I've been navigating nutritional tribes for over 30 years now because of being delt a bad hand genetically. Been duped into the plant based narrative in the past, and went ovo-vegetarian for a few years untill I discovered new health problems (gum disease) were cured magically by just eating some duck liver once a week. Years later I found out that specific plant foods (legumes and sweet fruits such as bananas) were responsible for headaches and weight issues respectively. Like all diet tribes ever, a vegan diet is mostly narrative that pretty much breaks down when you run the data or run N=1 experiments. I'm not with the whole carnivore diet clan, but the number of people who resolve decades long health problems by eating nothing but water and meat is really telling us the plant based for health is humbug.

As for genetics, we decent from entomophagous proto-primates and we as apes diversified to also eating meat, leaves, roots, fish and fruit. And guess what? Environmental issues faced today can be solved without monocrops and without monocrop fed CAFO meat if we just embrace our entomophagous root. Read the post I linked to.

I'dd suggest we stop polluting Exyles comment section with this off topic sub-thread and move this discussion to that post instead.

Your logic is incorrect. Bananas do not cause weight gain, gaining fat is caused by eating too many daily calories. Eating a caloric surplus is what causes people to gain fat. Not all weight is equal. Gaining muscle is what bodybuilders try to do so we need to be more specific. That's exactly why so many people are having success losing fat with paleo, because if you cut out carbs, usually your total calories for the day drop. Calories in calories out, simple laws of physics. Btw, I do not support a paleo, or keto, or high fat diet, I think it is horrible for your health.

Apes eat meat and fish out of necessity not choice, since they are running out of fresh fruit and veggies, in their natural habitat. Your health issues was most likely caused by not eating a proper vegan diet. The duck that you are eating, got all the nutrients and vitamins it has by other animals. If you follow it down the food chain far enough, they are all eating plants. Show me a vitamin or nutrient that exists in animal products that doesn't exist in plants in a much cleaner form.

Was your gum disease bacterial? It could have been the antibiotics that they pump into the ducks that cured it. Hard to say, since I'm not an expert on that, but that is a possibility.
