September 25, 2023 — “Morning workouts turbocharge the benefits of exercise,” says Psychology Today. A litany of headlines like this have been crossing our screen for weeks now. They are insistent. “The early bird gets the worm – and sees better workout results,” said People magazine. “This is the best time of day to work out if you want […]
April 22, 2023 — An “impassioned polemic” is headed our way from British media doctor Chris van Tulleken and it aims to have us excise ultra-processed from our dietary habits. No doubt about it, ultra-processed food wins the prize for today’s best food boogeyman, but how wise is this bit of food fear based on correlation without a cause. […]
April 18, 2023 — Consider these two competing headlines. In the Washington Post, Kate Cohen tells us “It’s time to cancel diet culture.” Then with a press release about new papers in Nature Medicine, researchers tell us “Most new Type 2 diabetes cases attributable to suboptimal diet.” It’s a fascinating mashup of causality, attribution, and diet culture. On one […]
April 13, 2023 — This news just rolled in from the department of DUH at JAMA Network Open. Unwanted weight loss in older persons is a cause for concern. Perhaps some people have sailed through life without seeing a loved one wither when they suffer a devastating illness. But for most of us, this is not a big news […]
March 17, 2023 — “Coffee could slash obesity,” says the New York Post. Now you might think that cynical folks at the Post just make this stuff up because it’s so obviously false. But in fact, they have help from PR by the BMJ, and they’re not alone. The BMJ managed to induce quite a few news outlets last […]
February 26, 2023 — Quietly and systematically, Tera Fazzino has been working with colleagues to define a concept of hyper-palatable foods that might explain the apparent effect of ultra-processed foods on body composition and thus, obesity. The latest chapter in this quest appeared recently in Nature Food. In short, a narrative is taking shape that we may have a […]
December 23, 2022 — Causality in the relationship between obesity and depression is mighty hard to discern in a rigorous way. For clinicians, it seems obvious that obesity creates a risk for depression. Likewise, the observation that depression in some patients can lead to obesity is easy to find. But understanding that causal relationship is a challenge. Mere association […]
December 9, 2022 — We have four levels in our home – three sets of stairs to climb. So this new study in Nature Medicine yesterday definitely has our attention. Digging into observational activity monitor data from the UK Biobank, Emmanuel Stamatakis and colleagues from all over the world found that short bursts of vigorous activity – like quickly […]
October 11, 2022 — The toughest question about obesity is also the simplest and most basic. Why do we have so much more of it now? In the spirit of H.L. Mencken, most people presume the answer is also simple. People are just eating too much, moving too little, and they should change their ways. Problem solved. But in […]
May 13, 2022 — What is going on here? Why is this happening? What is the cause? The struggle to discern causality bedevils anyone who is serious about understanding obesity and how to overcome it. But the line between cause and effect can be very blurry, and fuzzy thinking ensues. And thus, the progress toward reversing the relentless increase […]
