A new analysis of almost one million people from around the world has shown that obesity can trim years off life expectancy.
If you are becoming overweight or obese, avoiding further weight gain could well add years to your life.

The Oxford University research found that moderate obesity, which is now common, reduces life expectancy by about 3 years, and that severe obesity, can shorten a person’s life by 10 years.

The analysis brought together data from 57 long-term research studies. People were followed for an average of 10 to 15 years, during which 100,000 died, making it the largest ever investigation of how obesity can cause death.

Among the 900,000 men and women in the study, mortality was lowest in those who had a BMI of 23 to 24. This means that if a person were 1.70m (5 feet 7 inches) tall, for example, his or her optimum weight would be about 70kg.

Epidemiologist Dr Gary Whitlock of Oxford University, who led the analysis, said of the findings: “If you are becoming overweight or obese, avoiding further weight gain could well add years to your life.’’

Obesity increases death rates for some types of cancers, but the main way it kills is by increasing risk of heart disease and stroke.
