Verified step by step guidance

Understand the role of leptin: Leptin is a hormone primarily produced by adipocytes (fat cells). Its main function is to regulate energy balance by inhibiting hunger, which in turn helps to maintain body weight.

Recognize the mechanism of leptin: Leptin acts on receptors in the hypothalamus of the brain to suppress appetite and reduce food intake. It signals the brain that the body has sufficient energy stores, particularly fat.

Eliminate incorrect options: Increased blood glucose levels, release of insulin from the pancreas, and production of thyroid hormones are not directly stimulated by leptin. These processes are regulated by other hormones and mechanisms.

Focus on the correct physiological effect: Leptin's primary action is the suppression of appetite, making this the correct answer based on its role in energy homeostasis.

Relate leptin to broader physiological concepts: Leptin is part of a feedback loop that helps regulate energy intake and expenditure. It works in conjunction with other hormones like ghrelin (which stimulates appetite) to maintain balance in the body.
