Is It Time to Say Goodbye to BMI? A Commentary.

The linkage between weight and health is complicated and our current body of evidence is inconsistent. We cannot have a discussion about weight without understanding the larger context of our antifat society and the influence of the diet industrial complex. Weight bias and a focus on weight in health care produce known harms. Additionally, clinicians often recommend losing weight without a nuanced discussion of the evidence showing that most people are unlikely to be successful with sustained weight loss. In this piece, I argue that using our precious time with patients and health care dollars to focus on health behaviors with indisputable evidence such as increasing physical activity and promoting smoking cessation is a more effective use of resources and more closely aligns with our ethical obligation to "do no harm."
