Obesity cuts life expectancy by up to 8 years, study finds

Obesity can cut life expectancy by up to eight years - and cost people up to 19 years of healthy living, according to new research.

A new study in the Lancet Journal has found that those with 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.
