Detailed explanation-1: -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-2: -Leptin is a protein hormone that acts within the hypothalamus to suppress food intake and decrease body adiposity, but it is increasingly clear that the hypothalamus is not the only site of leptin action, nor food intake the only biological effect of leptin.

Detailed explanation-3: -The hypothalamus is the portion of your brain that controls hunger. hormone cortisol, which can create hunger cues. When you eat, your stomach expands. This signal notifies the hypothalamus that it’s time to stop eating.

Detailed explanation-4: -Within the hypothalamus are specific regions where hormones interact to produce sensations of appetite and satiety, leading to food consumption or a feeling of fullness. Through the interactions of ghrelin and leptin, the hypothalamus can regulate the sensation of hunger and satiety, leading to energy homeostasis.

Detailed explanation-5: -The three parts of the hypothalamus that regulate food intake are called the ventromedial nuclei, the lateral hypothalamic area, and the arcuate nucleus. The ventromedial nuclei is the satiety center, and when stimulated, it causes the sensation of fullness.
