The key to good health: Maintain a waistline less than half of your height

 it may be important to measure your waist to less than half your height,

rather than just measuring body mass index (BMI).

A high buildup of fat around the waist, called "central fat,

" is a major cause of increased risk of type 2 diabetes

high blood pressure, heart disease and stroke.

It may be more useful to measure the waist-to-height ratio rather than just BMI because BMI does

not take into account excess weight around the abdomen. They are also

not accurate in people with a BMI over 35, pregnant women or children under the age of two, the BBC reported.
