Leptin is a hormone produced by fat cells that signals the brain to regulate appetite and energy expenditure. In healthy individuals, higher body fat produces more leptin, reducing hunger. However, many overweight individuals develop 'leptin resistance,' where the brain no longer responds to high leptin levels. Understanding your leptin level can provide insights into metabolic health and weight management challenges.
