OBESE people could have put on more weight because they are better at sniffing out food, scientists have claimed. Boffins say tests showed those with a higher Body Mass Index also have a heightened sense of smell when it comes to identifying food odours. The team from the University of Portsmouth claim this ability to sniff out food could be directly linked to their weight gain. Tests were conducted on 64 volunteers to assess their ability to smell food and non-food items before and after eating. It was also found that people are generally better at smelling food after eating... and that the test should not have been conducted above a Greggs. -Newslite Dr Lorenzo Stafford said: What these findings suggest are that individuals with higher BMI have impaired sense of smell to odours unrelated to food. But when it comes to food odours, the same individuals perform better. 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. -Newslite
