1. BMI health check • Aim of activityTo understand what is a healthy Body Mass Index (BMI) score, how to calculate your own, and the role of exercise and diet on your BMI. • Live Long & Prosper themeHealthy living • Skills for Life coveredNumeracy • Learning outcomesBy the end of the session, participants will be able to: • Explain what Body Mass Index means and why it matters • Calculate their own BMI score and know whether this is within the healthy range – and the implications if it is too high or too low • Use the resources given to work out a plan of action to change their BMI to within the healthy range • Resources requiredWeighing scales and tape measure (metric) • Pen and paper (for noting numbers) • Rulers or other flat-edged object (to read off scores on a chart) • Calculator • BMI chart – available online at www.food.gov.uk/multimedia/bigimages/heightweightfull.jpg • An inflatable toy and a picture of a heavy garden ornament • Flip chart • Introduction: What BMI means and why it’s useful (5 minutes) • Go through the learning outcomes. • Explain what BMI means and why it’s useful using the ‘BMI health check fact sheet’.

2. BMI health check Main content: How to work out a BMI (15minutes) Give a light hearted demonstration of the BMI calculation. 1. Measure the inflatable toy’s height in metres – write on flip chart 2. Multiply the figure by itself – this is the height squared – write on flip chart 3. Measure the dolls weight in kilograms – write on flip chart 4. Divide the weight by the height squared – step 3 divided by step 2 E.g. if the toy is 1.10m tall and weighs 3 kg the calculation is: 1.10 x 1.10 = 1.21 3kg divided by 1.21 = 2.5 – a worryingly low BMI Show everyone on the chart how concerned you are about the inflatable toy and point out some of the problems associated with being very underweight. Refer to handout. Using the picture, repeat the process for the garden ornament. If the garden ornament is 1m tall and weighs 50kg the calculation is 1 x 1 = 1 50 kg divided by 1 = 50 = 50 – an incredibly high BMI Oh dear, the garden ornament is in trouble. Point out the serious health issues about being so overweight. Refer to handout. Top Tip!Practice your calculations first and have them written out, as it can be very difficult to remember when you have lots of eager faces looking at you! If you are feeling brave, now demonstrate the calculation with your own weight or height! If participants feel comfortable doing so, give them the opportunity to work out their own BMI. Encourage people to work in metres and kilograms, although most charts have both metric and imperial measurements. Have tapes and weighing scales handy if measurements need to be checked. Help people with any calculations needed. NB: Many people may be self-conscious and may not want to weigh themselves in public. The handout has instructions to take home.  Simple Conversions1 stone = 6.5kg 1 inch = 2.5cm1 foot = 30cm 1 pound = .5 kg
