Leptin and Diseases

Leptin is the hormonal signal from fat, the energy store, to our brain. Many functions of our body, like growth and development, energy expenditure, bone health, reproduction etc., are influenced by leptin. Thus leptin is the link that connects our body functions to our food and our energy stores. Excessive production of leptin leads to leptin resistance that in turn can lead to abnormal functioning of all these systems.
