The Body Mass Index

You may decide that you want to lose weight but are not sure how much to aim for. Don’t just base it on vanity but aim for a weight that is healthy for your height. Your body mass index (BMI) gives you the relationship between height and body weight. This can be worked out using the following formula:

 BMI = ___Body weight (kg)__  

          Height (m) X Height (m)                                          1ft = 0.3m            1 stone = 6.35kg

                                                                                          1 in = 0.025m     1 lb = 0.45m

Description	BMI
Underweight	20 or less
Healthy	20 – 25
Overweight	25 – 30
Obese	Over 30

However, do bear in mind, muscle is heavier than fat, so the reading can be inaccurate for very muscular people.

You can also find BMI charts online, which will work it out for you.
