April 21, 2025 — It is really easy to beat up on the lowly BMI. The Lancet Commission on clinical obesity gently kicked it to the curb by saying BMI “can both overestimate and underestimate adiposity” and thus declared its obsolescence as a singular measure for excess adiposity. “Excess adiposity should be confirmed by either direct measurement of body […]
March 18, 2025 — We’ve been living with the consensus report of the Lancet Commission on Clinical Obesity now for two months. Enough time has passed for feelings about the strengths and limitations of this work to take shape. A new commentary in the BMJ yesterday brings a sharp focus to the struggle of defining and dealing with current […]
February 15, 2025 — It would be hard to dispute that we are living in an age of cynicism. Distrust is all around – especially when the subject is health. Thus, it should not be a surprise that consensus about diagnosing obesity turns out to be quite a challenge. And yet, we are surprised that a global consensus on […]
January 28, 2025 — It is fascinating to watch the public discourse about newly proposed criteria from the Lancet Commission for a clinical diagnosis of obesity unfold. The headline is easy. “It’s time to move beyond BMI alone.” The response to that idea has been clear and unmistakable: “What took so long?” But then comes the hard part that […]
January 23, 2025 — It was easy to see this coming. Our top prediction for the new year was that the Lancet Commission on Clinical Obesity would be big news and the spark for a big debate. The news splash was unmistakable. From 92 countries all over the world, more than 3,000 persons lined up for the launch event. […]
January 15, 2025 — We’ve been waiting for this. And judging by the initial responses, the world is ready for it. The Lancet Commission on Clinical Obesity has made it official: The clinical disease of obesity is all about health. Not size, not appearance, not BMI. This global consensus report published at long last late yesterday in Lancet Diabetes […]
January 4, 2025 — The ongoing debate about the clinical definition of obesity is soon to get more intense. But already, it tells us pretty clearly that obesity is defined by more than excess weight. New research in Nature Medicine comes at this subject from an entirely different direction. Using proteomics, Lasse Maretty and colleagues find that the effects […]
July 24, 2024 — It’s nice, really. People are paying attention to obesity, its definition, and the bias they bring to the subject. If you need evidence of this, look no further than a series of three new editorials in the Annals of Internal Medicine. They’re wrestling with BMI and the definition of obesity. The authors present a range […]
May 15, 2024 — The symposium that packed an auditorium at ECO2024 yesterday dealt with the fundamental need to get beyond BMI for defining clinical obesity. It seems so simple. “Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health,” says the World Health Organization. And yet that definition ties back to BMI for […]
April 9, 2024 — More than a decade has passed since the American Medical Association confirmed that obesity is a complex, chronic disease. But the rest of the world is still struggling with this idea. Much as we have all started to say obesity is a disease, we more often act like it’s merely a risk factor for other […]
