Nah never went full carnivore, but I've been "paleo" (or something basically that) for a really long time. Meat and animal fats are certainly my dominant source of protein and energy. When i deviate i notice it very quickly too. A couple of days eating like crap and I pay for it quickly. I always end up going on a steak cleanse to get back to baseline, lol.

My diet staples though are bacon and eggs, steak, lots of fruit, some grain free "breads" from time to time, almond milk/butter (occasionally), sweet potato, and some sort of yogurt on occasion.
