What are the disadvantages of BMI?
Disadvantages of BMI
BMI is a simple mathematical formula that measures body fat based on your height and weight. It does not take into account the source of the weight – whether it is from lean tissue or fat. BMI does not distinguish between the type of fat one carries – whether it is subcutaneous or visceral fat.
What is the advantage of using a BMI chart?
Another key advantage of using BMI for determining weight-related health risk is that the measures needed for its calculation — height and weight — can be taken with high accuracy when performed using standardized procedures. These procedures are easy to follow and can be applied with minimal technician training.
What is the most significant disadvantage of using BMI to assess body composition?
The clinical limitations of BMI should be considered. BMI is a surrogate measure of body fatness because it is a measure of excess weight rather than excess body fat. … Also, BMI does not distinguish between excess fat, muscle, or bone mass, nor does it provide any indication of the distribution of fat among individuals.
What are the strengths and limitations of using BMI as a measure?
The strengths include the fact that BMI is cheap and relatively easy to use. The weaknesses include the fact that BMI percentiles are not widely used, and categorization of BMI percentiles may not adequately define risk of comorbid conditions.
What is the correct BMI for my age?
A BMI of between 18.5 and 24.9 is ideal. A BMI of between 25 and 29.9 is overweight. A BMI over 30 indicates obesity.
Does BMI increase with age?

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.
Is a BMI of 26 OK?
Someone with a BMI of 26 to 27 is about 20 percent overweight, which is generally believed to carry moderate health risks. A BMI of 30 and higher is considered obese. The higher the BMI, the greater the risk of developing additional health problems. A healthy weight is considered to be a BMI of 24 or less.
Is BMI a good health indicator?
As a single measure, BMI is clearly not a perfect measure of health. But it’s still a useful starting point for important conditions that become more likely when a person is overweight or obese.
How will you improve your BMI results?
Avoid food that is high in sugar, like pastries, sweetened cereal, and soda or fruit-flavored drinks. Reduced-fat or no-fat (skim) milk, reduced-fat cheese, and low-fat or no-fat yoghurt are good sources of the protein and calcium we need. Try to eat 2-4 servings of low-fat or no-fat dairy products each day.
Why BMI is inaccurate and misleading?
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 measure of obesity?
- The most basic method, and the most common, is the body mass index (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 are the benefits and potential problems of using BMI as a health measure?
Body Mass Index (BMI)
BMI is an estimate of body fat and a good gauge of your risk for diseases that can occur with more body fat. The higher your BMI, the higher your risk for certain diseases such as heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems, and certain cancers.
