It's easy when you have a high-stress life and are constantly on the move to eat the quickest thing available to you. However, those unhealthy cravings aren't the only easy options. Here are six healthy substitutions when you have a craving for a snack that you may regret later.

1. Protein shakes instead of milkshakes:

Ingredients:
- 1 scoop whey chocolate protein powder
- 1 banana
- 1 tablespoon almond butter
- 1 cup almond milk/water/low fat milk
- Hand full of ice

Throw it in the blender and there you go; a healthy alternative to a milkshake.

2. Almond butter and strawberrieson rice cakesinstead of PB & J

Who doesn't love a good ol' PB & J sandwich? Replace white bread with rice cakes and that knocks off 100+ calories and a good amount of carbs. To get even better, substitute jelly with berries to get away from all that added sugar.

3. Greek Yogurt instead of ice cream

How to make: Pick your favorite flavor of greek yogurt — if you want to be extra healthy, choose plain. Then add some cinnamon, fruit, seeds, nuts, low fat peanut butter or even a few chocolate chips.

4. Kale Chips instead of potato chips

How to make: Season kale with oil, salt, pepper and garlic. Put in 275 degree oven. Bake for 20 minutes or until crisp.

5. Frozen Fruit instead of candy

If you are craving something sweet or sour with a little crunch, try freezing your favorite fruit. Freezing fruit brings out a little different flavor and adds that extra kick that you're looking for. My personal favorite is frozen grapes; they taste like candy and are extremely refreshing.

6. Zucchini Spaghetti instead of pasta

Pasta is one of my favorite foods, but sometimes when I'm eating it, all I can think about are the amount of carbs. Problem solved with zucchini spaghetti. All you have to do is use a Veggetti maker — if you don't know what that is, here is the website where you can buy one and create spaghetti out of zucchini. Throw it in the microwave to warm it up, grate some cheese on there and you have a healthy version of pasta that tastes nearly identical.
