Moderate obesity takes years off life expectancy

From the University of Oxford in the UK, a new analysis of almost one million people from around the world has shown that obesity can trim years off life expectancy. The Oxford University research found that moderate obesity, which is now common, reduces life expectancy by about 3 years, and that severe obesity, which is still uncommon, can shorten a person's life by 10 years. This 10 year loss is equal to the effects of lifelong smoking.
