“Great News – My BMI tells me I am underweight …
… I should be 21 feet tall”
BMI or Body Mass Index is a very crude method of determining if your weight is appropriate for your height. The actual calculation is your weight (in kilograms) divided by your height (in metres) squared but it’s also easy to read on the chart. BMI values are often grouped into several categories to allow.
BMI charts are calculated for adults only (separate charts are available for children’s weight and heights). Inaccuracies can also occur if you’re an athlete or very muscular as this can give you a higher BMI even if you have a healthy level of body fat and BMI is not suitable for women who are pregnant or breastfeeding or those who are very frail.
As BMI is based on weight and height, by losing weight you will reduce your BMI and put yourself into a lower risk group. A healthy diet, including a balance of food groups, vitamins and minerals, is essential for a long and active life. Keeping it simple, body weight and shape are a balance of energy intake (dietary calorific content) against output (calorific burn from activity & exercise).
