Physical Needs The most obvious reason you eat is hunger. Hunger is a physical need for food. Your body is demanding food when your stomach growls or you feel weak or light-headed. It needs a fresh supply of energy and nutrients. You eat to satisfy this demand. Social Needs People also eat for social reasons. Eating with others helps satisfy the need to belong and be with friends or family. People may not feel hungry at all when they eat for social reasons. Food and get-togethers seem to go hand in hand. Offering food and drinks to guests is a common way to welcome them. When friends and family gather, they often share a snack or meal. This gives them time to talk and share their thoughts. Think about how often you eat when you are with your friends. You may offer them snacks when they visit your home. You may go with friends to restaurants to eat and talk. You might share a sandwich at lunch. Emotional Needs Did you ever go out for pizza after winning a big game? If you did, you may have eaten because of your emotions. Emotions are feelings. Happiness and love are positive emotions. Negative emotions include being bored, sad, upset, tense, or angry. Both types of emotions can cause people to eat. People may not feel hungry at all when they eat to satisfy emotional needs. Some people eat because of positive emotions. A happy event like a birthday might be celebrated with cake and ice cream.
