Leptin Resistance - Or Why Leptin Fails to Work in Obesity

Abstract
In experimental models of obesity high serum concentrations of leptin without subsequent inhibition of food intake indicate a resistance to the physiological effects of leptin. Similar to the animal model leptin concentrations in most of the obese patients are higher compared to normal-weight persons. The postulated leptin resistance is one major target in the search for a better understanding of obesity and the development of pharmacological tools to treat this spreading disease.
