Eating sensibly can actually keep you physically and emotionally satisfied. In order to curb your appetite, begin each meal with a green salad. This will keep you away from overloading on the main course. In a study of 42 women, those who started their pasta lunch with a 100 calorie salad containing 3 1/2 cups of greens, ate far fewer calories over the course of the meal than those not served a salad.
