(August 12, 2008)--A new study shows people can be overweight and still be otherwise healthy, and it also finds that people who look great in a swimsuit may be among the ones most at risk of heart attacks.
The study found about half of overweight adults have mostly normal levels of blood pressure, cholesterol, blood fats called triglycerides and blood sugar and that almost one-third of adults who are considered obese are also in that healthy range.
That totals about 56 million people.
The study's author says it's no secret that thin people can have heart-related problems and that fat people often do not, but the fact that millions defy the stereotypes may come as a surprise.
The results also add to mounting evidence that thick waists, even on people of normal weight, can be a signal of heart risks.
The study appeared in the Archives of Internal Medicine.
