BMI is a useful measure of overweight and obesity. It is calculated from your height and weight. BMI is an estimate of body fat and a good gauge of your risk for diseases that can occur with more body fat.
How good is BMI as an indicator of health?
BMI is a reasonable indicator of body fat for both adults and children. Because BMI does not measure body fat directly, it should not be used as a diagnostic tool. Instead, BMI should be used as a measure to track weight status in populations and as a screening tool to identify potential weight problems in individuals.
Why is BMI not always the best indicator of overall health?
BMI provides an estimate of a person’s overall disease risk, and is used around the world to measure obesity. But BMI has come under criticism because it can be inaccurate in estimating body fat and doesn’t provide a full picture of a person’s health.
Is BMI The best measurement of obesity and an accurate indicator of health?
Beyond assigning one of these categories, a high BMI can be also an indicator of high body fat and therefore can be used to screen for certain weight levels that could lead to health problems. Even though it is often used as one, it is not a true diagnostic of body fatness or of an individual’s overall health.
Why is BMI a bad health indicator?
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.
Is WHR a better indicator than BMI?
WHR is an easy, inexpensive, and accurate way to see how much body fat you have. It can also help predict your risk for heart disease and diabetes. A few studies suggest that WHR is even more accurate than BMI for predicting the risks of cardiovascular disease and premature death .
Why weight is not a good health indicator?
Myth #3: Fatter bodies are inherently less healthy, and have a higher risk of disease and mortality. There is no evidence to support that body weight alone is a risk factor for disease or higher mortality. … However, there is no evidence to suggest that excess weight causes disease.
What is more accurate than BMI?
Waist-to-height ratio more accurate than BMI in identifying obesity, new study shows. Summary: Calculating a person’s waist-to-height ratio is the most accurate and efficient way of identifying whether or not they are at risk of obesity in clinical practice, a new study shows.
Do doctors still use BMI?
It is used in population studies, by doctors, personal trainers, and others. However, BMI has some important flaws. For example, it does not measure overall fat or lean tissue (muscle) content. BMI is derived from a simple math formula.
Is lower BMI better?
If your BMI is less than 18.5, it falls within the underweight range. If your BMI is 18.5 to 24.9, it falls within the normal or Healthy Weight range. If your BMI is 25.0 to 29.9, it falls within the overweight range. If your BMI is 30.0 or higher, it falls within the obese range.
What is the most accurate measure of obesity?
BMI remains the most commonly used, widely accepted, and practical measure of obesity in both children and adults, particularly for surveillance.
What are the disadvantages of BMI?
Since muscle weighs more than fat, BMI isn’t accurate in patients with extreme amounts of muscle. And this can cause unnecessary concern or a faulty sense of security for many adults. For example, a fit person with dense muscle could be categorized as overweight based on BMI.
Is BMI The only way to determine obesity?
Estimations of body fat beyond BMI include measurements with calipers and waist-to-hip ratio measurements. However inaccurate, BMI is the most convenient way to classify body fat mass and obesity. There are, on the other hand, better methods to measure whole body fat levels.
