Obesity and mortality: Avoiding a weight gain of 20-30 lbs increases life expectancy by 2 years

An overweight adult who avoids gaining 20-30 lbs increases their life expectancy by about 2 years according to a study by Epidemiologist Dr. Gary Whitlock of Oxford University published on-line in The Lancet on March 18, 2009.
“In adult life, it may be easier to avoid substantial weight gain than to lose that weight once it has been gained,” the last paragraph of the paper notes.
“By avoiding a further increase from 28 kg/m² to 32 kg/m², a typical person in early middle age would gain about 2 years of life expectancy.”
This is 4 units of Body Mass Index (BMI).
Four (4) units of BMI is equal to 20 lbs for someone who is 5-feet tall, or…
30 lbs for someone who is 6-feet tall.
This according to a study by Epidemiologist Dr. Gary Whitlock of Oxford University published on-line in The Lancet on March 18, 2009.
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 seventh video highlight from this paper.
I will post other highlights.
