Obesity is a medical condition characterized by an excessive amount of body fat. It is affects millions of people worldwide, and obese people are at high risk for diabetes and heart disease.
Body mass index is a diagnostic tool that shows if a person is an appropriate weight for their age, sex, and height.
According to the World Health Organization (WHO), global obesity has tripled since 1975.
In 2016, 2 billion adults were overweight, of which 650 million were obese. Incredibly, in the same year, 41 million children under 5 years old were overweight or obese.
In 2013, the American Medical Association (AMA) recognized obesity as a disease.
Their ruling was based on their belief that some people do not have complete control of their weight.
Obesity: Weight And Smell Are Linked
The link between obesity and smell comes from a recent study done by researchers at the University of Otago in New Zealand.
They collected scientific papers showing a link between body weight and sense of smell. They also collected information of nearly 1,500 individuals from clinical worldwide studies.
Their analysis showed a strong link between a person’s body weight and their smell ability. Notably, that the better a person can smell, the more likely that person is to be slim. The converse is also true; the heavier the person is; the worse sense of smell he has.
The researchers conclude that smell plays a critical role when it comes to eating behavior. Indeed, it affects the way we identify and choose between different flavors.
A poor sense of smell does result in people making unhealthful food choices, which in turn, increases their risk of getting fat.
