Most people experience a change in appetite when they are stressed. While about 10% suffer a loss in appetite, 90% tend to overeat. Undereaters are victims of acute stress, in which the body prioritizes actions other than eating and therefore suppresses hunger.
For most people, however, stress is a chronic condition, wherein the body is constantly responding to low-grade stress, which might go unnoticed. Since the system is constantly stressed, it begins to conserve energy and build larger reserves to deal with the overload. Thus, people develop a large appetite and begin craving energy-boosting, high-carbohydrate foods.
