Fatter people may find food more appealing because they have a more intense sense of smell, new research suggests.
Researchers have discovered that the heavier that someone is the more sensitive they are to the smell of food. They believe that this might make the food more appetising to them and so encourage them to eat more. Dr Lorenzo Stafford, of the University of Portsmouth’s Department of Psychology, said that there was a definite correlation but as yet he did not know why.
“It could be speculated that for those with a propensity to gain weight, their higher sense of smell for food-related odours might actually play a more active role in food intake,” he said. “For a certain group of people it could be sustaining food intake by making it more appetising.”
