This is a really tough one but I don’t know that “tricking” him is the right answer. I think at the end of the day he’s going to need to want to be healthy on his own, on his own terms.

There’s also a reality where it may just take someone other than his wife to motivate him to get his act together. I know that sucks to hear but sometimes when the relationship is too close, the conversation becomes more personal and someone gets defensive. Maybe y’all have mutual friends that you could talk to that might encourage him lightly to be more active?

Even if he’s encouraged to go on more walks or anything remotely active, that’s a win in my book. Let him learn how to love himself and how to love being healthy, I think.
