AP PSYCHOLOGY

Detailed explanation-1: -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-2: -Leptin helps inhibit (prevent) hunger and regulate energy balance so that your body doesn’t trigger a hunger response when it doesn’t need energy (calories). Leptin mainly acts on your brainstem and hypothalamus to regulate hunger and energy balance, though you have leptin receptors in other areas of your body.

Detailed explanation-3: -These experiments show that elevations in insulin produce increased hunger, heightened perceived pleasantness of sweet taste, and increased food intake. Finally, a study is described that considers how different insulin levels, produced by the type of food ingested, may affect subsequent food intake.

Detailed explanation-4: -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”.
