One of the surprising side effects of feeling hungry, says science
New research suggests that hunger hormone could affect your portfolio.
When you are really hungry for a snack, you may want to stay away from these online shopping sales. The hormone that tells your brain that it's time to eat can also convince you that it's time to spend money, suggestsnew search presented at the 2021 meeting of the endocrine society.
Higher levels of the hormoneghèline, the so-called "hunger hormone", which stimulates the appetite, predicted a greater desire for fast monetary rewards, even when delaying the results of the day to receive more money, according to a study by Massachusetts GENERAL HOSPITAL AND HARVARD MEDICAL SCHOOL. The hormone "eating time" can play a broader role in behavior and decision-making related to human reward, such as monetary choices, says,Franziska Plerseow, PhDAssistant Professor of Medicine in Harvard and a co-investigator in the study. It notes that other recent research has connected Ghrelin to impulsive choices and rodent behaviors.
Ghrelin is produced mainly in your stomach, typically when it is empty. The hormone travels to the brain, to the part of the hypothalamus that controlsappetite, triggering the desire to eat. Another hormone, laptin, signals your brain to regulate the appetite. Higher levels of Ghrelin can trigger a greater desire to continue eating. Research suggests that obese people can be particularly sensitive to Ghrelin due to too active receptors and lead to greater food consumption.

The study involved 84 women, aged 10 to 222 years. Thirty-four were healthy control participants, while 50 had a food disorder like nervous anorexia. The researchers tested the blood from the participants for the levels of ghreine before and after the subjects eating an identical meal. After the meal, all participants took a financial choice test. They were asked to choose a preference for a smaller immediate reward, for example, $ 20 right now or a larger delayed amount, $ 80 payable in 14 days.
The control group with higher ghreine scores was more likely to choose the fast, but a quick money amount rather than delaying the gratification for two weeks to earn more money. This choice indicates more impulsiveness, says Plessow.
On the other hand, there was no apparent link between the levels of ghreine and monetary choices in the study participants with a low-weight food disorder. A possible reason? People with anorexia usually have a Ghrelin resistance, Plessow explains and a lower desire to eat. The results of these topics suggest more than the wider ghreine can affect reward processing in the brain.
