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.
