Getting Healthy With Your Significant Other

It is so much easier when you are doing it together!! My hubs has never needed to lose weight (unlike me) but he is super supportive.
We plan dinners together by how much of a workout can happen (long run, pasta with pesto or homemade pizza; knee hurting, spaghetti squash and marinara...)
When I cook I make sure he gets the extra calories he needs -- not going underweight is a challenge for him in the summer, so that's part of doing it together.
If he's cooking and fixes my plate for me, I can always interview him after and he knows exactly how much I ate of each item, and cooked it low cal.
We plan workouts (long hikes, or runs) into vacations we take. We run together and talk about our workouts and progress.
Just yesterday he said, okay, you inspired me, I'm willing to do a half-marathon just to finish it even if I'm not fast.
It's a great road together, congrats on taking those first steps!

Planning and preparing meals together is awesome, I think.
I hear a lot of people complaining (in real life and on these forums) about their partner being the worst temptation source because they don't really want/care to eat healthy and constantly bring home junk food snacks or suggest dining out near-daily. If your partner's eating healthy too, it's way easier to be on the same page. It's not like you can't go out & indulge sometimes but it's more likely that you will eat/cook at home.

My husband is a great cook and encourages me to eat more vegetables. I like veggies but I know if I was cooking everything myself I wouldn't think to add certain things to our meals like a bunch of roasted cabbage or diced celery, radishes in salad, and so on. I always love what he makes. He has been pescetarian for almost 20 years so that is generally how we eat at home. I'm not pescetarian or vegetarian but I am totally happy with that and mainly eat chicken & beef when I go to restaurants (sometimes not even then). Once in awhile we'll make separate meals and mine may involve meat, but it's relatively rare.

Exercising together is also awesome!
We actually plan our meals out on Sunday and then walk (a couple miles) to the grocery store and get the foods we need for the bulk of our meals. We have cars but it's just kind of our routine & we both enjoy it. Obviously that's not going to work for everyone and a lot of it is related to the layout of our town & neighborhood but I just think it can be really fun to work in a little bit of exercise to normal everyday things you do together. A lot of times we go to different parks and walk, too, and on the weekends we do a lot of hiking or take our bikes to local trails. A lot of our vacations are centered around this too and it's awesome to have a partner who enjoys the same things.

My husband and I are polar opposites when it comes to fitness and weight loss. He does intermittent fasting; I can't live without three scheduled meals, all of which I track. He runs and is into team stuff like softball. I'm into solo workouts (yoga and bicycling) and can't stand running.

But I do all the cooking and have expanded my husband's palate enough that he enjoys more healthy food now, which makes it easier for him to reach his goals, and we constantly cheer each other on and celebrate each other reaching our goals.

We just came back from holiday and my OH decided he wanted to lose weight and wanted to "do that food app thing im on".
Im all up for that. Helps in keeping us both motivated and i love the whole weighing food, going back to basics on cooking and the whole logging food thing.
My OH has commented on how good he feels and sleeps and ots only been 2 weeks!!

My husband isn't actively trying to lose weight and he isn't into exercising but he is very supportive of me and we keep the house clean of junk food like chips, candy and soda and keep the house stocked with fresh fruits and veggies and all my vegetarian substitutes, even the kids have gone vegetarian with me.
