Rick Warren: What do faith, friends and fitness have to do with losing weight?
Friends, fitness ... and faith!
“Calories are a form of energy, and according to the laws of physics, a calorie is a calorie—the amount of energy required to raise the temperature of one liter of water by one degree centigrade,” writes Warren. “This law is true for physics, but all bets are off when you put biology in the mix. If it was all about ‘eat less, exercise more,’ we would all do it and be skinny and fit. But there are different kinds of calories: healing calories and disease-causing calories."
