Your weight does not equal your measure of health - new research
I love to see research that demonstrates that our beliefs about being overweight = unhealthy are just not true. This New York Times article talks about the newest research on weight versus health. I consider this as one more step toward the ending of discrimination against fat people!

"Better to Be Fat and Fit Than Skinny and Unfit
Often, a visit to the doctor’s office starts with a weigh-in. But is a person’s weight really a reliable indicator of overall health?
Increasingly, medical research is showing that it isn’t. Despite concerns about an obesity epidemic, there is growing evidence that our obsession about weight as a primary measure of health may be misguided.
Last week a report in The Archives of Internal Medicine compared weight and cardiovascular risk factors among a representative sample of more than 5,400 adults. The data suggest that half of overweight people and one-third of obese people are “metabolically healthy.” That means that despite their excess pounds, many overweight and obese adults have healthy levels of “good” cholesterol, blood pressure, blood glucose and other risks for heart disease.
At the same time, about one out of four slim people — those who fall into the “healthy” weight range — actually have at least two cardiovascular risk factors typically associated with obesity, the study showed.
“We use ‘overweight’ almost indiscriminately sometimes,” said MaryFran Sowers, a co-author of the study and professor of epidemiology at the University of Michigan. “But there is lots of individual variation within that, and we need to be cognizant of that as we think about what our health messages should be.”
The data follow a report last fall from researchers at the Centers for Disease Control and Prevention and the National Cancer Institute showing that overweight people appear to have longer life expectancies than so-called normal weight adults.
But many people resist the notion that people who are overweight or obese can be healthy. Several prominent health researchers have criticized the findings from the C.D.C. researchers as misleading, noting that mortality statistics don’t reflect the poor quality of life and suffering obesity can cause. And on the Internet, various blog posters, including readers of the Times’s Well blog, have argued that the data are deceptive, masking the fact that far more overweight and obese people are at higher cardiovascular risk than thin people.
Part of the problem may be our skewed perception of what it means to be
overweight.
“People get confused by the words and the mental image they get,” said Katherine Flegal, senior research scientist at the C.D.C.’s National Center for Health Statistics. “People may think, ‘How could it be that a person who is so huge wouldn’t have health problems?’ But people with B.M.I.’s of 25 are pretty unremarkable.”
Several studies from researchers at the Cooper Institute in Dallas have shown that fitness — determined by how a person performs on a treadmill — is a far better indicator of health than body mass index. In several studies, the researchers have shown that people who are fat but can still keep up on treadmill tests have much lower heart risk than people who are slim and unfit.
The results were adjusted to control for age, smoking and underlying heart problems and still showed that fitness, not weight, was most important in predicting mortality risk.
“Why is it such a stretch of the imagination,” he said, “to consider that someone overweight or obese might actually be healthy and fit?”
