Why to choose BIA over BMI

Many of us considering measuring how healthy our weight is will start by calculating our Body Mass Index (BMI.)

However, BMI is worked out as someone’s weight divided by their height squared. BMI does not measure how much excess fat we hold opposed to bone and muscle or vice versa. This is why some sporty people like rugby players, body builders or weightlifters for example may be incorrectly classified as having an unhealthy BMI and someone who looks thin on the outside though is actually fat on the inside has a BMI sitting in the healthy zone.

Measuring body composition through Bioelectrical Impedance Analysis (BIA), on the other hand, is a far more effective way to analyse body measurements including body fat , lean mass, levels of hydration as will as daily energy requirement (calories) and basal metabolic rate (BMR)

So, if you are looking to improve your health and fitness, it may be better to focus on body composition via BIA over BMI.

Though your bathroom scales may have basic BIA technology built in due to the thickness of the soles of the feet they do not give you the best results. The best and most accurate forms of BIA are available from professionals such as Nina Thomas, Registered Nutritionist at Bridgford & Bingham Nutrition.
