Q:  I want to lose weight, and have been told that it is best to use my BMI (body mass index) as a measure of progress.  Can you show me how I could use my computer to work out the figure and keep it updated as a diet? 

A:  Spreadsheets such as Excel are excellent for doing complicated sums and monitoring changes, as long as you can provide the correct formulae. Instead of relying on actual weight, you can keep track of your healthy weight by working out your BMI.

For new dieters, the international classification for BMI is:

Below 20 – underweight

20 – 25 – acceptable weight

25 – 30 – overweight

30 – 40 – obese

Over 40 – very obese 

Here is what you would need to do to work out your BMI on paper:

  • Express your current weight in kilograms. (If you weigh yourself in imperial units, you need to divide the pounds by 2.2)

Example:  if you weigh 10st 2 lbs, as there are 14lbs in 1st, your total weight in lbs is (10 x 14) + 2 = 142lbs.  Divide by 2.2 and this becomes 64.5kg

  • Express your current heightin metres.  If you measure this in inches, you must multiply the figure by 0.025.

Example:  if you are 5ft  5”, there are 12” in 1ft and so your heightis (5 x 12) + 5 = 65”.  Multiply by 0.025 and this becomes 1.6m. 

  • Square your height. = 1.6 x 1.6 = 2.6

  • Divide your weight by your squared height. i.e. 64.5/2.6 = 24 BMI

 

 

In Excel, you need to set out the details as follows: 

The actual values will be: 

As you lose weight, change the figures in cells A3 and B3 and the final BMI will instantly change.
