It is not a pyramid, it is simply a ratio, of 100g lean red muscle meat to 35g animal, per meal. With 3 portions of organs per week and 100-200ml bone broth and marrow per day. This is the optimal paleo-ketogenic lipovore diet that we evolved with for 2 million years to become what we are, as we hunted all the fatty megafauna to extinction and turned them into Ferrari brains.

This is highly debatable, although protein based diet is highly encouraged, come to think about it for real.
Do you think meat was 100% available for those couple millions of years you mentioned? Perfect abundance for that whole period? Also no individual would have ever decided to eat a ripe and delicious mango ready to be consumed? Bananas? Consistently turning down all fruits?
Highly unlikely. There are cycles and seasons, variety in diet makes the most sense. Meat based for sure, but throw in some fruits, berries, honey, nuts, etc for those hard times or just to spicy life up.
Throwing in fruits and eating high sugar mangoes and bananas would have been fine for people living 1,000 years ago, who had excellent metabolic health but today in the western world only 7% of us are metabolically healthy, meaning we are insulin resistant (prediabetic) and inflamed from consuming too much sugar and processed carbohydrate. A carnivore diet, in the absence of all carbs, will heal type 2 diabetes and insulin resistance.
