New research has found out that the brains of overweight people responds less to the hunger feelings when responding to the smell and taste of food, as compared to the healthy weighted individuals.

The study was presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the society for research in eating and drinking behaviors, and admitted that that hunger feelings have less effect on the brain response towards the smell and taste of food in overweight individuals.

The researchers tested the brains of healthy and overweight volunteers and found that the overweight participants had lesser activity in response to the smell and taste of food.

The research was based on the fact that healthy weighted individuals responded to the food smell in their hunger state more as compared to the over weighted individuals.

The researches then concluded that feeling of fullness brings a good brake on the eating, whereas, for some individuals this is not the case so, thus resulting in gaining weight of such individuals.
