A science writer reflects on the way paradigms work:
I’ve been a science reporter for 40 years. I’ve wanted to assume that the experts I interview can be trusted to understand their subjects. Put simply, to get it right. But watching researchers in the field of obesity almost blindly follow a failed paradigm has led me to cross a line that few journalists ever do, to publicly embrace and promote a minority opinion that many in the obesity field think is quackery.
For nearly a century, obesity research has been predicated on the belief that the cause of the disorder “is an energy imbalance between calories consumed and calories expended,” to quote the World Health Organization. By this ubiquitous thinking, obesity is an energy balance disorder: People get fat because they take in more calories than they expend. They stay lean when they don’t.
This is the central dogma of obesity science…
People don’t get fat because they eat too much, consuming more calories than they expend, but because the carbohydrates in their diets — both the quantity of carbohydrates and their quality — establish a hormonal milieu that fosters the accumulation of excess fat.Gary Taubes, “How a ‘fatally, tragically flawed’ paradigm has derailed the science of obesity” at Stat News (September 13, 2021)

If he’s right, a popular paradigm it was dangerous to doubt will come under fire.
