Intermittent fasting, lifting, calorie counting. The problem is that I am only able to stick to those maybe for a few weeks at a time before I get off track and end up back where I started. Except with weightlifting, I was able to stick with that for a few years, but unfortunately you can't outlift a bad diet. My relationship with food has never been a healthy one, and it's been that way ever since I wad a kid.

I highly recommend trying CBT. In particular the app Noom was excellent at (permanently) reframing my relationship with food.

I've never heard of that app before, I'll take a look at it.
