i have some tips as someone who eats for the dopamine hit a lot but you kinda need to like, stick to these things... i stopped sticking to it cos mental health problems and the 50 or so lbs i lost came right back

• just gotta stop snacking. especially before bed for me. don't have easy access to snack food. the only food you should keep that is instant access is like... protein shakes and fruit and veggies and stuff
• eat something yummy and filling at meals. don't do whatever diet nonsense, because the most important thing is the first thing on the list, it's better to get that dopamine hit at meal times than never or else it's hard to stick to. i usually go for rice dishes because they're delciious and filling and easy to make.
• i found counting calories good for my autism brain for sticking to things
• exercise wise i just went for a walk every morning and would do more proper exercise when i had the executive function to do so

also i personally dont really get hunger signals until im starving and about to pass out, so i always try to eat at a scheduled time
