I'm not doubting that there is a correlation between the glucocorticoid receptor gene and over eating, but I think that most of the reason lies on the psychological and social realm of a biopsychosocial explanation. I think that everyone is susceptible to binge eating as well as anorexia because i'm pretty sure that everyone is capable of being anxious.If there was such a strong correlation between this gene and binge eating, then I think a much smaller portion of the population would be suffering from eating disorders, and not just those with the SNP.
