  4. Motivation • Homeostasis • tendency to maintain a balanced or constant internal state • regulation of any aspect of body chemistry around a particular level • Incentive • a positive or negative environmental stimulus that motivates behavior

  7. Motivation-Hunger • Glucose • the form of sugar that circulates in the blood • provides the major source of energy for body tissues • when its level is low, we feel hunger

  8. Insulin • Hormone which allows the body to use glucose for energy or fat production • As insulin levels increase, glucose levels decrease.

  9. Leptin • Protein produced by bloated fat cells • Send a message to “stop eating”

  10. Orexin • Hunger-triggering hormone • Produced by the hypothalamus • As glucose levels drop, orexin levels increase and person feels hungry

  11. Motivation-Hunger • Set Point • the point at which an individual’s “weight thermostat” is supposedly set • when the body falls below this weight, an increase in hunger and a lowered metabolic rate may act to restore the lost weight • Basal Metabolic Rate • body’s base rate of energy expenditure
