Related to these findings in humans, preliminary work in rodents shows that exogenous administration of N-Acylethanolamines, such as oleoylethanolamine (OEA) can normalize high-fat diet induced dopamine decreases in DS and possibly induce a shift in preference (Tellez et al., In Press). Human testing of OEA supplementation is possible based on the availability of a dietary supplement containing the OEA precursor NOPE-EGCG ((PhosphoLEANtm, 100 mg NOPE+50mg EGCG per capsule). PhosphoLEAN has been shown to enhance adherence to dietary advice in overweight healthy subjects (Rondanelli et al. 2009, Mangine et al. 2012).
