you can thrive solely on eating a cow if you also eat the organs.
only cook with animal fats (never seed oils)
olive oil (never cooked) and fish oils very healthy.
vegetables are entirely useless.
the ideal diet includes fruit; i have not read any compelling argument for why carb-free is ideal. only adviseable for weight loss goals.
sugar from fruit is the ideal energy source, better than ketosis. fruit contains all vitamins you need if you don't want to consume organs.
raw is always better, even for meat. cooking is wholly negetive and no benefit outside of taste. it is destructive of essential probiotics, nutrients, makes digestion more difficult and inflamatory, and introduces free radicals (cancer causing) with high heat cooking. all that said, it's the lesser important thing. i still eat cooked. (although it is unideal, im a kept man, my wife learned to tempt me by becoming a 5 star chef seemingly.)
never consume PROCESSED sugar. (table sugar and corn syrup)
natural sugar is completely healthy and beneficial (honey, fruit)
never consume artifical flavorings, preservatives, colorants. (destroys microbiome, cancer causing)
gluten is a toxin. some handle better than others. ideally avoided entirely.
potatoes, rice, all grains, all legumes, . (ordered in least destructive to most) are to be avoided. low quality animal tier feed.
I go into great detail in all of this, among many other tenants to ideal living in my book "RETURN TO ADAM: Ideal Christian Health" available on amazon for ebook .99cents or paperback 9.99 (if you're in the states). 120 pages.
