Skipping meals frightens your body into thinking you are going to starve. Try to eat every 3 or 4 hours, alternating between meals and snacks. Set an alarm to help you remember. Include sources of fiber, healthy fats and protein whenever you can. Fiber makes you feel full without piling extra calories into your belly. Complex carbohydrates like brown rice and whole wheat bread also help you feel satisfied longer. The best tool for success? Plan your meals and snacks ahead of time to stay consistent.
