Maybe the simple advice of “Eat less, move more,” nice as it sounds, is too simple, and frankly, wrong. The most widely accepted and promulgated advice of the last fifty years is under attack: Maybe a calorie is not a calorie. It would be a long time before we started to pull the threads together and come up with coherent explanations of why we do what we do.Ī similar pattern emerges as we survey the field of nutrition today.
They couldn’t be falsified, and they claimed to explain too much, even patently opposite behaviors. Most were unscientific, in the Popperian sense. There were theories of mind, theories of self, theories of everything, but nearly all of them were incomplete and contradictory explanations of human behavior. (That didn’t happen until the modern synthesis in the 1940s.) Nutrition, as a scientific field, is reminiscent of psychology in its infancy - before Skinner’s or Pavlov’s ideas had made a dent, before there was Piaget, Kahneman, Tversky, Munger before we had a field called “ evolutionary psychology.” Heck, before biology itself had really come to grips with Darwin’s ideas about evolution through natural selection. Let’s examine the truth about what causes weight gain – and what we can learn about biases from the field of nutritional science. It’s time to turn the food pyramid upside down. We’ve been told for decades that dietary fat makes us gain weight, yet research suggests refined carbohydrates are to blame.
