    • Ventromedial Hypothalamus-When stimulated, causes you to feel full.
    • Example of a rat with no ventromedial hypothalamus.
  • Set point theory.
  • Glucose levels.
appetite hormones
Appetite Hormones
  • Insulin: Controls blood glucose, secreted by the pancreas.
  • Leptin: When abundant it causes the brain to increase metabolism and decrease hunger. Protein secreted by fat cells.
  • Orexin: Hormone that is secreted by the hypothalamus that triggers hunger.
  • Ghrelin: Secreted when your stomach is empty sending hunger signals to the brain.
  • PYY: Digestive tract hormone that sends “I’m not hungry” signals to the brain.
psychological factors
Psychological Factors
  • External: Sight, smell, thought of food, and mood.
