Fat is also the new healthy:http://www.nytimes.com/2007/11/07/health/07fat.html
"About two years ago, a group of federal researchers reported that overweight people have a lower death rate than people who are normal weight, underweight or obese. Now, investigating further, they found out which diseases are more likely to lead to death in each weight group.
Linking, for the first time, causes of death to specific weights, they report that overweight people have a lower death rate because they are much less likely to die from a grab bag of diseases that includes Alzheimer’s and Parkinson’s, infections and lung disease. And that lower risk is not counteracted by increased risks of dying from any other disease, including cancer, diabetes or heart disease.
As a consequence, the group from the Centers for Disease Control and Prevention and the National Cancer Institute reports, there were more than 100,000 fewer deaths among the overweight in 2004, the most recent year for which data were available, than would have expected if those people had been of normal weight.
Their paper is published today in the Journal of the American Medical Association.
The researchers also confirmed that obese people and people whose weights are below normal have higher death rates than people of normal weight. But, when they asked why, they found that the reasons were different for the different weight categories.
Some who studied the relation between weight and health said the nation might want to reconsider what are ideal weights.
“If we use the criteria of mortality, then the term ‘overweight’ is a misnomer,” said Daniel McGee, professor of statistics at Florida State University.
“I believe the data,” said Dr. Elizabeth Barrett-Connor, a professor of family and preventive medicine at the University of California, San Diego. A body mass index of 25 to 30, the so-called overweight range, “may be optimal,” she said."
