It does not matter who he is talking too what he has explained so far is misleading at best and more like outright misdirection and lies. If you take what he has said in the first 7 minutes is that vegetable based oils are bad, trans fats from vegetable oils are bad, grain and process foods fried in trans fat filled vegetable oils are bad. All of which I and everyone else here agrees with. A clean diet is the way to go but he has not made any point that confirms meat eating is bad.
The links below your latest video are all to abstracts and the third abstract states " These results suggest that dietary protein and soy isoflavones, in the context of comprehensive lifestyle changes, may not significantly alter IGF-1." So no real difference with regards to the type of protein intake and I would rather eat my grass fed hormone free beef than GMO soy.
TBH one of the biggest problems with meat eating is that mass farm meat eating is grain based, and full of antibiotics and hormones...prob a bigger factor than anything else out there.
Actual full studies would be much more productive.
Eating primal is not a diet, it is a way of life.
