When I was a child, I lay in bed at night and fantasized about using a razor-sharp knife to carve fat off my body. First, it would be my stomach, and then my arms. My double chin bothered me too. I had started the habit of keeping my chin lifted up, so the beagle-like droop of my double chin wasn’t so obvious. It didn’t occur to me how horrible it was to think about slicing flesh off my own body. I just knew I hated being fat.
