Hunger perception is rated on a scale from 0 to 10. Zero is the mark for extreme hunger and 10 is the mark for extreme fullness. Target numbers are between three and eight. People should begin eating at level three where the urge is strong but not extreme. They should stop at level eight when they are comfortably full. It is important to eat slowly because it takes the brain fifteen to twenty minutes to sense that the stomach is full.
