If you like a side of crunch with your snacks, Paula Simpson, holistic nutritionist and co-founder of Zea Skin Solutions says popcorn isn't at all a bad choice for a quick snack, especially if you add some spice to the kernels. "Popcorn with paprika and sea salt makes a great mid-afternoon snack when energy levels are down and cravings are up," she says. "Paprika contains carotenoid antioxidant zeaxanthin, an important antioxidant that has been clinically shown to support eye and skin health."

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.
