Often, people want to feel like their making their own decisions and what one side thinks of as helpful advice is viewed as 'orders' or 'railroading' by the other and there is resistance. Perhaps lead by example and don't say another word until he's so curious he's busting to ask and then resist the attempt to download, just present relatable 'breadcrumbs'. Could you keep your stats daily on the fridge? Just for yourself you understand and make him feel a partner by asking him to help you without any requirement to join your endeavour. He may feel overwhelmed and powerless.I don't think a GP is allowed to discuss a patient with someone else without their consent.
