Welcome!
I do Intuitive Eating and while it's not for everyone, at the beginning I spent a while working out which foods made me really hungry (for me: sugary stuff) and which don't (protein & veggies). I totally recommend doing this whatever plan you choose, it's helped me make the future changes stick better, and recover more easily from setbacks
Best of luck and congrats on making the decision to join! Great support all over this forum
