February 14, 2019 — Last year, the New England Journal of Medicine retracted and then published a revised analysis of the landmark PREDIMED study. With that action, it shook the world of nutrition science. Even now, there’s still a whole lot of shakin going on. What About 267 Secondary Publications? Just last week in the BMJ, Arnav Agarwal and John […]
February 13, 2019 — Our president just had his annual medical exam and that ritual is providing us an important reminder. Self-reports – especially about obesity, nutrition, and physical activity – are not very reliable. That’s because most people misremember or shade the truth. We’re all lighter, taller, eating healthier, and more active when we do the reporting ourselves. A Long […]
February 10, 2019 — Sometimes things are not what they seem. That’s a problem when something slips into scientific literature that’s not exactly true. We offer a prime example today. Here we have two papers where an RCT – a randomized controlled study – is not properly randomized. Apparently, the investigators, reviewers, and editors for these papers weren’t too fussy about […]
January 29, 2019 — In obesity research, we have a bit of a cluster fuss on our hands. It’s all about a type of randomized study where the randomization is between clusters. This randomization method is important because it’s very useful for obesity prevention studies. For example, you might have children in different schools or different classrooms participating in […]
January 25, 2019 — JAMA grabbed some headlines this week on a popular subject – cutting sugar consumption for kids. Fatty liver disease is a serious problem and the headlines point to a simple solution. “To fight fatty liver, avoid sugary foods and drinks,” said the New York Times. How did researchers prove that?

January 21, 2019 — New research published last week in Cell offers a glimpse of how a critical part of the brain gets wired for obesity very early in life.

December 21, 2018 — As we’ve noted, 2018 was a year of toxic misinformation. Scholars from the Rand Corporation warned us about Truth Decay, because misinformation is creeping into every corner of our lives. So let’s take a minute to review some of the biggest whoppers of 2018. One by one, maybe they seemed trivial. But add them all […]
December 18, 2018 — Two recent articles have us thinking about the harm that might come from hanging on to weak dietary advice. One is all about salt. The other is about dairy fat. But underneath it all is core problem. Some of the dietary advice taken as gospel is grounded in associations and suppositions. It never goes through […]
December 16, 2018 — GWAS is an acronym that’s hard to avoid if you read much about obesity research. It’s shorthand for genome-wide association studies. And for the last several months, some of the brightest people in obesity research have been debating the merits of hammering away at GWAS that focuses on BMI. Does GWAS research miss the mark […]
