My mother told me this several years ago. I was on a
diet and had plateaued. I was very depressed. She told me to go out and get some pizza. I did, of course, who can argue with that? Then she told me to go back to my
diet for the rest of the week- wouldn't you know it? I dropped the ten
pounds I should've lost during the plateau. I have no idea what the scientific reason is- perhaps your
body is worried about starving?
