott
