Ok, not morbidly. He's 5'10 and 14 stone with a huge gut, moobs and love handles and frankly I don't fancy him. He's 38.
I've tried saying things jokingly, putting us both on a diet, I bought scales to have a challenge of who can lose the most. He sits down with this giant gut and it's gross. He's got a hugely sweet tooth so tried not buying treats but that's unfair on the kids. Very occasionally he'll run or play golf but never weights or abs stuff.
Bottom line - I don't fancy him at all.
