Merely thinking that what you ate was not healthy and highly calorific can quell your hunger pangs and perhaps help curb overeating, according to a new research and in turn make you stay healthy .
Alia Crum at Yale University and her colleagues gave a 380 calorie milkshake to the participants of the study, saying that the milkshake was either a 620 calorie "indulgent" shake or a healthy 140 calorie "sensible" shake. The team also measured levels of ghrelin – a hormone released by the stomach when we are hungry – before and after participants drank the shake. Those who believed they were consuming a high-calorie drink showed a much steeper decline in ghrelin levels than those who believed they were drinking healthy and something low-calorie, reports New Scientist. The finding suggests that the healthy mindset plays a very important role in how much food you eat at each meal and whether you are still hungry after eating.
