Well done documentary that had me...then lost me. The practical research that was done was pretty eye opening. But then again, so was the research done on the paleo diet when it hit. The way this documentary was done seems like it sucks you in with a lot of facts, then once you're hooked, that's when all the liberal politics get thrown in your face. It almost goes from sports and diet documentary, to a PETA infomercial. Would've been great if not for that. It came across as sneaky.
