Are Social Factors Driving the Growth in Obesity?

June 21, 2022 — 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 […]

Obesity: My Model’s Better Than Your Model

June 19, 2022 — 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 […]

Managing Risks, Gaining Life in Type 2 Diabetes

April 19, 2022 — 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 headlines are promising. For example, PLOS issued  a press release that […]

Model Assumptions for Driving Health Policy

April 22, 2020 — “I was never involved in a model. At least this kind of a model,” said our President at a recent press briefing. But now it seems that all of us are getting a crash course in modeling and model assumptions for making health policy. Perhaps we will learn to think more critically about the output […]

Sugar: Solve for the Answer You Like

September 29, 2019 — The assumption that too much sugar explains our problem with obesity has become ambient white noise. Most people just accept it. Inconvenient facts fade into oblivion. Modelers grab the megaphone claiming to have evidence that sugar is the cause and the key for overcoming obesity. It’s easy enough to solve for the answer you like […]

Obesity Solution: Don’t Let Them Eat Cake

September 8, 2019 — “The evidence is stacking up,” say Susan Jebb and Theresa Marteau. Sugary drink taxes have been so successful in the UK that the time has come to move on and tax chocolates, biscuits, and cake. And they have a modeling study to prove it. In just one year, a 20 percent tax on sugary snacks […]

Peer Reviewed Speculation About Labeling Added Sugars

June 3, 2019 — Disclosing how much added sugar is in a food product is a good idea. Claiming it “will save millions of lives and billions of dollars” is not. Wandering away from the truth never is. But in Circulation last month, Yue Huang et al are bold to say they only have one worry about the precision […]
