No, I hadn't watched those videos before. I've watched them and they seem to be a mix of things I know are facts and things that sound true but presented in orders and combinations that seem designed to imply certain conclusions. I find the style of the videos rather irritating, speeding up and slowing down, sitting in a medicalish office, and I'm particularly amused that "Frank Cooper, ND MANTA, BHSc (Comp Medicine), Adv Dipl Appl Sc, Dipl Nutrition" on the end titles gets much less screen time than the simple "Melbourne Australia 2011" caption!
So, let's consider this more closely: Frank was diagnosed at 25, whereas I was diagnosed 14 or 15 years younger than that, following cascade testing of my family, so he's not been studying this much longer than I have - maybe 5 years. His primary qualification seems to be nutrition, while mine is in a different allied health profession. After that whoosh of qualifications in the video end title, I looked for his book "Cholesterol and the French Paradox" and found that it's a self-published ebook. His cholesterol levels are higher than mine but lower than some of my relatives. Given all that, it's not much surprise that I already know most of his arguments, but I know there are also alternatives for some of them which he's not presenting.
Maybe I missed it, but I don't think Frank mentioned in the videos whether he has FH or some other sort of hyperlipidaemia - are you sure it's FH? His attitude to family history in video 5 seems quite dismissive, while in video 6, he criticises statins for damaging the liver, which makes me think that his liver maybe wasn't already dysfunctional (while it is in many FH sufferers).
What would be interesting is if Frank's put his body where his mouth is and both taken an alternative approach to his own hyperlipidaemia and monitored the effect with CT scans and so on, but he's not talked about himself much. He put forwards wonderful case studies of the negative effects of things he disagrees with, but not so many positive cases of successes of his preferred approaches - only chelation therapy stands out for that.
In my case, I had xanthomas before treatment and gradually lost those during medication. Whatever else I may need to treat (diet, exercise and other things Frank advocates and I broadly agree with), getting rid of those lumps seems like a benefit.
I have asked a few years ago and I was told that genetic testing wasn't used much back in the 1980s, but the cascade testing results and family history (young heart disease deaths) seem pretty strong indicators, so unless something new comes up, they won't do it.
