I agree with @DeQuin
Focussing on eating for health has SO helped me... I feel full and satisfied and find I don't often want to binge. I eat masses and have lost lots of weight doing this, alongside IF. Piles of veggies, berries and protein with a good amount of calcium and gut-friendly food is now what my body craves... and I never thought I would say that!!
So yes, I do think there is a significant physiological element. That having a healthy gut and a full stomach takes away some of the levers for craving. As well as the delight in "eating for pleasure and for health" which is what I now aim for... realising how little pleasure there is in binging, and how much there is in having a beautiful pud at the end of a meal.
I genuinely now love thinking about what I'll enjoy eating and finding things that are healthy and delicious, as well as happily eating chocolate and cakes just not so often.
That said, I do know that after a lifetime of binge eating, I am still vulnerable... if I'm very stressed or overwhelmed, it can pop up ... but it doesn't always. I haven't done those 8 days of binging, entering a carb-coma, I did in the past for over 7 years now. And it is increasingly rare for me to even binge for just a day - I can go for months without . But in tough times, yes, I eat... several periods of grief and I notice I put on 2 stone each time but the difference now is, that I often overeat healthy food - huge bowls of berries, yogourt and muesli, and find them deeply satisfying... and noticing what helps calm and soothe me. Yes, sometimes its a whole box of chocolates and a tub of icecream but far far less often now.
So not yet got the whole answer... but well on the way, enjoying the journey and just observing what my body/mind say and want at different times.
