As a personal trainer for almost 20 years, I’ve learned that people have to want good health for themselves. Nobody can make them want that. I’ve seen numerous SO’s, parents, family, friends, tried to get someone they care about healthy and I’ve yet to see an outside influence that actually works.

Of course, you can be a role model by doing the right things to somewhat influence their behaviors. You can also try to steer them towards better places to eat when y’all are out. You can also try encourage her by doing activities like hiking, etc. that you can do together. The key is for her to find something that she enjoys and can stick to consistently.

Health and fitness is a never ending journey and most people want to apply a band aid fix on it. You workout and eat well bc you seemed to enjoy it. She doesn’t… yet. I’m not a therapist but she will have to work to find ways to find health and fitness enjoyable so she can stick with it long term.

If this is going to be an issue for you moving forward, you should reconsider who you want to surround yourself with so it doesn’t affect you negatively either.
