Of the 4 million people who died in 2015 because of overweight conditions, only 60% were considered to be clinically obese.
A study revealed by the University of Washington warns that a significant part of these people had a Body Mass Index (BMI) less than 30, the threshold from which the person is considered obese.
Commitments for the whole year
"People who ignore weight gain put their health at risk," said Christopher Murray, lead author of the study and director of the Institute of Metrics and Assessment for Health at that university.
In other words, for this researcher, people should be careful about extra pounds, even when they are not considered obese.
"Those more or less serious New Year resolutions to lose weight should become commitments for the whole year," advises the scientist quoted by the BBC.
30% of the world population is overweight
The study, which analyzed data for 195 countries, says that 30% of the world's population – or 2.2 billion children and adults – are overweight.
For the researcher, obesity has become a worldwide epidemic – the obese population has doubled in 70 countries since 1980.
Excess weight is related to a higher risk of various diseases, such as obesity, diabetes, cancer, asthma, hypertension and stroke, all of which are life-threatening conditions.
In Portugal, more than half of the population (52.8%) with 18 or more years are overweight or obese. Still, there is no drug for obesity that currently has state reimbursement.
