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 […]

Embracing the basic truth that one size does not fit all, January is no longer “diet season” for all. Sure, you can find folks promoting everything from healthy dietary patterns like the Mediterranean diet to diets aimed more directly at weight loss, like intermittent fasting. But now, non-diet diets are sharing the spotlight, too. Intuitive […]

The food policy spin machine was in overdrive a few years ago, promoting food labeling policies enacted in Chile. “Latin America’s war on obesity could be a model for U.S.,” gushed the Washington Post.

“Let’s just agree to disagree” is an expression of utter nonsense, says Professor David Allison in an introduction to the concept of adversarial collaboration. Of course, he is describing this in the context of scientific controversies. And in obesity and nutrition research, it’s quite easy to construct a list of subjects on which the disagreements […]

We live in an age of algorithms and machine learning, says Professor Barbara Fister. But we should be aware that a bigot can find its way into the machine. She explains: “A provider of healthcare decision-making software that helps to manage care for some 200 million people each year wanted to create an algorithm to […]

You can’t outrun a bad diet. It’s a clever turn of phrase that resonates. But like many things that resonate about diet, exercise, and obesity, it might be a little too clever.

Step right up and hear all about an amazing vegan diet study. The Physicians Committee for Responsible Medicine (PCRM) churned out quite a PR masterpiece of hype recently.
