AP PSYCHOLOGY

Detailed explanation-1: -What is leptin? Leptin is a hormone your adipose tissue (body fat) releases that helps your body maintain your normal weight on a long-term basis. It does this by regulating hunger by providing the sensation of satiety (feeling full).

Detailed explanation-2: -Leptin decreases your appetite, while ghrelin increases it. Ghrelin is made in your stomach and signals your brain when you’re hungry. Your fat cells produce leptin. Leptin lets your brain know when you have enough energy stored and feel “full.”

Detailed explanation-3: -Leptin is a hormone released from fat cells in adipose tissue. Leptin signals to the brain, in particular to an area called the hypothalamus. Leptin does not affect food intake from meal to meal but, instead, acts to alter food intake and control energy expenditure over the long term.

Detailed explanation-4: -The circulating leptin level serves as a gauge for energy reserves and directs the central nervous system to adjust food intake and energy expenditure accordingly. Leptin exerts immediate effects by acting on the brain to regulate appetite (Figure 1).

Detailed explanation-5: -Leptin sends a signal to your brain that helps you feel full and less interested in food. You may hear it called a satiety hormone. (Satiety means hunger feels satisfied). It also plays a role in how your body turns fat into energy.
