What is a Healthy Weight?
Doctors check your body size by measuring your height and weight- a measure known as body mass index. Research shows that people within a certain range of body sizes are likely to live longer and enjoy better health.
To calculate your body mass index (BMI):
•Work out your height in metres (or inches) and multiply the
figure by itself (= your height squared)
•Measure your weight in kilograms (or lbs)
- divide your weight by your height squared to reach your BMI rating
If you are 1.6m (5 feet 3 inches) tall and weigh 65 kg (10
1.6 x 1.6 = 2.56. BMI would be 65 divided by 2.56 = 25.39
BMI ranges are as follows*:
Less than 19 Underweight
Over 40 Very obese
*BMI is not as accurate if you are an athlete or very muscular as muscle weighs more than fat
Another way of assessing whether you are a healthy weight is your waist measurement. As a woman you should not gain any more weight if your waist measures 32 inches (80 cm). A man should not gain any more weight if the waist measurement is 37 inches (94 cm). In both cases losing 3 inches off the waist measurement would be nearer to the ideal measurement.
