November 23, 2024 — The claim is both straightforward and absurd. “An additional hour’s walk could add 376.3 min of life expectancy.” This is a near perfect reduction of “Exercise Is Medicine” to absurdity. Yes exercise is an excellent tonic and the benefits of physical activity for health are well documented. As a metaphor, exercise is medicine is not […]
May 26, 2024 — Skimming the headlines, it would be easy to think that the combination of mobile phones and social media are responsible for quite a range of our current ills – including mental health and obesity. If you want to dig deeper, you can find a whole tome on the subject from Jonathan Haidt. He has woven […]
March 26, 2024 — Eight states have moved to provide nutritious meals at school for free to all students. A few simple reasons make it clear enough that this is a good idea. It reduces the stigma attached to receiving free school meals while improving food security for children from low-income families. Furthermore, nutrition quality goes up for all […]
November 26, 2023 — As an article of faith, we like to believe that healthy habits will lead us to a longer life. So of course, it makes sense to develop healthy habits for eating, enjoy an active life, and get enough good sleep every night. But putting a number on the benefit of those habits is not so […]
October 25, 2023 — It’s a popular cause. Red meat production is a problem for the climate.

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. […]

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.
