    Am J Physiol Regul Integr Comp Physiol 295:R1370-5. 2008
    ..Our data indicate that chronic fructose consumption induces leptin resistance prior to body weight, adiposity, serum leptin, insulin, or glucose increases, and this fructose-induced leptin resistance accelerates high-fat induced obesity...
