Pleasure eating triggers body’s reward system and may stimulate overeating
When eating is motivated by pleasure, rather than hunger, endogenous rewarding chemical signals are activated which can lead to overeating, according to a recent study accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM). The phenomenon ultimately affects body mass and may be a factor in the continuing rise of obesity.
“‘Hedonic hunger’ refers to the desire to eat for pleasure, and to enjoy the taste, rather than to restore the body’s energy needs,”says Palmiero Monteleone, MD, of the University of Naples SUN in Italy and lead author of this study. “For example, desiring and eating a piece of cake even after a satiating meal is consumption driven by pleasure and not by energy deprivation. The physiological process underlying hedonic eating is not fully understood, but it is likely that endogenous substances regulating reward mechanisms like the hormone ghrelin and chemical compounds such as 2-arachidonoylglycerol (2-AG) are involved.”
In this study, researchers assessed eight satiated healthy adults, aged 21
