He is putting lives in danger.
I think that the most dangerous thing is that (IMO) Dan Wheeler honestly thinks that he knows what he is talking about. He is a narcissist - he can't even contemplate not being the authority on absolutely everything.
Remember when he came back to that lady on TT who said she was following Dr Greger and he straight faced said -"I've also studied this most of my life as well" - I mean it's embarrasing. Nothing wrong with looking in to things on the internet, but you can't equate that to years of medical training and a research team at Cornell. That made me realise that he actually thinks he is as acomplished.
There was a live he did recently and Dan Jones joined in and he said he was aiming to get to a certain weight to do a dexa scan and the Dan W said we need to get you a blood test to see if you still have diabetes
Now I'm no doctor, but I really don't think either of those things are going to show the results you think they will! Look at DJ's holiday tiktoks - he is binge drinking every day, the food looks horrendous, there is not a vegetable in sight and he looks as big as ever - not to mention he is badly out of breath when he walks. I think any responsible person would not have used DJ as a project. He has spoken about his serious health issues, including sleep apnea and almost dying. This man does not need a lifestyle plan -this man needs medical support and shouldn't be disuaded in the way that he has been to overlook doctors advice.
