Waist measurement BMI alone is not a good guide to who is at most risk of obesity and cardiovascular disease.
Instead, waist circumference may be a much more accurate measure of future health problems because what matters is where you carry your excess kilos/pounds.
People who are an apple shape - they store fat around their midriff - are far more likely to develop heart disease and diabetes than those who are a pear shape or more diffusely plump.
A waist circumference greater than 80cm (32in) for women and 94cm (37in) for men indicates increased risk, while a measurement of more than 88cm (35in) for women and 102cm (40in) for men is particularly worrying.
Waist-hip ratio An even better measurement of risk may be the ratio of your waist circumference (the narrowest point on your abdomen) to your hip circumference (the widest point).
A ratio of more than 1.0 for a man (in other words your waist is bigger than your hips) or 0.8 for a woman means you urgently need to reduce your weight and increase your levels of exercise.
