Nothing wrong with meat. The problem is the processed food industry and anti-meat fanatics preferring everyone eat something other than animals. Nope, give me my bacon, steaks, fish, and so forth. Cholesterol is fine, health is fine.
If meat was bad for mammals (yes we are mammals) then tigers and lions should be dropping dead of heart attacks at early age. Instead they are strong like hell.
The problem with humans is not meat, IT IS LACK OF EXERCISE.
