The Unfolding Tale of Leptin

The discovery of leptin, a product of the ob gene, in 1994 has raised hopes of many an obese population throughout the world for a probable solution to their fatness. Since its discovery, our understanding of leptin’s biological functions has expanded from anti-obesity to broad effects on reproduction, hematopoiesis, angiogenesis, blood pressure, bone mass, lymphoid organ homeostasis, and T lymphocyte systems. In the brain, leptin transmits the peripheral lipid and glucose metabolic information, activates leptin signaling pathways and elicits a cascade of reactions, leading to reduced feeding, decreased appetite, enhanced mitochondrial oxidation and elevated thermogenesis []. studied the leptin-lowering effect of a 40-week weight loss program in 49 women with obesity comparing two diets: 1) 1000 kcal/day and 2) 1200 kcal/day. Thus, leptin is a critical factor linking reduced energy stores to eating behavior. Leptin is expressed predominantly by adipocytes, which fits with the idea that body weight is .

As you gain fat, the amount of leptin you produce increases; as you lose fat, the amount decreases. Leptin is a protein manufactured by fat cells that is involved in the control of body weight.Leptin resistance occurs in obese patients, but its independent contribution to adiposity and the accompanying metabolic diseases, i.Get a good night’s sleep (sleep deprivation decreases leptin and increases ghrelin [ * ]) Lose weight (leptin levels decrease when you have less fat mass, which increases leptin sensitivity) Stay away from high carb intake, especially fructose, to reduce your risk of developing leptin resistance. If your fasted serum leptin, when tested, is greater than 10 ng/ml AND you have the symptoms of leptin resistance (listed below) then you have the condition of leptin resistance.Leptin is a hormone whose primary job is to signal to the brain and other organs to decrease appetite, increase metabolic rate, inhibit the deposition of fat, and increase physical activity.

Leptin resistance is defined by a reduced sensitivity or a failure in response to leptin, showing a decrease in the ability of leptin to suppress appetite or enhance energy expenditure, which causes a heightened food intake and ultimately leads to overweight and obesity []. So, this is around 20% body fat, maybe 23 to 25% in women.
