AP PSYCHOLOGY

Detailed explanation-1: -Ghrelin is a multifaceted gut hormone which activates its receptor, growth hormone secretagogue receptor (GHS-R). Ghrelin’s hallmark functions are its stimulatory effects on food intake, fat deposition and growth hormone release. Ghrelin is famously known as the “hunger hormone”.

Detailed explanation-2: -Your stomach releases ghrelin when it’s empty to signal your brain that it’s time to eat. Ghrelin is often called the hunger hormone, but it does more than control hunger. It also signals your pituitary gland to release growth hormones, plays a role in insulin release and protects your cardiovascular health.

Detailed explanation-3: -Of the two hormones, leptin–the appetite suppressor–appears to be the bigger player in our bodies’ energy balance. Some researchers think that leptin helps regulate ghrelin. Leptin helps signal the brain that the body has enough energy stores such as body fat.

Detailed explanation-4: -Ghrelin is a hormone that is produced and released mainly by the stomach with small amounts also released by the small intestine, pancreas and brain. Ghrelin has numerous functions. It is termed the ‘hunger hormone’ because it stimulates appetite, increases food intake and promotes fat storage.

Detailed explanation-5: -Leptin is a mediator of long-term regulation of energy balance, suppressing food intake and thereby inducing weight loss. Ghrelin on the other hand is a fast-acting hormone, seemingly playing a role in meal initiation.
