Wait 10 years, a new study says. Odds are, you'll be proven wrong.
New research finds that even when a person is "metabolically healthy," being obese raises his or her risk for cardiovascular disease and premature
The meta-analysis - a study that aggregates the findings of many well-designed studies in an effort to distill larger truths - appears to dash hopes that for some,
Those findings had fueled resistance to the nationwide assault on obesity from those who argued they were "fat but fit."
The latest study does less damage to the growing suspicion that it's OK to be
But even those findings left the question open: There was a trend in that direction. But it was not so robust that the researchers could be confident it wasn't a statistical fluke.
In the end, that trend may be the most significant finding of all. When researchers used BMI to line up all of the 61,386 subjects who participated in the eight studies they pooled, they found that, as BMI rose, so rose blood pressure, waist circumference and insulin resistance. As BMI increased, levels of HDL cholesterol, thought to protect against heart attack and stroke, decreased. Though overweight and obese subjects may not yet have reached the points that define metabolic illness, they appeared to be on that road as their weight rose.
"Increased BMI is not a benign condition, even in the absence of metabolic abnormalities," the authors said.
Take note, however. The newest study does not give "normal weight" people a pass if they are metabolically unhealthy. In this aggregation of subjects from many different studies, the authors found that this group is just as likely as those who are obese and metabolically unhealthy to have
