A quick vending machine snack can be a catch-22.  High-sugar options such as candy make your blood sugar levels spike, giving you a burst of energy, and then drop, making you feel even more drained. It's not a lost cause, though—you can make smart choices at the vending machine. Rather than grabbing the candy bar or full-fat potato chips, look for low-calorie and low-fat options that may contain fiber, whole grains, fruit, and protein.

Look for these 8 smart options:

1. Low-fat Granola Bar
2. Low-fat Popcorn
3. Sunflower Seeds
4. Low-sodium Peanuts
5. Fat-free Pretzels
6. Chocolate-covered Nuts (such as Peanut M&Ms)
7. Baked Potato Chips (such as Baked! Lays)
8. Fruit Bar (such as Fig Newtons)
