Weight: there is no magic number, but there is a healthy range

There’s a lot of talk out there about staying at a ‘healthy’ weight. But what does that mean exactly? There is no perfect measure of weight, or way to determine if one is overweight – but the Body Mass Index (BMI) is considered the standard test to determine if you’re within a healthy weight range. A BMI test is measured by your height and weight, and you can calculate it yourself.

Calculating your BMI

Calculating your BMI is easy. First, take your weight and height measurements in kilograms and metres. Divide your weight in kilograms by your height in metres squared.
For example:
Weight = 60 kg
Height= 1.7 m (1.7 x 1.7 = 2.89 m2)
BMI = 60 / 2.89 = 20.7

Compare your BMI to the chart to see which range you fall into.


Manage your weight with serving size

A healthy weight is the result of a balanced diet and exercise, which involve many factors. One of the biggest that can throw you off course is food serving sizes. It’s easy to eat more sugar or sodium than you realise if you don’t know what the recommended serving size is or what it means.

The best way to stick to recommended serving sizes is to become confident at reading labels. Study the package before you serve yourself a portion, so you know whether you’re eating one serving – or five. For example, a nutritional claim could be made on a serving of 30g of cereal, but you or your child might eat two or three servings for breakfast. Having the right information means you can keep your portions – and your weight – in check.
