Mood-induced eating. Interactive effects of restraint and tendency to overeat.

Authors: Yeomans, M.R., Coughlan, E.
"These data suggest that restraint alone is a poor predictor of likelihood of overeating in response to stress, which may explain discrepancies in the existing stress-eating literature, and also suggest that positive mood enhances the tendency to overeat in the absence of restraint." Take this one with a big hunk of salt -- what constitutes overeating and why it may happen (or its value to your energy requirements) is not assessed in this review [site owner comment].
