Im not sure the wiki is helpful, except to demonstrate that disinformation is alive and well, especially when trillions £££ are involved. A group of Drs were chatting about that wiki entry the other day and the utter ridiculousness of it, he must be really annoying those with £££ interest now, other factual stuff has been deleted. Have a read of his work, it’s easy enough to check the evidence and follow the published research studies, he is an intelligent and ethical Dr who has always been happy to debate with his peers. None of this should take away from the message that lifestyle changes can have a very positive impact on your health.
