Has the Obsolescence of BMI for Screening Been Overstated?

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 […]

Mixing Food Noise, Addiction, and Ultra-Processed Foods

March 8, 2025 — “It takes years for scientists to prove things we’ve always known were true – like food addiction.” This thought emerged from the meeting this week of the Roundtable on Obesity Solutions.

What Is Hard About a Clinical Diagnosis of Obesity?

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 […]

A Rise in Unreasonable Doubts About Health Science

December 29, 2024 — In recent years, a troubling trend has emerged – a growing distrust in health science, particularly in fields like nutrition and obesity.

In the age of social media and viral misinformation, unreasonable doubts have real consequences […]

The Enduring Fascination with Causal Pathways for Obesity

August 23, 2024 — A new paper this week reminds us of the enduring fascination with causal pathways for obesity. Why has the prevalence grown so relentlessly? How can we reverse it? This preoccupation has been the source of controversy and mistakes in dealing with obesity. One of the more memorable controversies is the back-and-forth debates between David Ludwig […]

Truth and Light, Carbs and Insulin, Trading Letters in Obesity

May 17, 2024 — “Give a boy a hammer and everything he meets has to be pounded.” Though this hammer-nail-pounding metaphor started half a century ago, it still works well today. For example, folks armed with the carbohydrate insulin model (CIM) of obesity see opportunities everywhere to pound away, bringing truth and light. Whatever the question, carbs and insulin […]

The Tension Between Cynicism, Skepticism, and Pragmatism

February 25, 2024 — Are we cynical? We can surely find excuses to be. Examples of cynicism pop up at every glance. Certainly we see it in politics and public policy. Closer to home at ConscienHealth, people routinely find reasons for cynicism about all kinds of medical research and advice – especially nutrition and obesity. This is a real […]

The Overwhelming Appeal of Simplistic Obesity Thinking

August 24, 2023 — Simplistic thinking about obesity has an overwhelming appeal. Sadly, though, it has a dismal history of letting us down. “Yes, calories in/calories out really is the key to weight loss,” writes Tamar Haspel in the Washington Post. To insure we don’t miss the point, she closes by saying: “It’s the calories, people. It’s the calories.” […]

AMA Takes a Swipe at Misuse of the Feeble BMI

June 15, 2023 — BMI seems to be everyone’s favorite target for abuse these days. Depending on whom you listen to, it’s racist, sexist, useless, or useful.  Nobody really stands up for it, except as an simple, objective measure of weight for height. Now, the AMA decided to caution doctors about the misuse of BMI as a surrogate for […]

Cheers for Diverse Thinking on Dietary Guidance

January 20, 2023 — USDA yesterday appointed 20 nationally recognized nutrition and public health experts to serve on the 2025 Dietary Guidelines Advisory Committee. We find good reason for cheers about these appointments – not just because these are some brilliant people – but also because we see them bringing diverse thinking on dietary guidance to this process. Diverse […]
