People with normal digestive tracts who abuse their bodies with starvation or overeating. One acquaintance lives on 2 slices of toast for a meal. A dozen eggs are a dozen meals. To the other extreme is another acquaintance who considers a couple of chocolate bars and a soda pop to be a snack. A meal is something deep fried. They always come to mind when I am in tears on the toilet in the early hours of the morning.
