To be concerned about husband's weight

[Littlelighthouse]

DH has always been on the 'bigger side' as long as I've known him. His weight isn't something that's ever bothered me attraction wise, but since having a child it's something I've grown increasingly concerned about.
He's 6ft 2, and the number on the scales has always been 'bigger', but he always looked in proportion to his height. However, since covid, things have just gotten really out of hand. He's an emotional eater and if he's sad he turns to food, just as if he's happy/wants to celebrate he turns to food. He hasn't weighed himself for months now, but last time he did he was over 19st and was disgusted with himself, which was so hard to see. I know he can lose the weight though, as for our wedding he decided to and he lost 2 stone (bringing him to just over 15st at the time) and honestly looked in the best shape I'd seen him in and he said he felt better/healthier too, but then it was covid.
We come from very different backgrounds regarding eating/exercise. As a child I hardly ate out/had takeaways (more of a parents financial issue than anything else), and exercised 3 times a week through various activities from being about 6 years old. DH, however, had parents who worked long hours and so they relied on McDonald's/burger king etc. He also did no out of school activities/exercise. His parents and siblings are all also overweight.
We are very open, and I've shared my concerns about passing bad habits onto our child, but he is very adamant that he doesn't want them having the same upbringing around food that he did.
But my biggest concern is that his dad is currently in hospital with heart failure (+other things caused by his weight). He's only in his late fifties, and I can sadly see this being th future for my husband and it terrifies me.
I've tried to talk to him in the past gently, and he says he wants to change, but he does absolutely nothing to make those changes. It's such a sensitive subject for him and it's something he was bullied about growing up, so I'm cautious to not evoke shame, but I also feel like I'm just sitting back and watching him put himself in an early grave.
So AIBU to be concerned? And if not, how would you gently approach the subject again?
Thank you

But if OP's dh gets in to it, he will eat better, and many men like the "evidence" it gives. Of course you are right, but ATM this man isn't eating well. If course he could just choose to eat better. But sometimes it's not that easy.

The recipes and foods recommended by Zoe are very healthy. It's not rocket science in any way. It boils down to, eat more veg, pulses and nuts, a bit of lean meat, drink in moderation. Cook from scratch. Avoid highly processed foods and white carbs. Of course I knew all that before. But paying 200 quid or however much it was and seeing the impact of foods on me - seeing my waking blood sugar hovering at around 6.5 - has made all the difference to me. So carry on feeling superior that you didn't need the extra push to apply those healthy eating principles. I did, and I am happy to have spent it.

Lol at me being sponsored content! Mumsnet can vouch for me having been here years and years.

It's just something I personally found helpful, and I have noticed a lot of men being interested in - in fact the guy who does my tesco click and collect was asking me about it last week - and it's in the zeitgeist at the moment so I thought he might find it interesting. It was just a suggestion, like all the others here.

I haven't misunderstood anything @TallandSkinny.

Adults don't need to be patronised and told how to eat - they know. It's just the reasons behind food addiction and other issues are often incredibly complex and just being told to use an app or eat more fish is completely pointless.

@TallandSkinny "microbiome" became a buzz word recently and Zoe, alongside other dubious businesses, fully capitalize on the buzz. But even superficial research into the topic will tell you people have vastly different microbiota in their gut and what is normal for me isn't normal for you. Therefore the "personalised poo samples" are as useful as.. well ... poo. Since nobody can actually tell you what you are supposed to do with this information.
As far as sugar and fat spikes, what is Zoe telling you that you don't know about dietary guidelines already? Eat complex carbohydrates, fiber and protein, avoid excessive amounts of saturated fats. Really, I don't need to have a make-shift lab in my house to follow what is already an established guideline.

Look, maybe I am a sap or an idiot. Maybe I enjoy being treated like an idiot or patronized (not that that was my experience, but you guys obviously know better).

And as a person with family members with autoimmune conditions, imo the microbiome is more than just a buzzword. Yes research is in it's infancy. And apparently the data from Zoe participants has revealed quite a high number of previously unknown gut microbes. Who knows what their importance might be; there isn't the research yet. Zoe is contributing to that body of knowledge which I find mildly exciting.

I just found it helpful, ok? And have found many more men interested and asking me about it that when I did slimming world or whatever. It was just a suggestion.

I don't actually think there's anything wrong with using apps if it helps you, but I do think you need to careful how you suggest them to other people - especially if they haven't actually asked for your advice in the first place.

I just feel that if a woman posted on here about how her husband was changing her diet by cooking her fish and vegetables, or was trying to suggest "fun activities" or apps to help her lose weight, he'd be hung, drawn and quartered for being controlling.
