Furthermore, a low BMI below That said, BMI fails to consider other aspects of health, such as age, sex, fat mass, muscle mass , race, genetics, and medical history.
Though BMI can be useful as a starting point, it should not be the only measurement of your health. Body fat scales can be an easy way to track your body fat percentage, but they may not tell the complete story about your health.
Accuracy can also…. There are many methods you can use to measure body fat, but some are more reliable than others. Muscle mass is a part of your lean body mass. The most accurate methods are…. Figuring out how much you should weigh for your height and age is more complicated than it sounds. Does muscle really weigh more than fat? For now, BMI is going nowhere.
But this study, along with others that call for a health-prediction scale with more nuance, may be chipping away at the…. Focusing on body fat percentage instead of weight is much more useful to track fat loss progress. Here are the 10 best ways to measure your body fat…. Health Conditions Discover Plan Connect.
What is BMI? BMI range Classification Risk of poor health less than Is it a good indicator of health? Downsides of BMI. BMI range Classification less than Better alternatives. The bottom line. Read this next. Medically reviewed by Elaine K. However, it fails to take into account the thickness of a person. Which quite simply comes down to the assumption of you being two dimensional, which is not the case. These 4 main reasons clearly outline why BMI is fundamentally wrong. It has been proven to be a much better indicator of mortality risk by the Journal of Translational Medicine.
And this is exactly why ShapeScale also uses Shape Index to make predictions based on your body shape. It uses WC in its equation, which is a proxy for abdominal fat distribution. As mentioned earlier, abdominal fat carries several health risks and therefore, is important to consider.
Source: The New York Times. As the Illustration shows, people with the same height, but different fat distribution can have the exact same BMIs. However, their WCs and therefore, Shape Indexes will not be the same. Due to the previously mentioned health risks, WC has been found to be a better predictor of mortality than BMI by several studies. However, on its own WC is not a perfect measure either.
The classification of WC is different for men and women, but not for people with different height. Yet, as you get taller, your waist circumference is likely to get greater as well. Another significant drawback of BMI is the lack of differentiation across genders and age groups. In contrast, Shape Index has a control over age and gender variation.
This makes Shape Index a better predictor of body fat and ultimately of the risk of mortality. So to sum up everything, BMI is a misleading indicator of obesity. Several influential factors, such as weight distribution and gender are left out from its calculations, which make the BMI predictions of mortality unreliable. Waist Circumference is already seen to be a better predictor however, it has some drawbacks as well. Overall, a new measurement, Shape Index is thought to be a much better indicator of obesity and health risks.
Therefore, ShapeScale will also use this index to provide feedback on your body shape. Facebook Twitter WhatsApp. What is BMI?
