Also ADHD here, and same thing for me. Hyperfixating on meal planning and strength training has pretty much saved me. It's hard, and I still have to fight food noise daily, but having everything pre-prepped means I have easy, friction free healthy choices instead of reaching for a bag of chips and downing the entire thing while sitting at my desk, or not having the executive function necessary to cook an un-prepped, unplanned dinner and just eating a whole pizza instead.
I also used to binge, and meal planning and pre has also helped with that, as I tend to have periods of either really high food drive, or almost no food drive at all leading to not eating for an entire day, then downing 3000+ calories in one meal.
ADHD sucks. It's often trivialized in pop culture, but it makes life so difficult, and those real difficulties are almost never talked about.
