Yes, you have it right. I eat as much as I want of Primal foods I like - most of the time. And lost 50 pounds doing just that! This was my first "diet" and I don't think I'd have touched it without the caveman label. It's kind of extreme, odd and fun, and scares boring people. I need to scare boring people to feel alive.
Liver fixed my lifelong malnutrition. I was a macaroni and cheese kid and rarely had real meat. So by my 20's I was falling apart, and my head was full of incorrect nutritional notions. I thought bready food had everything I needed (TV told me so, and my family knew no better, povertous folks), but since I was still hungry, I clearly needed to eat more, because the cravings were so strong. So I'd eat an entire pizza and a box of twinkies and have two sodas and just keep eating, eating, eating. Cutting those out helped, but I still wanted to eat - everything. It was like mild pika. Then I tried increasing my (good, real) meat, and that helped. But the liver finally hit the spot. Once I had adequate B vitamin intake (and all the rest, you know how amazing liver is!) my intense cravings finally went away. Whether I was B12 deficient or what, I'll never know. I never had labs done back then. But I lived on Taco Bell, Pizza Hut and soda. Everything I ate back then had a brand name and a half-mile of ingredients. I can promise you I was vitamin-deficient in a huge way.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
