Help husband lose weight?

Posting again because I was so long winded

My handsome, sexy, overweight husband has family heart problems that obviously being overweight puts him at risk for.

1. I'm a little overweight too but disabled and can only occasionally swim, which he has no interest in.

2. We already eat pretty healthy and I cook everything from scratch (food restrictions).

3. He so has self esteem issues. Idk how to bring this up stronger than I have without hurting his feelings. Hes stocky and strongman build, I feel strength training would be a good fit. I used to be a workout nut during remission but he never was interested in working out. I just want him healthy and happy.

Help?

[Edit/update: yes I'm slightly overweight, I could eat less but I am a stable weight for the last several years. My main issue is inconsistent eating due to fatigue (puts your body into starvation mode and holds onto weight) if I prepare better and graze more I know I'll lose weight. I've done it in the past, but my doctor is not concerned with my weight, he says its average for those with my condition and my losing weight too fast can trigger my condition. For him (husband) I think its lack of self control and working near a place where he can buy whatever he wants to eat. I only have control over one meal, two if he remembers to bring his lunch]
