What Explains Racial and Ethnic Disparities in Obesity?

January 8, 2020 — What could it be that explains racial and ethnic disparities in obesity? The most common thought is that it’s all about differences in health behaviors, along with social and economic status. The thinking is that poverty and educational disadvantages make it hard to eat healthy and stay fit. But a new study in Obesity tells […]

Obesity, Despair, and Mortality in the U.S.

November 27, 2019 — We’ve only just begun. That was once a hopeful refrain. But now, it applies to a worrisome trend. Working age people in the U.S. are dying at rates that are unprecedented among wealthy countries. This finding comes from a stunning, comprehensive study of a reversal in U.S. life expectancy.

Can Happy Rats Tell Us Something About Obesity?

October 20, 2019 — All around us, we read mostly collegial (sometimes acrimonious) debates about how to do obesity and nutrition research right. Are randomized, controlled studies the best way to get definitive answers? What about nutritional epidemiology? Or animal studies? Some of these debates about methods and inferences are raucous. For a note of caution, we offer a […]

The Urban-Rural Race to Obesity

May 9, 2019 — “There’s a heck of a lot of bias among a lot of researchers,” Professor Barry Popkin tells us. On the subject of what’s driving global obesity prevalence, he’s certainly right.

Obesity-Related Cancer Rising in Millennials

February 5, 2019 — Most often, when public health reports discuss the impact of rising obesity, the focus is on diabetes and its complications. Cancer does not spring to mind.

Getting a Handle on the Social Environment for Obesity

November 30, 2018 — The idea that obesity is contagious is a “brilliant analogy,” says a distinguished professor of pediatrics, Leonard Epstein. More and more research supports this view. But the ideas about contagion require careful thinking in this context. Thinking about transmitting obesity from one person to another is not especially helpful. What’s more relevant is thinking about […]

Self Reports of Virtue in Nutrition

November 4, 2018 — In an editorial for JAMA this week, Frank Hu and Walter Willett tell us they have a clear view of the future for nutrition research. We’ve broken the bonds of biochemistry, animal models, and feeding studies. Biomarkers are nice, but at best they can only complement – not replace – dietary self reports. Thanks to […]

A Gut Instinct for Finding Childhood Obesity

October 26, 2018 — At the age of 2, it’s not especially obvious if a child will have obesity later in life. But a new study, published in mBio, suggests that the microbes in a child’s gut at age 2 might offer some pretty good clues. Microbiota Explaining More Than Half of BMI Scores Maggie Stanislawski and colleagues analyzed data […]

Looking for Clues in Remissions of Childhood Obesity

August 7, 2018 — Childhood obesity generates a lot of talk. But it might surprise you to learn how little we actually know about the natural history of this disease. And what little we know has been a bit discouraging. However, a new study by Danny Luan and colleagues offers some important new insight. Remissions, Though Not Typical, Are […]

A Study to Change the Way We Think About Obesity?

July 16, 2018 — Researchers at York are telling us they have a breakthrough that will change the way we think about obesity. At least that’s what their press release says. And it worked. They made us click the link. Jennifer Kuk and colleagues found that about one in 20 (5%) of people with a BMI over 30 have […]
