Does Pleasingly Plump Mean Better Health?

In the confusing jumble of studies on weight and health there’s been a particularly perplexing wrinkle. Why is it that being overweight doesn’t raise your overall risk of dying from disease but being obese or underweight does?
A published in JAMA this week sheds some lighten on the seeming paradox. Federal researchers combing health statistics collected from 2.3 million adults from 1971-2004 found that being overweight — having a (BMI) between 25 and 29.9 — increases risk of death from certain health conditions such as diabetes and kidney disease but not others such as cancer and heart disease. In some cases say. Alzheimer’s and Parkinson’s being slightly overweight may even defend you from death.
On the other hand being obese having a BMI of over 30 or being underweight a BMI less than 18.5 is associated with a higher mortality evaluate.
bring about study author. Katherine Flegal a scientist at the CDC told the that “the relationship between fat and mortality is more complicated than we tend to evaluate.” Some experts like Steven Blair at the University of South Carolina says this means that being overweight is not as big a broach as we have made it out to be while others such as Walter Willett of Harvard accept the results are “rubbish.”
This debate is likely to act for a while. The Health Blog remembers back in the late 90s when the NIH changed the definition of being overweight from 27.8 to 25 to match international definitions and millions more Americans became overweight overnight. Might these results provoke another discussion of the definition?
