(STUDY FINDS) – Among other functions, the stomach hormone ghrelin triggers appetite and initiates the accumulation of fat in the body. Now, research indicates the “hunger” hormone may also trigger impulsive spending, especially when it comes to items that “feed” the brain’s reward center.
According to co-author Franziska Plessow, Ph.D., assistant professor of medicine at Massachusetts General Hospital and Harvard Medical School, this study reveals unique indications that ghrelin influences financial choices in humans. Similarly, ghrelin may have a role in spontaneous activity and decisions, according to her analysis of current studies in rats.
“Our results indicate that ghrelin might play a broader role than previously acknowledged in human reward-related behavior and decision making, such as monetary choices,” Plessow says in a media release. “This will hopefully inspire future research into its role in food-independent human perception and behavior.”
