According to a new research, being overweight could cut down 8 years from the average lifespan of an individual. It is as dangerous as smoking cigarette. The study stresses on the face that it could reduce life expectancy, and also demonstrated that obese people are more likely to develop diabetes and also cardiovascular diseases, at comparatively lesser age than those who aren’t overweight.

A Body Mass Index of over 35 are likely to lose between one and eight years of life, while those with BMIs of 25 to 30 could lose up to three years.

Lead author of the study, professor of medicine at the McGill University in Canada, Steven Grover said, “In terms of life-expectancy, we feel being overweight is as bad as cigarette smoking.” The study also concludes that excess weight can also cut down a healthy lifestyle by 20 years. Grover also stated that, “Our team has developed a computer model to help doctors and their patients better understand how excess body weight contributes to reduced life expectancy and premature development of heart disease and diabetes.” The team of researchers have analysed the data collected from the National Health and Nutrition Examination Survey from years 2003 to 2010, taking into consideration 4000 cases.

There is also a ratio between weight and age, which needs to be maintained. Explaining which researchers said, “The pattern is clear- the more an individual weighs and the younger their age, the greater the effect on their health.” Researchers found that the individuals who were extremely overweight could loose 8 years of life, and those who were lesser obese, could have around 6 years cut off from the life expectancy, the ones who are mildly overweight, could probably loose out on around 3 years.
