They’re of the opinion that the better a person can smell, they more likely they are to be thin.
have revealed a link between obesity and scent, finding that the better a person can smell, the more likely they are to be slim.
“After compiling our evidence we found there is in fact a strong link between a person’s body weight and their smell ability,” the Herald quoted lead-author of the study, doctor Mei Peng from the University of Otago’s Department of Food Science, as saying.
“We found obese people’s ability to detect and discriminate smell was not as efficient as slim people. This can result in obese people having a higher chance of making poor food choices because they will need other forms of stimulation to enjoy food.
“For example they might choose, or be more attracted to, saltier and tastier foods such as bacon and maple syrup instead of blander foods such as low-fat cereal with less sugar.
“Cutting the stomach could change nerves in the stomach that affect the gut-brain pathway, so smell changes could be the key to the difference between the two surgeries – essentially the smaller size of the stomach might not be the factor that leads to weight loss, it is more likely due to the gut-brain pathway being reset.”
The study, which happened earlier this year, reviewed data of over 1,400 individuals from worldwide studies – and was supported by a Royal Society of New Zealand Marsden Fast-Start grant.
