A new study suggests obesity can shave years off lives and — before it does — dramatically increase the time obese people spend dealing with two major chronic conditions.
The research, by scientists from Montreal's McGill University, suggests extreme obesity can shorten a life by more than eight years and rob the person of 19 years of healthy life — in other words, time spent without diabetes and-or heart disease.
The work is published in the journal Lancet Diabetes and Endocrinology and was funded by the Canadian Institutes of Health Research.
Lead author Dr. Steven Grover says the biggest impact is seen on people who are obese early in life.
The toll is quite a bit more modest on people who become overweight or obese in their 60s or 70s.
Other studies have estimated what obesity does to life expectancy, but Grover says this study is the first to estimate the loss of healthy life resulting from obesity. - Yahoo News Canada
