Most people don't spread their nutrition evenly through the day. Some prefer a large breakfast, a very light lunch, and a moderate dinner, while others skip breakfast entirely, eat a substantial meal in the middle of the day, and have a light supper in the evening. If you're happy with your present pattern of meals, stick with it. You may discover, once you start to cut back on food, that you consistently feel hungry at a specific time of day, in the late afternoon, for example. If that occurs, try shifting the balance among meals--moving, perhaps, some calories from dinner to lunch to spread your calories more evenly.
