I really do feel your pain. And the advice I used to get just infuriated me because I used to think 'I have tried EVERYTHING. Every exercise, every diet adaptation' - i even started eating meat again after 23 years a vegetarian. It was so frustrating.
I went to the doctors, I went to the gym, I went to trainers and running clubs - my brother is a fitness instructor, as well as obe of my closest friends, there really was nothing I didn't know about the THEORY, and it felt like I was eating like a bird already.....
But what can I say? Obviously a lot of what I was doing was mindless- start monitoring it and my weight loss happened pretty painlessly. I don't even feel hungry most of the time.
With chatgpt, if you have a nutrition panel on your food, great. If not, you can just take a photo of what you're eating and it will guess, and monitor.
Gives me a weekly roundup. Info on how exercise might be effecting my water retention, inflammation levels, glycogen levels which might effect weight. Looks at other indicators like increased Vo2 levels- i am superior for my age group!!!
Oh, and i highly recommend hyaluronic acid. It draws water away from the surface of the skin into your muscles where it's needed and the difference it has made is huge - I have cheekbones, my tummy went down, I even went down a shoe size!!! I was probably inflamed and retaining water for decades!!!
