Gary Taubes : Calories vs Carbohydrates

Gary Taubes Calories vs Carbohydrates: Clearing up Confusion over Competing Obesity Paradigms

The science of obesity has been dogged for a century by a controversial question: is the condition an energy balance problem or a hormonal one? Do we accumulate excess fat merely because we consume more calories than we expend — we eat too much and exercise too little — or do we accumulate excess fat because the homeostatic mechanisms regulating fat metabolism and storage are out of whack. If the latter is the case, then positive energy balance (overeating) is an effect of getting fat, not a cause, and the prime environmental suspect for the cause of excess adiposity is the carbohydrate content of the diet and its effect on insulin signaling. This video by author Gary Taubes covers how we might tell these two scenarios apart and potential experiments to resolve this century-old conflict.

“I’m convinced that understanding our evolutionary journey is going to play a role in our future, our future survival as well as the survival of all creatures on this planet,” he said. “We know we have a united past, we know that we are the same species, we know we have inherited the same capabilities. And I think hopefully this is going to lead to a world in which we’re more responsible to the natural world — the natural world that ultimately was our creator on this planet. …

“I think it’s time for this species, the most powerful, the most destructive and at the same time the most creative species on planet Earth — Homo sapiens — to stop acting as if there was some other place for us to move to.”
