My father just had a heart attack, caused primarily by red meat and stress (as he's already living very healthy except for these two factors). The current recommendation is down to 50g a day. If we look at how prehistoric humans actually lived, we can take a look at today's remaining hunter-gatherer societies. Most of which eat up to 15% of their daily energy intake as meat. The fossil record shows similar patterns since before the emergence of homo erectus, so we can be reasonably sure that this value is relatively consistent over time. Hunter-gatherers primarily ate meat from small mammals, fish and poultry. If we use the nutrient values of rabbit meat, this would be equivalent to about 200g of meat per day per person, so a rabbit could feed one person for 5 days at least. Realistically, it would be significantly less than that, as most hunter gatherers had access to fish and poultry.
