Curious what's your diet like and why you are even inquiring about the carnivore. For me it is medicine. Earth medicine. Not pharma symptoms covering medicine while making you sicker.

Many reasons, but most important health. There are some things bothering I guess mostly related to stress/anxiety. Doctors I don't trust.
Apart from that, I love meat. It's fast to cook. Not much to clean after. Efficiency:))
But right now I'd eat an omelette for breakfast with about 300-400ml of beef broth and like 40-80g of dried beef. Rice cakes+butter and some type of cheese. Then I'd eat some fruits. And dinner is steak, salad and maybe rice or bulgur, walnuts.
That's it.
And coffee, mornings only.
