To have suggested this would help your career

[RainRunner]

DH is in a bit of a lull with his job currently. He hasn’t been eating overly healthily or exercising as much as he used to either.

Do you think it’s wrong to say that getting your nutrition in order and a solid fitness regime can help your career? More energy, clarity of thinking etc. He disagrees with me.

Plenty of evidence that people who aren't physically fit can be very successful.

Sounds like you really want to talk to your partner about lifestyle choices and are using his recent job issues as a opening. Not surprised he has seen through this and the conversation was consequently derailed
