Instead of the questionable ingredients and fillers that are often found on the back of many quick-grab snacks, Arenas recommends these raw, vegan protein winners that have a whopping 17 grams of plant-based protein. While she likes Shanti Bars as a whole, her go-to flavor is Recover. "It contains turmeric for anti-inflammatory properties, cardamom to aid in digestion, chia and hemp seeds to boost your calcium and omega-3 intake," she explains. This type of snack is ideal post-workout to help settle your stomach, while also encouraging your body to release tension, build muscle and continue the endorphin high.

If you have access to a fridge during the day -- say, at your office -- consider putting together a few protein shakes to take with you when you know you have back-to-back meetings. Easy to throw together and delicious to devour, Arenas says this two-ingredient snack provides greens, pre-and-probiotics and the dose of vitamins and minerals you need. To make this powerhouse 3pm savior, combine one scoop of protein powder (her favorite is Garden of Life Raw Meal in vanilla) with 1 cup of coconut water and ice. " Keep the powder in a small container and shake with liquid in a shaker bottle when hunger strikes," she says.

While your visions of hard-boiled eggs might date back to hunting for multi-colored ones in your backyard, or they're simply an accessory to your cobb salad, eggs are an ideal snack choice, according to Walsh. Why? Not only are they low in calories -- coming in just under 70 -- but they're packed with protein, too. She explains they can lower cardiovascular disease and promote eye health, all while making sure you don't snap at your friend over Google Hangouts because you're starving. If you don't want to deal with the whole peeling-the-shell thing, buy prepackaged, peeled eggs. Try adding a pinch of salt, or even hot sauce, to give your snack an extra punch of flavor.

For a snack that you can easily tote around in your purse or down in a rush before heading to yet another brainstorm, Tannenbaum suggests thinking ahead and packing a smart combo of fruit and nut butter. While apple, pear or peach slices are a no-brainer, she adds that dried figs can also be a nice compliment to two tablespoons of almond butter. "This snack provides you with heart-healthy fat, protein, fiber and lots of vitamin C and iron, depending on what fruit you are choosing," she explains.
