Hunger is one of the most basic human drives. Propelled by intense hunger, people in a starvation situation will eat nearly anything. In our current state of societal abundance, most of us never experience true hunger. As a result, we're often out of sync with our bodies' natural regulation of hunger, appetite, and satiety. The people most out of sync are those who struggle with their weight. People with weight control issues typically have problems managing appetite and hunger, and responding to satiety signals. They are extra-sensitive to appetite and hunger cues, and almost oblivious to feelings of fullness. They may be easily stimulated by external influences such as the sight of food, and have frequent cravings.
