It's an interesting video and he seems credible - though I bet there's someone else with credentials who could argue the opposite. It's difficult not knowing whom to believe.
But I think there is a bit more to it than just 'eat more salt' or all fats are 'protective'. Of course this might not apply to everyone equally.
I must confess I still struggle to accept that sat fats are healthy to it in lchf amounts. I cannot shake that off - and I know what my gp would say too!
In fact a friend of mine was diagnosed with type 2 a few months ago and he went to a healthy eating class provded through the nhs. They taught him the conventional wisdom: low salt, low sat fats, etc. He's lost 16kg in 3 months. What can I say to that? I said nothing of course, I'm not going to tell him what he's doing isn't working, how could I prove that? Meanwhile I'm on day 16 of LCHF and haven't lost a single gram.
Not trying to focus on me, btw. Just making the point
