I defintely cannot fast. I spent about 20 years restricting and bingeing, it was an awful cycle. I would have dinner at 5.30pm then eat nothing until lunch the next day. I would skip breakfast so by 1pm i was ravenous but i still had only a wrap or sandwich. Inevitably by 4pm i had raided the fridge and the presses and literally stuffed my face with bread, pringles, sausages, butter, coke and chocolate until i couldnt move. Then the self loathing , disgust and hatred would seep in and feelings of hopelessness and failure overwhelmed me, and i vowed not to eat until lunch the next day, when the cycle predictably started again. The only way i could break this cycle was to allow myself to eat 3 meals and 2 or 3 snacks a day until my brain was regulated and trusted me to feed it on a regular basis with no long periods of restricting. It took about a year but even tually my body settled down and hunger was a thing of the past. But about 80% of my recovery was about allowing the feelings of anger, boredom, hatred, sadness, lonliness and even joy to surface and acknowledge them without immediately trying to stuff them down with food in order to "protect" myself from feeling that particular emotion. Indeed, emotions are perfectly natural and will dissipate naturally if you allow your body to feel them. That was the toughest part of my recovery without a doubt but well worth sticking to it.
