Being morbidly obese with a Body Mass Index (BMI) of 40-50 is estimated to reduce lifespan by 8-10 years during the 10-15 years of follow-up when compared to those with a BMI of 22.5 to 25 according to a study by Epidemiologist Dr. Gary Whitlock of Oxford University published on-line in The Lancet on March 18, 2009.
This is equal to someone 5-feet tall weighing roughly 200-250 lbs…
Or someone 6-feet tall weighing roughly 295-370 lbs.
This reduction in life expectancy is roughly equal to the 10-year reduction in life expectancy seen in one study of life-long smokers among male British doctors.
The study analyzed data from 57 long-term studies which included roughly 900,000 people who were followed for 10-15 years.
This is the sixth video highlight from this paper.
