New research has found that some overweight people have a greater sense of smell for food which may cause them to struggle with diets and weight loss.
Carried out by the University of Portsmouth , the study found that those who were overweight, or had a high BMI, had a far heightened sense of smell for food compared with slim people.
Volunteers took part in the study where they were asked to join in with a series of mini experiments that tested their smelling ability.
The results revealed that most people are better at detecting food odours just after they had eaten rather than when they were hungry with experts citing this as one of the reasons many people continue eating long after they are full up.
Scientists believe this new research could help explain why some people struggle to stay slim or stick to a strict diet.
Lead researcher Dr Stafford, said: “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.
“Hopefully this research will stimulate more work in this area with the potential to help those who struggle with their weight and those who treat people with weight problems.”
Those who are worried about being overweight should book a consultation with an expert bariatric surgeon at The Hospital Group.
