Body mass index: Why practitioners are relying on it less when looking at a patient’s health

Body mass index has long been used by doctors as the standard method for measuring health—and often still is. But earlier this month, the American Medical Association (AMA) adopted a new policy that cautions medical professionals from using the body mass index (BMI) as a stand-alone clinical tool during patient consultations. In 2022, England’s National Institute for Health and Care Excellence (Nice) also made similar changes to obesity guidelines, recommending that waist-to-hip ratio be used alongside BMI.
