Yesterday, another report came out to suggest that the prevalence of obesity and overweight may have peaked in the American population – at a combined prevalence of 75%. This particular report comes from Epic Research, based on electronic health records for more than 100 million patients. Every time one of these reports emerges, headlines are […]

Breathtaking. That’s the only word we can find to describe the claims coming from a cost effectiveness study of calorie labeling on restaurant menus for preventing cancer deaths. Published yesterday in BMJ Open, this study is already generating headlines like this one: “Thanks to calorie-counting menus, fewer Americans are dying of obesity-related cancers” Making an […]

For decades, we’ve watched growth in the prevalence of obesity and the chronic diseases it causes. Health systems have profited from treating those downstream diseases. Without really thinking about it, public health policy and payers have conspired to deny care for the root cause of those diseases – obesity. Bias inspired some of this because […]

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 […]

For a very long time, a basic question about the rising rate of obesity has seemed to frustrate people. Why is it relentlessly rising? Some pundits seem to think people have become stupid, lazy, or undisciplined over the last several decades. “You think cake wasn’t delicious iu 1969?” quipped one self-appointed expert recently. Others are […]

According to a press release from the University of Sheffield, it sounds like the city of London pretty much has obesity prevention figured out. All they had to do is ban adverts for junk food from public transport. Voilà! With that simple act, says the press release, London has prevented nearly 100,000 cases of obesity, […]

While many researchers are having scholarly debates about their competing models for obesity, they focus primarily upon how food is doing it to us. Is it the excessive supply of hyper-palatable, ultra-processed food? Or is it all about carbs and insulin? But nowhere in these lovely models is there any focus on factors that go […]

All models are wrong, but some are useful. Quite a distinguished collection of obesity researchers are working hard to prove that these words of a great statistician – George Box – were precisely correct. One group, led by David Ludwig, suggests that their carbohydrate-insulin model (CIM) for obesity “better reflects knowledge on the biology of […]

The problem with doing things to prolong your life is that all the extra years come at the end, when you’re old. Bob Mankoff captured this fundamental quandary in a New Yorker cartoon years ago. But the problem of managing health and risks remains on our minds nonetheless. So a new study in JAMA Network […]

The list of ways we woulda, coulda, shoulda prevented obesity keeps growing. In PLOS Medicine this week, another study is spawning headlines about a really effective tool for preventing obesity. The claim is that banning ads for unhealthy food can do the trick. The headlines are promising. For example, PLOS issued  a press release that […]
