Cut your caloric intake by 10 percent. One of the largest bodies of research in the study of nutrition clearly identifies that mildly cutting back on the calories you take in is one of the greatest techniques to ward off disease and prolong your life. This is not to suggest that you should go on a fad diet that advocates strict caloric limitations (so, no 600 calories per day madness). However, by making the right small choices, you can eat until you are sufficiently sufficed, not stuffed! Start implementing this simple tip by leaving a little bit of food behind on your plate at each meal, trimming down your protein size by an ounce or so, or by eating one piece instead of two (try an open-face sandwich at lunch). You’ll soon realize your body doesn’t need as much food as you were giving it.
