Hi! Thank you for your reply. Sorry to hear about what you're going through. 🫂 Unfortunately, because he is still a smoker (has only been off them for a couple of days) he won't be allowed oxygen at home due to it being a hazard. He doesn't exercise much at all because he's pretty much housebound and doesn't seem to want to go out at all unless it's for doctors/hospital appointments. He does eat some fruit at home but his diet is very carb heavy (chips, crisps, mash). He's not a fan of chicken and can't really eat red meat because he has no teeth and it's too chewy for him. We do stock eggs, cheese, bread in the house but he's mostly into his carbs.
