Do Something Just for Yourself

These pre-portioned packages usually contain little to no nutritional value, and people often eat more than one.

Instead, prepare your own 150 calorie snack by combining almonds and your favorite dried fruit for a good combination of healthy fats, protein, and carbs.

Try using a rewards system: Once you knock three items off your list, or once you finish a particularly grueling task, you can allow yourself to check Twitter, eat a snack, or go to the gym.

If you want to eat some snacks right now, consider if you're just thirsty. It is not uncommon to confuse hunger with thirst.

Reach for a glass of water or a can of seltzer before grabbing a snack. You may discover that you were not really hungry.
