Obesity represents a major risk factor for the development of insulin and leptin resistance, ultimately leading to a pleiotropic spectrum of metabolic alterations. However, resistance to both hormones does not uniformly affect all target cells and intracellular signaling pathways. In contrast, numerous clinical phenotypes arise from selective hormone resistance, leading to inhibition of defined intracellular signaling pathways in some tissues, while in other cell types hormone action is maintained or even overactivated. Here, we review the molecular mechanisms and clinical outcomes resulting from selective insulin and leptin resistance, which should ultimately guide future strategies for the treatment of obesity-associated diseases.
