[EX Q]: Question: Are anticipatory and consummatory effects of ( hedonic ) chocolate intake associated with increased circulating levels of the orexigenic peptide ghrelin and endocannabinoids in obese adults?
Answer: When motivation to eat is generated by exposure to, and consumption of, chocolate a peripheral activation of specific endogenous rewarding chemical signals, including ghrelin, AEA, and 2-AG, is observed in obese subjects. Although preliminary, these findings predict the effectiveness of ghrelin and endocannabinoid antagonists in the treatment of obesity.
