Why are Drs. Roizen and Oz so focused on waist size, not weight?
Because pounds only tell you how hefty you are. They don't say a thing
about how healthy you are. Waist size does—belly fat is linked to multiple
medical problems. So does body mass index, or BMI, a height/weight measure
that estimates body fat. The healthier these numbers are, the healthier you are,
especially in terms of cardiovascular disease and diabetes.
