The solution for me was the approach taken by Gillian Riley, in her book

It isn't about what food you eat, one strand that really resonated for me was finding a sense of choice around eating. I'm very rebellious by nature, and any suggestion that I should restrict my food intake sets me up to prove that I can eat and eat and eat.
The best part about it was finding a sense of peace around food. That I can eat it or not eat it, have it in the house or not. And still feel in control of my eating. Priceless.
Hope you find what works for you.
