Detailed explanation-1: -Ghrelin is a hormone that increases appetite, and also plays a role in body weight. Levels of leptin–the appetite suppressor–are lower when you’re thin and higher when you’re fat.

Detailed explanation-2: -Ghrelin and leptin are two of many hormones that control your appetite and fullness. They’re involved in the vast network of pathways that regulate your body weight. Leptin decreases your appetite, while ghrelin increases it. Ghrelin is made in your stomach and signals your brain when you’re hungry.

Detailed explanation-3: -In contrast to other gut hormones, plasma ghrelin levels increase in response to fasting and decrease on refeeding. Furthermore, plasma ghrelin levels are reduced by chronic intake of high-calorie diets and obesity in humans.

Detailed explanation-4: -For this article, we will focus on the 3 major players: Leptin, Ghrelin, and Neuropeptide Y (NPY). These 3 hormones are the major players when it comes to long and short-term hunger levels.

Detailed explanation-5: -The higher your levels of ghrelin, the hungrier you get. The lower your levels, the more full you feel and the easier it is to eat fewer calories. Therefore, if you want to lose weight, lowering your ghrelin levels can be beneficial.
