Many fortunate individuals never want to eat more or less than they need to maintain their ideal weight. When they exercise a great deal they eat more heartily than when they spend a quiet day at home; and if they have a huge Thanksgiving dinner at noon, they just aren’t hungry for the next meal. Their appetites are regulated by their requirements, and they seldom develop bad eating habits. People who don’t go above or below their normal weights usually have appestats that are set exactly right. In many people, however, the appestat is easily influenced or conditioned by habit. On the other hand, people who don’t get enough to eat for some time may develop poor appetities. Children coming from families that love food and make a happy event out of each meal, often grow up to be adults whose appestats are set too high, while those from homes where meal times are unpleasant, the food skimpy and poorly prepared, may have low appestats. Emotional factors can play an important part in overeating or undereating. People who feel lonely and unwanted often eat a great deal because it is one of their few pleasures. Women with small children have frequently told me they eat simply in order to have something to do, being bored by having to stay how so much, or because it makes them feel calmer and better able to cope with the children. On the other hand, worry and tension can also keep people from eating, together with such psychological squirks as the desire from attention and sympathy. Deep psychological problems naturally call for the help of a specialist.
