Waist Ratio

As well as BMI, the waist measurement can be an important indicator. There are two important ratios that have been established as reliable indicators of overweight risk:

• waist to height should be less than 0.5 (half)
• waist to hip should be less than 0.8 (women) or less than 1 in men.

People with ratios above these values are at increased health risk because of their fat distribution.

Your waist measurement can become an important motivator during the weight loss phase, especially if you had not lost any weight because of fluid retention. In this scenario, regular waist measurements will confirm that inches - if not kilos - are still being lost!

The Ashwell® Shape Chart has been developed by Dr Margaret Ashwell who is the Nutritional Consultant to Cambridge Health & Weight Plan Limited.

Her research - based on scientific and medical evidence from the Universities of Cambridge and London in the UK - indicates that health risk could be determined by the shape of people's bodies (see below).

Apples
Excess fat which is found deep down in the region of the stomach and gives someone an 'apple' shape, is often associated with serious conditions such as heart disease, raised blood pressure, diabetes and some types of cancer.

Pears
Excess fat which is found under the skin, around the bottom, hips and thighs and gives a 'pear' shape is less harmful to health..

What to do:

  1. 'Draw' a horizontal line corresponding to your height.
  2. 'Draw' a vertical line to correspond to your smallest waist circumference measurement.
  3. The point where these two lines meet shows where your shape is on the chart.

What it means:

If your shape is in the orange ‘chilli’ region, you should take care. You will not need to lose weight, and might need to gain it.

If your shape is in the green ‘pear’ region, you have a healthy OK shape.

If you shape falls in the yellow ‘pear-apple’ region, (particularly the upper end), you should Take Care. Make certain that you don’t put on any more weight which will increase your waistline.

If your shape falls in the red ‘apple’ region, your health is probably at risk. You should talk with your GP about losing weight. Your waistline will then decrease and your health risk too.
