I can describe and calculate the metabolic rate BMI = body mass (kg) (height)2 (m) BMI Conclusion Gloria: 1.45m and 66kg <20 underweight BMI = 31 20-25 normal Zak: 1.85m and 66kg 25-30 overweight BMI = 19 >30 obese What is BMI? Body Mass Index (BMI) measures the relative amounts of fat and muscle in the body. What are their health risks? Obese people have an increased risk of arthritis, diabetes and heart disease. People who are underweight tend to have poor immune systems and often get ill.

I can describe and calculate the metabolic rate Are you right for your height? In 2002, 22% of boys and 28% of girls aged 2-15 in the UK were overweight or obese. Statistics show that obesity levels, among both young people and adults, are rising. Calculating a person’s BMI can be useful, but the formula can overestimate the proportion of body fat in people who are muscular. This is because muscle is denser than fat. This means it is helpful to use extra measures to help judge how healthy a person is, such as waist circumference.
I can describe how different foods contribute differently to the daily intake of calories What is wrong with fast food? Fast food and takeaways such as curries, burgers and pizzas are high in unhealthy nutrients such as saturated animal fats,sugarandsalt. Fast food usually contains very little fibre, vitamins, minerals or unsaturated vegetable oils, which are important for a healthy diet.
