Not really a new idea for many of us, but the American Medical Association (AMA) has finally acknowledged that the Body Mass Index (BMI) in itself is an insufficient and inaccurate screening tool to assess health. While it’s useful for large scale studies of various populations, it has serious limitations when used to evaluate and categorize individuals.
“it’s taken on outsized significance for individuals, even sometimes called a ‘scarlet letter.’
‘It is noted in every medical record,’ said Dr. Jamy Ard, a professor of epidemiology and prevention at the Wake Forest University School of Medicine. ‘It is part of the consideration for life insurance; your employer may use BMI to offer certain wellness programs to you.’
BMI is used to determine eligibility for weight loss medications, and it can affect access to joint-replacement surgery and fertility treatment.
‘It is easy to calculate and essentially costs nothing,’ Ard wrote in an email, ‘so this makes it very hard to replace’” (1).
I find this all very interesting on a personal level because I’ve twice been told that I could safely stop losing weight, by two different doctors. The first time, my BMI was 27 and the second was 25.5 – both are in the overweight category. And if you look at the graph below, you will see that there is no clear advantage to a BMI lower than 25.

It’s concerning to read that people may be denied treatment for some conditions due to BMI status. I can understand that surgeries may be riskier if you are unhealthy, but that’s what preoperative testing is for. A number on a scale should not be the gatekeeper. And as we can see in the graph, a little extra weight may actually be associated with lower risk of death!
Here’s an informative video that explains why BMI is not the best standard for assessing health (3):
You may have heard that there is possibly a racist component to BMI. This is something that is basically baked into this data, because BMI measurements were originally gathered disproportionately on non- Hispanic white people (4). If large groups of people are not properly included in the data set, how can we apply the results to them?
There are many other measures that are better assessments of an individual’s health “including waist circumference, body fat percentage, blood pressure, cholesterol levels, and lifestyle habits” (5). According to Physicians News Digest, health is not an one size fits all proposition (5). We are individuals who deserve treatments that are customized to our personal health needs.
As you are likely aware, I am not a medical professional. Because of this, I can only suggest that you see your own medical provider to assess the risks that your body composition poses to your health. It is always best to seek advice from them, not only because of their training, but also because they understand your medical history. Working with your provider is the surest way to advance your health!
