During the worst stages of my eating disorder, I was all-or-none with food—either bingeing or not eating. Much of my experience was, in fact, that if I ate anything, I would eat everything. I began to understand that this happened because I was starving myself. In starvation mode, my body literally thought I was facing a famine. It didn’t know that I was living near a grocery store and several fast-food restaurants. Thinking I was facing a real food shortage, its primal instinct was to binge on large amounts of food, conserving fat in preparation for the hard times ahead.
