I've been doing IF for the past five years or so (after "discovering" it by myself) and lost about 30 kg in the process. I am a bulk eater and I still "binge" periodically. The kinds of food that I binge on have changed greatly though, and that's what worked for me. I switched to simpler food: non-starchy grains like buckwheat, kidney beans, vegetables and fruit, and this stuff: https://en.wikipedia.org/wiki/Quark_(dairy_product) . I dropped almost every kind of processed food (I am not an American though, and we never had the same level of dependence on processed foods anyway). I can't even eat sugar and candies anymore, they overflow my senses and taste like crap.
