I have read his book The Great Cholesterol Con ChaChaCha2012 and I believe it's based on sound science. I see this recent paper says similar
It's not. He had a 2016 paper ripped to shreds for only choosing studies which supported his idea that cholesterol doesn't cause heart disease and ignoring those which do not.
A lot of his statements about how terminology is often poorly communicated to the public are true; but the idea that the experts in disease control don't know the correct termionology and are basing all their predictions on one model which used a wrong number from a jounal is laughable.
I could pick apart where he also mixes up terminology in the article, explain the information he doesn't say and list every bad faith assumption he makes, but none of that is the point:
In Science we reach conclusions by evidence and peer review. We listen to the consensus of the experts in the field- not one outlier with no expertise in epidemiology. Many early predictions about Covid-19 will change, the people making their best guesses know that. Still the idea that they are all completely wrong and this GP is right is just silly.
