Leptin replacement therapy corrects metabolic anomalies (diabetes, dyslipidemia, hepatic steatosis) and reverses obesity in individuals with congenital leptin deficiency or lipodystrophy.

If you have a rare genetic condition causing leptin deficiency or lipodystrophy, leptin therapy is a highly effective, potentially curative treatment for your metabolic issues. However, if you are generally obese, your body likely already has high leptin levels but is resistant to them; taking leptin supplements will not work and is not recommended.

GoodSupportsHIGH confidence
Leptin administration corrects many of the metabolic anomalies seen in lipodystrophic patients including diabetes, dyslipidemia, and hepatic steatosis (25, 26) and completely reverses the obese phenotype of leptin-deficient individuals (27, 28).
