PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -[3] Together, ghrelin and leptin signals regulate our sensations of hunger and satiety by sending signals to different nuclei within the hypothalamus for food intake. An imbalance or dysregulation of these hormones may drastically affect the body’s 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: -Leptin and insulin share common effects in the control of food intake and energy metabolism. In the blood glucose homeostasis, both play important roles. Leptin and insulin directly regulate each other : 0 leptin inhibits insulin; insulin stimulates leptin synthesis and secretion.

Detailed explanation-4: -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-5: -Ghrelin, the hunger hormone, is known to influence insulin secretion. Insulin secretion is also known to influence the hormone Ghrelin.
