You continue to conflate fat and meat and then make points implying that meat consumption is fine.
I don't see how controlled studies are possible for various reasons. For starters there are far to many variables and we have no idea how they interrelate. Second, we can't control humans to the degree that would be needed to truly isolate a single variable (which I don't think would be too useful anyway) and animal studies are always imperfect. I'm convinced that diet studies are most effective when performed at a higher level of abstraction.
