Just after some advice how to approach this with my partner as I don't want to push him away but am so worried for his health and our future. Sorry it's turned out a bit long but didn't want to drip feed.
Been with my partner 5 years, getting married in 2027, we are both mid 40s. We both want a long future together.
He's grown up on a childhood diet of beige sugary, fatty food and fizzy drinks. Was very overweight as a child and has since slimmed down a lot but still 18 stone now. Between leaving home and when I met him, he lived on the same ( he was previously married so not living as a typical single bloke eating convenience food, but they did live on convenience food). He doesnt eat fruit and veg if he has a choice but still just eats high calorie, high fat high sugar food and drink every day. We did a quick tally up once of a day's food and drink (which he said was a good day as he'd 'cut back'). He'd eaten no fruit and veg, had 3 cans of pop and overall the equivalent of 250g of sugar in 12 hours!!!!!
I can see him starting to get health issues and he's recently lost a few teeth due to the sugar and fizzy pop eroding his teeth. (I have finally got him to book a dentist appointment).
He says he enjoys his diet and it makes him happy and he's always eaten the same and been fine with his health. I've said it'll catch up with him now I to his later 40s.
I've tried to talk to him about healthy eating and he does eat what I cook him when he's with me and enjoys it (we dont live together yet for logistics reasons with work / kids schools) but he refuses to see there's a problem with his diet and the impact on his health.
I know he's an adult and it's up to him what he eats and how he looks after his body. I don't want to be a nag or controlling over his diet as it will push him away. But we have so many plans for the future we want to have together and I'm so worried he'll die young if he doesn't change. But he won't accept there's anything wrong with his diet. I just don't know what to do and I'm scared for my DP and our future.
Please don't tell me to leave him due to different outlook on health as everyone does on MN, he's an amazing kind wonderful man and the whole point of this is that I don't want to lose him either through poor health or by pushing him away.
For added context, my DC's dad died young at 49 due to bowel cancer from a very similar poor diet - so I've seen what can happen (My DP is aware of this fact but thinks he's different).
