New Delhi: The state of mind may influence how satisfied a person feels after a meal and how likely he is to still feel hungry, claims a new study.The study by Yale University, which appears online in the journal `Health Psychology`, could have implications in the fight against obesity, say researchers.The research team focused on levels of ghrelin, the `hunger hormone` in the gut, which stimulates the appetite andfeelings of hunger. Ghrelin levels typically increase before meals and decrease after meals. The higher the levels of ghrelin in the system, the more likely a person is to overeat.
The ghrelin response to perceived calorie counts wasconsistent with what would be observed had the counts actuallybeen that high or low. "This study shows that mindset can affect feelings ofphysical satiety," said lead author Alia J Crum of thedepartment of psychology at Yale. "The brain was tricked intoeither feeling full or feeling unsatisfied." As elevated ghrelin levels can cause increased bodyweight and fat gain through increased caloric consumption,this study may open new avenues in the fight against obesityby providing insight into how the mind and body work togetherto impact responses to food, the researchers said.PTI
