Science journalist/historian Gary Taubes (author of Good Calories, Bad Calories and Why We Get Fat) has a highly-readable guest column in Slate today: "
It's Not About the Calories: Why existing efforts to combat childhood obesity are bound to fail."
He discusses how positive, well-intentioned programs like "Let's Move!" cannot succeed unless they give up the mistaken conventional wisdom of sheer "calories in, calories out" and embrace the scientific evidence of how the human body really regulates fat accumulation (hormones in relation to macronutrients).
