Is BMI reliable or valid?
In contrast to other methods, BMI relies solely on height and weight and with access to the proper equipment, individuals can have their BMI routinely measured and calculated with reasonable accuracy. Furthermore, studies have shown that BMI levels correlate with body fat and with future health risks.
Who is BMI not accurate for?
This isn’t the only place where BMI falls apart either. BMI is also not reliable to use on elderly adults, who generally have lost some amount of muscle and bone mass. In this case, an elderly person’s BMI could be within a normal range while they might actually be overweight.

Is BMI chart realistic?
BMI (body mass index), which is based on the height and weight of a person, is an inaccurate measure of body fat content and does not take into account muscle mass, bone density, overall body composition, and racial and sex differences, say researchers from the Perelman School of Medicine, University of Pennsylvania.
What is the best BMI to have?
For most adults, an ideal BMI is in the 18.5 to 24.9 range. For children and young people aged 2 to 18, the BMI calculation takes into account age and gender as well as height and weight. If your BMI is: below 18.5 – you’re in the underweight range.
What should I use instead of BMI?
The BMI and other so-called “field methods”-among them, waist circumference, waist-to-hip ratio, skinfold thicknesses, and bioelectrical impedance-are useful in clinics and community settings, as well as in large research studies.
What happens if your BMI is too low?
Weighing too little can contribute to a weakened immune system, fragile bones and feeling tired. You can check if you’re underweight by using our BMI healthy weight calculator, which shows your body mass index (BMI). If your BMI is below 18.5, this suggests that your weight may be too low.
Why do doctors still use BMI?
Body Mass Index Is a Good Gauge of Body Fat The most basic definition of overweight and obesity is having too much body fat-so much so that it “presents a risk to health.” (1) A reliable way to determine whether a person has too much body fat is to calculate the ratio of their weight to their height squared.
