How should I tell him??

My amazing handsome boyfriend is a few pounds shy of 300.. after he eats he sweats for hours. He eats vegetables but butters them up. He only wants to eat once a day.

He failed a physical once before because his blood pressure was high after drinking a Gatorade. I make sure I keep waters and juices in the fridge. He barely drinks soda now but he’s not eating sweets like CRAZY.

Every time I bring him up a “health question”

As he calls them he just shrugs me off. He told me that he feels fine. He’s not rude about it but I can tell it makes him uncomfortable.

How should I go about starting a conversation with him about it? I don’t want to hurt his feelings but something has to give
