Waist to hip ratio is the measurement that warns of obesity and cardiovascular disease (CVD).
Studies suggested that waist circumference and waist-to-hip ratio are better indicators of the risk of diabetes than BMI (Body Mass Index).
If the waist circumference is more, the risk for heart disease is more, even if the body weight is less and vice versa.
The most common shape in female is gynoid shape (pear shape), in which, the excess fat deposits on hips and buttocks (gluteo-femoral region) causing lesser health risk.
On the other hand, the android shape (apple shape) causes serious health problems due to the fat deposition on subcutaneous (beneath the skin) truncal-abdominal region (middle-section of the body) and is common in male population.
