As stated, BMI helps measure the obesity rate in people. Observing the changes in BMI values help the doctors evaluate the obesity levels in people over time. When the BMI of a significant population is calculated, it helps researchers gather data that can be used to examine the obesity epidemic.
What is the advantage of BMI?
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.
Is BMI a good health indicator?
BMI is a useful indicator of health at the population level. However, the distribution of fat on your body is more important that the amount, when assessing your disease risk. For this reason, your waist circumference is thought to be a better predictor of health risk than your BMI.
What does the BMI tell you?
What’s Your Body Mass Index (BMI)? BMI is a way to figure out your approximate level of body fat in an easy, inexpensive way. It’s a number based on your weight and height that can help you tell if you are at a healthy weight for your height. In general, the higher the number, the more body fat a person has.
What is a disadvantage of BMI?
BMI Doesn’t Account For Body Composition
The first — and biggest — disadvantage of BMI is that it doesn’t account for body composition. This means that if you’re very lean or muscular, your BMI results may not provide an accurate picture of your general health.
What are the weaknesses of BMI?
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 best BMI for a woman?
A BMI of 18.5–24.9 is considered normal or healthy for most women.
Why do doctors still use BMI?
Body mass index, or BMI, has been used for over 100 years to help health professionals decide whether a patient is overweight or underweight. It is used in population studies, by doctors, personal trainers, and others.
What is my ideal weight?
Weight and height guide chart

|5ft 1″ (61″)||100 to 127 lbs.||132 to 153 lbs.|
Is a BMI of 25% good?
below 18.5 – you’re in the underweight range. between 18.5 and 24.9 – you’re in the healthy weight range. between 25 and 29.9 – you’re in the overweight range. between 30 and 39.9 – you’re in the obese range.
What BMI Cannot tell you?
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.
Does BMI actually matter?
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.
What BMI indicates a normal weight?
How is BMI interpreted for adults?
|18.5 – 24.9||Normal or Healthy Weight|
|25.0 – 29.9||Overweight|
|30.0 and Above||Obese|
Does BMI increase with age?
For adults ages 20 years and older, BMI incorporates weight and height, but it does not take age or sex into account. A woman tends to have more body fat than a man with the same BMI. Likewise, an older person tends to have more body fat than a younger person with an equal BMI.
Why is the BMI so inaccurate?
A glob of muscle weighs about 18 percent more than the same size glob of fat. So, according to the BMI, the sprinter is more overweight than the sedentary person. But as I said earlier, a glob of muscle weighs about 18 percent more than the same size glob of fat, so this is clearly not an accurate statement.
