2 months out from my wedding and the fiancé is still eating completely unhealthy.

Fiancé is 25(male) 165lbs 5’8” on the skinny side due to being 350lbs 2 years ago. He’s gained 30lbs in the last 6 months. Is 240lbs his ideal? No, he’s said he wants to lose 40lbs of body fat and gain muscle. Thing is, eating 4 slices of bacon and drinking a pint of cream for breakfast (daily) isn’t going to help him get there. He goes to the gym a few nights a week, but still isn’t making healthy choices. He’s super unlikely to do meal prep so I just want him to be healthy and not have clogged arteries. He’s said since he’s not overweight, it’s fine. 2 months out from our wedding and a year out from our honeymoon, I don’t want anything to happen to him. I just want us to live a long healthy life together. Any advice on how to approach him? I’ve said my piece and now I just need to let him live. I’ve also told him I want a wedding night to remember, and I want him to be healthy for our future kids.
