Meat is not bad on its own. All claims and 'research' about meat being bad are by people who have an ulterior motive. Online it's mostly sensitive vegans who think that the legitimacy of their goal of 'not hurting animals' gives them right to steal, cheat and kill their way to it.

All bad things related to meat consumption are result of intensive and unhealthy farming practices, and combining increased fat intake with increased carb intake (especially fructose). Correlation, not causation.

That being said, there are two issues with meat: in the West, we pretty much only consider muscle as meat, and dislike the internal organs, when it should be the other way around. Even obligate carnivores prefer internal organs because they are richer with fat, and often leave a lot of muscle meat on carcasses.

Second, and related, issue is that muscle meat based diet is a high-protein diet, not high-fat diet, so it's more akin to Atkins than to keto diet. High protein diet comes with its own set of issues: it places significantly higher load on liver, which causes increase in liver size; obligate carnivores have extremely large livers compared to their body size (just google for an image of shark's liver compared to its body, it's almost 1/3 of the volume). This also applies to humans, for example Inuit have enlarged livers as well.

This is the result of increased need for protein-processing capacity. Liver can only process so much protein into fuel per unit of its volume per unit of time. And to use Inuit as example again, because of this, they keep snacking every couple of hours, more often when exerting themselves physically.

A related concept is 'rabbit starvation': eating lean meat (rabbit in winter) is not enough to keep a human being alive - while you're in theory ingesting enough calories to survive, your liver's capacity to process pure protein into fuel is less than your body's need for fuel.

[1] gives direct evidence that meat from grass-feed cows comes with higher load of endotoxins than wild game. It will be interesting to know if this is a consequence of modern breading/farming or something related to cow domestication.

Thank you for that link.

The summary doesn't mention 'grass-fed', only 'wagyu'; wagyu is intensively grain-fed in the last year of their life or so.

To quote from a quickly-googled article:

"What many people overlook is that farmers make Wagyu as fatty as possible by feeding their cows huge amounts of grain for the last 300-500 days of their lives. Some farmers even add wine and beer to further increase fat content. The result is that a wagyu cow’s muscle tissue is thoroughly marbled with fat. Unfortunately, it’s the kind of fat that is not good for you. The mold toxins in all that grain are bad for the cow and end up in its fat, and then in you, which would mean wagyu beef has a disproportionately high toxin load."
