There are only ever three reasons for overeating. One: you are in a Cool Hand Luke cream cracker/pie/boiled egg eating contest. Two: you need a shrink. That's when food is a substitute for what you really need: love, free time, friends, clarity. Food fills emotional gaps, which are much more roomy than the average stomach, so it shows elsewhere. Recently, the Priory released research that found half of adults in the UK eat to smother feelings of boredom, loneliness and stress, highlighting the relationship between what we eat and how we feel. We're talking food going from a thing of joy and pleasure to something to be feared.
