Nutrient Density of Animal-Sourced Foods: Animal foods pack a nutritional punch not found in plant foods, offering essential nutrients like vitamins A, K2, B9, B12, B6, D, heme iron, and omega-3 fatty acids. This makes animal products both qualitatively and quantitatively superior, providing nutrients in forms readily usable by the human body.

Gut Morphology: The human digestive system, characterized by a smaller colon and a longer small intestine, is optimized for the digestion of fats and proteins rather than fermenting plant fibres. This adaptation suggests a dietary shift towards energy-dense, nutrient-rich animal sources, reducing reliance on plant fibre.

Bioenergetics: Humans require significantly more energy than most primates due to our large brains, extensive tool use, prolonged child care, and learning activities. Meat provides a more efficient energy source than plants, offering a higher energy return for the effort expended in hunting compared to the continuous gathering of plants. This efficiency in energy acquisition likely influenced early humans to favour hunting, especially during periods when plant resources were scarce.
Diet Quality: The human brain is exceptionally large, necessitating a diet rich in high-quality, calorie-dense foods. Animal fat, being more calorie-dense than proteins or carbohydrates, playd a crucial role in meeting these energy demands. Plant-based diets often contain antinutrients that can inhibit nutrient absorption, making animal products a preferred source for supporting brain development.

Theres diffrent types off fat, animal fat from steaks, like the the fat around a sirloin steak, and the fat in a ribeye steak, and mince steak meat i always get 20% fat in it, full of flavour and goodness, fatty streaky bacon, then u have man made saturated fats, greese now when talkin off fats have too rember there diffrent types off fats, animal fast that u get in animal products is good for u full nutrion and flaour, and my sister is on the carnivore diet has been for just over a year, eats no carbs, before she startes it she has loads pains, tennis elbow inflamed joints ect, all gone now and she trains in gym and her physique is amazing, shea has ate carbs few times to test a thsory and every time she eats carbs her pains come back, alot off carbs cause inflamation in joints, theres loads off facts proving this out there, she dosent get food cravinga anymore, and is fullwr more eats less, as the meat keeps u full longer. To be onist im sick off hearin about steaks and meat the damn lectures she gives me about it ffs --‍♂️ if i even look at a carb or bun shes at me ( thats not food why would u put that in ur body ) bla bla bla --‍♂️
