Because of obesity in young people, they would lose up to 10 years of life expectancy, according to the study

A significant overweight can be the
life expectancy, according to a study published this Thursday in the journal International Journal of Obesity. Heavy obesity at 20 or 30 years can shorten the life span of ten years.

Specialists have developed a model that allows them to determine the number of years of life that people have, whether they are overweight, obese or have morbid obesity.

It is worse for men

The calculation method developed by the researchers shows that in the twenty years up to six years, obese women can lose life expectancy and men up to eight years. An extra shortening of two years is observed when obesity is particularly important.

On the other hand, participants in a study with a healthy weight between 20 and 29 years can enjoy 57 years of life for men and 60 years for women.

Loss of millions of years of life

In total, the current Australian population is about to lose 36.3 million years of life, according to the survey. Men would lose 27% more years than women. The situation would be similar in other developed countries, say the researchers.

"Our model predicts an increase in adult obesity by 35% by 2025," warns Thomas Lung, co-author of the study. "We now need to act to have a strategy for obesity prevention that targets adults of all ages, but especially young people."
