leptin

Leptin is a hormone produced by your body’s fat cells, often referred to as the satiety hormone or the starvation hormone because of its role in appetite regulation and energy expenditure . It essentially tells your brain when you’re full and should stop eating.

Leptin levels are directly proportional to the amount of fat tissue you have. The more fat cells you have, the more leptin your body produces. This leptin then travels through your bloodstream to the hypothalamus, a part of your brain that controls appetite. When leptin reaches the hypothalamus, it binds to receptors, sending a signal that you’re full and should stop eating.

Here’s a summary of leptin’s key functions:

• Appetite regulation: Leptin signals to the hypothalamus to suppress appetite and increase satiety (feeling full).
• Energy expenditure: Leptin increases energy expenditure, helping your body burn more calories.
• Fat storage: Leptin plays a role in regulating fat storage.
• Reproduction: Leptin is involved in regulating reproductive function in both men and women.
• Immune function: Leptin may play a role in regulating the immune system.
