Key Points

• Hunger Promoter Hormones:
  • Hunger-promoting hormones, also known as orexigenic hormones, are responsible for stimulating appetite and food intake.
  • These hormones play a crucial role in energy balance and metabolism.
• Leptin:
  • Leptin is a hormone produced by fat cells that helps to regulate energy balance by inhibiting hunger.
  • It acts as a satiety signal to the brain, indicating that the body has enough energy stores.
• Insulin:
  • Insulin is a hormone produced by the pancreas that regulates blood glucose levels.
  • It also has an anorexigenic effect, meaning it can suppress appetite, especially after meals when insulin levels are higher.

Additional Information

• Ghrelin:
  • Ghrelin is known as the "hunger hormone" because it stimulates appetite.
  • It is produced mainly in the stomach and signals the brain to increase food intake.
• Orexin:
  • Orexin, also known as hypocretin, is a neurotransmitter that regulates arousal, wakefulness, and appetite.
  • It stimulates food intake and is involved in the reward system of the brain.
