4. Load up on water-based foods. Eating foods with high water content will keep you hydrated and help you cut back on the calories. Water-based foods such as lettuce, fresh vegetables and some fruits also provide a high dose of vitamins and minerals.

5. Eat more fiber. In addition to eating water-based foods, increasing your fiber intake can help eliminate toxins in your body and improve your digestive system. This is important for keeping your metabolism running in high gear, and the fiber will help regulate your appetite. Look for filling foods like whole-wheat pasta, popcorn and fruits like raspberries and apples (skin on).
