I thought I was fine without high-protein, but it turns out I'm doing much better at about a pound a day. And it's not a struggle for me, so maybe that's a clue that it's not right for you. I can easily sit down and eat a pound or more of beef and chase it with a pile of fatty veggies without any discomfort. I do it many days a week. So it seems I am somewhat more intended for the higher-protein intake. But if it's hard for you to eat that much, maybe you aren't designed to.
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.
