Water

• If you're hungry as bedtime nears, it may be the result of dehydration. Water deprivation can make your stomach feel like it's grumbling, tricking you into thinking it's time to eat something. Sip a tall glass of water in the evening. If you're still hungry after drinking a full glass of water, consider a light snack.
  
  

Healthy Snack

• If you choose a snack wisely, it can appease your appetite until you fall asleep. Snacking can be tricky, though. If you don't pay attention to what you snack on, you might exceed the right amount of daily calories. Eating snacks high in fiber or lean protein can give you the sense of being full, cutting out the need for excessive snacking before bedtime. Eat your snack slowly. This allows you to better understand when you're satisfied so you don't overeat.
  
  

Occupy Yourself

• Never use eating as a way to satisfy boredom. Avoid having an unnecessary meal close to bed by keeping yourself busy. Read a book or complete a puzzle. Perform tasks that require focus and thought so you have less time to think about preparing food. Stay out of the kitchen.
  
  

Flavor Substitute

• Brushing your teeth or chewing a piece of gum can go a long way to dissuade you from eating a late-night dinner. The flavor of the toothpaste or gum can help ease your cravings for something sweet or tangy. The aftertaste can discourage you from eating anything else as well. Having a minty aftertaste in your mouth can greatly distort the flavor of other foods, making eating them an unpleasant experience. You're also less likely to want to dirty your mouth after brushing.
