You can tell him that all that stuff is true for people who eat a lot of carbs but carbs, themselves, are the killers, not the egg yolks or fat. I think you can send him a stack of papers linked in the ketogenic diet thread that will convey that.
Yes, I told him many times about carbs, but he just starts to talk about his blood type, he is AB and he can eat grains etc. (I don't know what blood type I am, but I know I like eggs very much and I can't get enough of them!) Two days ago he was eating his dinner and I was preparing mine, and I started to talk about ketogenic diet. I explained to him what kind of diet it was and for what is good for. He started to talk about a blood type again, and I told him that it heals everyone no matter what blood type person is. And then there was silence, he didn't want to talk about it anymore. He knows only the basics of English, so I think he wouldn't pay much attention to the papers about ketogenic diet. I guess I have to prove it that he is wrong on my own example. Grandma is the only person in the family who is open-minded
About a month ago I asked her if she would like to try cream made of lard for the face and body (translated on English it should be called "Lard washed in 9 waters"), I will make it for her and myself. She started to laugh and said "Sure! Why not!
" That's why I love her so much
