scales specifically designed to track your weight with various indicators
including your BMI*.
* BMI = Body Mass Index.
The BMI measures the weight status of a person. It is used by the World
Health Organization (WHO) to assess risks caused by overweight or
anorexia in relation to a reference scale.
BMI is calculated as follows:
weight in kilograms / (height in metres x height in metres).
For example, for a person weighing 62 kg and 1.60 metres tall:
The BMI is 24.2.
Tefal and Weight Watchers bring you bathroom scales that automatically
calculate your BMI and interpret it to help you track your weight better.
