Body Weight - Is your weight harming your health?

Start by calculating your body mass index (BMI) to assess whether you are the right weight for your height and sex.
A healthy bodyweight range is defined as a BMI of between 18.5 and 25.
A BMI below 18.5 is underweight.
Between 25 and 30 is overweight.
Between 30 and 35 is obese.
A BMI of 40 and above is morbidly obese.
BMI is only an indication of total bodyweight and tells little about the proportion of muscle to fat mass.

Athletes and bodybuilders who have a greater than average muscle mass will have an optimum weight that's higher than the healthy range.

How to calculate your BMI?
take your weight (kg) and divide it by the square of your height (m).
For example, if you weigh 80kg and are 1.7m:

1. Multiply your height by itself 1.7x1.7=2.89
2. Divide your weight by this figure.
3. 80 ÷ 2.89= 27.7.
27.7 is the BMI
