When you're trying to watch what you eat, you probably walk to the refrigerator and stand there for five minutes, waiting for the perfect snack to appear. When you don't see something you like, you're more tempted to grab something unhealthy from the pantry (hello, potato chips). To combat bad cravings, purchase healthy foods like fresh fruits, vegetables and nonfat dairy products. Wash the fruits and veggies so they're ready to go. Place these foods on the shelf you know you'll look at the minute you open the refrigerator. Now, when you start staring longingly at the fridge, you'll see healthy and tasty options that are ready for immediate snacking.
