The collective wisdom from this poll is that expending more energy than we consume will lead to long-term weight loss.
This is contrary to what Gary Taubes wrote in his book, Good Calories, Bad Calories: Challenging the Conventional Wisdom on Diet, Weight Control, and Disease.
"Obesity is a disorder of excess fat accumulation, not overeating, and not sedentary behavior."
"Consuming excess calories does not cause [Taubes' emphasis] us to grow fatter, any more than it causes a child to grow taller. Expending more energy than we consume does not lead to long-term weight loss; it leads to hunger."
