I feel for you, and I've been exactly where you are, many, many times.
I think this time the reason it worked was because somehow the planets aligned and I had the right mentality at the right time, with enough space in my life to really work on it. I also scared myself straight by convincing myself I had diabetes, without any real evidence. It's extremely likely that I am/was at the very least insulin resistant though. I might get tested next year when I can pluck up the courage.
My aunt once said to me (years ago, because I've been overweight and occasionally obese my entire adult life) that weight loss would happen when I was in the right frame of mind for it, and that proved true. But it's taken two decades for me to get here.
I am absolutely not pan frying salmon and what not for lunch. There is no way I would be able to sustain this if it took that much effort. I don't eat breakfast, and I have yoghurt and raw rolled oats for lunch. Even making porridge would be a step too far for me (in any case the raw oats have a lower GL). I know you don't like yoghurt, but what about things like cheese and cherry tomatoes? Things you could easily turn into a meal with little to no preparation.
The only meal I have to plan for is dinner, which makes it simple. Also I don't have children so it's just my husband and me, and he is completely on board with it all too, so I know I have it easy in that sense.
There's also no getting away from the fact that this is a low carb diet, and will fundamentally only work if most sugars and refined carbs are cut out. If that's a big change it's going to feel difficult at first.
On the other hand, if it is a big change, it's likely that you will lose a lot of weight quite quickly at first, which is very motivating. I lost 10kg before I hit my first plateau, which made it so much easier to keep going. Also, by the time I'd got to that point my tastes and eating habits had adjusted enough that I didn't want to go back to all the bread and pasta.
Do remember that this isn't keto or low carb bootcamp though - you don't have to cut it all out, and you don't even have to go particularly low carb to start with.
Maybe also you need to work out what works for you psychologically. I too find that the all or nothing approach makes me instantly obsess over the things I am not supposed to have, leading to an inevitable towel throw at some point down the line.
One thing I've managed to do this year is learn how to think like a "normal" person (i.e. one who doesn't have a weight/eating problem, even though I still do, really). At the moment, for example, the in-laws are here for a fortnight. They like to drink every evening and have carbs with every meal. I've done my best to avoid those traps, but we've also been out for dinner a few times and I've absolutely gone to town on chips, bread, rice and so on. It's fine though - after they've gone I will just get back to normal and be extra careful for a few weeks. I am relaxed about it. This is a major mindset change for me. My mantra is, "there is no wagon". The wagon is an excuse, it doesn't exist, so I can't fall off it.
Maybe what I am on is a road. A road with many fantastic restaurants, as well as a farmer's market and a cinema that does bloody good popcorn. As long as I stay walking along my road for about 80% of the time, I'll get to where I need to be, even if I stop off a lot along the way.
