Study finds those who are fat but fit still have increased risk of heart disease

Researchers found a higher heart disease rate among people who are obese

Researchers analyzed thousands of cases of coronary heart disease over more than 12 years in 10 countries in Europe. They found that being overweight or obese was associated with a more than 25 percent higher risk of developing coronary heart disease than being at a healthy weight, even among those who did not have any other markers that reflected an increased risk of heart disease.

Dr. Jennifer Ashton, ABC News' chief medical correspondent, said the research shows that even if people appear healthy based on blood tests today, the risk of health complications can increase over time if they are obese.
