unsupportive household

I do , but I got to point I don't care, I don't need him or his support I need my sanity. I plan live a lot longer and healthier them him and I kids think about. It's his Lost not mine , Lost 23 pds so far, do it for your self girly Denis

It's not a problem I have, so I'm not really qualified to comment, however.. there is a big difference between not being interested in joining in and being deliberately awkward and sabotaging your efforts. You just do your thing, for you, and if he jumps on board later then great!

When I started my first fitness journey, I was talking about it at home for a couple weeks, what methods sounded realistic and proven (MFP/NHS weight loss plan) and which sounded less scientifically sound, whether I actually WOULD lose any weight (I honestly didn't think I would. Ha!) and what it might entail. All of this meant that by the time I started logging everything, my partner knew this was going to be happening. We split the meal prep between us, and I showed him the changes I was making (cooking with less oil or water, what an actual portion of rice looks like, etc). He was under no obligation to follow along, but knew that if he didn't, we wouldn't eat the same thing. For him, there was vastly more value in sharing meals and experiences than in not changing.

As so many have said, you can only choose for you. And as you go through this process toward a healthier, fitter you, you will adapt and learn. You can't help it - it's the outcome of experience. Be open to allowing your husband to adapt and learn as well. @warrenlightyear 's story is an excellent example of an OH learning from experience.

You're not doing this alone. There are, what, two dozen of us on this forum alone who have your back. Being the only person in your home doing this just means you are a trailblazer there. And please, please make sure that if your husband is doing things that make your work harder - offering bites, insisting on going out for pizza, hiding your keys when you're trying to get to the gym, whatever it may be - talk to him about it. Give him the chance to not actively obstruct. But don't expect him to know what affects it has on you unless you talk to him about it. And even if he doesn't change, don't let that derail you. You can do this.

I agree with what everyone has said, there is a huge difference between him actively participating and just being supportive.
My husband is overweight too, not by a lot, maybe 40 or so pounds, and so we've talked a lot about losing weight, and I've been a chronic starter in weight loss since we've been together. He hasn't actively participated with me, but he doesn't complain if I make a healthy meal for dinner, though for example, if I make spaghetti, I'll eat mine with spaghetti squash, and make him pasta if he wants. I do the majority of the cooking in our family and we live with my mom still so that's a challenge in and of itself. He hasn't complained about my slight changes in cooking, like using ground turkey instead of ground beef in some things, or eating less red meat.
My mom is always another story, she was born in the 50's so it's all cream based, carb heavy foods. She's also got a very unrealistic view of how weight loss is supposed to work and nags at me if I have something that's not 'diet food'.

I'm the only one 'dieting' in my house so its only my attitude which decides if I will lose weight/get fit -I exercise alone (walking initially but gonna try a running program - eek) and food planning involves cooking what I want with additional for them! I found it much easier to ignore their choices as time went on (7weeks in now).
You have to be a bit selfish, focus on you and you never know, he may follow!

P.S I spend a lot of time prowling these pages so you are never truly alone
