Here are some tricks to make you feel more full so you don't derail your progress:
Drink tons of water. When you feel as if you're starving, pour yourself a huge glass of water — it will help quell the urge to eat.
Sleep! Getting the right amount of shut-eye will help curb your appetite.
Examine your hunger. The next time you feel really hungry between meals, consider the last time you ate. If it was less than three to four hours earlier, your stomach isn't growling, and you're not weak or tired, it's likely that you're emotionally unsatisfied rather than genuinely physically hungry.
Don't panic. You can and will lose weight. Even if you're eating more than your calorie allowance, you can still lose — it just might take a little longer. Exercise is crucial. Working out harder and more often will help burn those extra calories you might take in if you have a bad day.
Do NOT beat yourself up! You can do this. One slip up is one slip up, and if this is to be a lifestyle change you can't expect to be perfect 100 percent of the time. Believe in yourself, and get back on the wagon tomorrow.
