But how big is big? When does that size move from big to overweight, to obese? When does it become a concern for your health?
A new study looks at the different weight definitions and how they each play a role in disease and morbidity. It turns out that obese is bad news. But overweight may be okay.
The study in the Journal of the American Medical Association, or JAMA, finds that obesity was linked to about 11 percent of deaths from cancers such as breast, kidney, colon or pancreatic cancer. Obesity was linked to about nine percent of cardiovascular deaths. But among those who are classified as overweight but not obese, there was no death sentence from cancer or cardiovascular disease.
"We define obesity as a body mass index of 30 and above. We define normal weight as a body mass index of 18.5 to 25 and overweight is the intermediate category from 25 up to 30." said Katherin Flegal, PhD. with the Centers for Disease and Prevention.
The CDC uses body mass index, or BMI, which is essentially your weight divided by your height squared.
