Which of the following is termed a hunger hormone as it stimulates appetite, increases food intake and promotes fat storage?

Option 4 : Ghrelin

The correct answer is Ghrelin.

• Small amounts of ghrelin are also released by the small intestine, pancreas, and brain.
• Ghrelin is primarily synthesised and released by the stomach.
• Ghrelin serves a variety of purposes. Because it stimulates appetite, increases food intake, and encourages fat storage, it is known as the "hunger hormone."
• Ghrelin circulates in the bloodstream and works in the hypothalamus, a region of the brain important in the regulation of appetite, increasing food intake in humans by up to 30%.​

• The INS gene in humans encodes insulin, a peptide hormone generated by beta cells of the pancreatic islets.
  • It is regarded as the body's primary anabolic hormone.
• Resistin is a cysteine-rich peptide hormone produced by adipose tissue and is encoded by the RETN gene in humans.
  • Other names for resistin include adipose tissue-specific secretory factor (ADSF) and C/EBP-epsilon-regulated myeloid-specific secreted cysteine-rich protein (XCP1).
• Leptin is a hormone primarily produced by enterocytes and adipocytes in the small intestine.
  • It inhibits appetite, which in turn reduces fat storage in adipocytes and aids in the regulation of energy balance.
