OP, I mean this kindly, because I was you for most of my adult life, and part of my teens (other than the year I lived miserably off low cal cup-a-soup and hot chocolate in a desperate attempt to be skinny): you are making a lot of excuses.
You say you have to eat lots of carbs because you always have. You can't exercise because this or that thing. You can justify Soleros because it's hot (when a glass of iced water is all you actually needed). I used to think exactly like this, and I was kidding myself. For decades.
Some lucky people can eat a lot of carbs, or lose weight easily on simple calorie restriction, others can't. You may not be one of them.
That aside, you're talking about not wanting to restrict or deprive yourself by reducing carbs, but you are depriving yourself. You are restricting.
You're depriving yourself of the fat and protein your body needs in order to function, in favour of the carbs and sugars that it doesn't need. Carbs and sugar are delicious, but there is no metabolic need to eat them, unlike fat and protein. You're depriving yourself of crispy chicken skin, full fat yoghurt, proper cheese, olive oil - all things that are delicious and good for you. How is that not restrictive?
It's brilliant that you have increased your vegetables - that's all fibre, and it's crucial for gut health - but you are not eating nearly enough protein or fat. Fat and protein are not when-I'm-thin luxuries, they're a necessity for health. Carbs are the luxury. You need to switch them round in your head.
If you lower your calorie intake even further, the chances are you'll fall off the wagon anyway, because you'll be hungrier. Especially if you keep eating all those carbs and fruit, and drinking all those sweet drinks, because sugar makes you hungry.
You don't need to go to the gym, you can do a few simple resistance exercises at home every day, and build them up as you get fitter and stronger. You can do a couple of ten minute HIIT workouts from an app each week. That's how I started, because I hate exercise, but I know I'm kidding myself if I think I don't need to do it. It's still a chore, I'll never be one of those people who leaps out of bed at 5am and goes for a run, but at 40 I'm now fitter, stronger and thinner than I've ever been in my life.
Sorry, hope that doesn't come across as haranguing. I empathise because, like I said, I used to say all the same things you are, and my diets never worked then either.
