A recent study reports that being obese may take up to 8 years off a normal human lifespan.  Defined as a body mass index [BMI] of 35 and higher, the very obese lost about 19 years of healthy life, defined as living free of chronic disease such as diabetes and cardiovascular disease. In a computer modeling study, very obese men lost just over 8 years of life compared with normal-weight men, and very obese women lost as many as 6 years.

Researchers estimated that depending on age and gender, overweight patients (BMI 25-30) would lose 0 to 3 years of life expectancy, obese patients (BMI 30-35) would lose 1 to 6 years, and very obese patients (BMI 35 and up) would lose 1 to 8 years.  The greatest losses were seen among young adults ages 20 to 39, including 18.8 years for very obese men and 19.1 years for very obese women.
