To lose weight you must eat fewer calories than you use, and because it is hard work to significantly increase calorie use, reducing intake is far more important. You should exercise for better health, but data suggests most of us are eating twice the calories we need.
The Half Hour Diet reduces calorie intake by inserting a brief pause—after a smaller meal than usual—to give your body’s natural signals time to work. Start by eating half a meal then make a small adjustment if you are still hungry after the pause. Once satiety replaces hunger, it takes less willpower to resist eating more.
