"Between client appointments and my own workouts, I'm always on the go. That's why I'm such a big fan of single serve tuna pouches. Starkist makes a version that's 2.6 ounces and has 17 grams of protein, which is great to eat after a workout. It's a healthy, clean option that's easy to eat anywhere." —Ajia Cherry, personal trainer and Founder at Functional Innovative Training

"Tuna is a perfect food for those of us who want to bulk up our bodies without leaning out our wallets. One 3 ounce can of this budget-friendly delicacy contains 16 grams of protein and costs about $1.25. Though it's one of my favorite foods, I'm sure to limit myself to one can per week due to the mercury content." — Jay Cardiello, the fitness and nutrition expert behind 50 Cent and J.Lo's killer physiques

"Nut butter is all the rage right now — and it's well deserved attention. Almond butter is full of healthy fats and natural proteins and it pairs nicely with an apple. Apples are an underrated low-calorie superfood and the sweet and salty combination of both together can't be beat." — Dan Roberts, author of the fashion model workout, Methodology X

"I always have hard boiled eggs in my fridge. They are filled with protein and fat-burning nutrients like choline which is found in the yolk. Since I'm usually short on time, I'll grab two right after a workout for a quick snack." — Kit Rich, celebrity trainer and co-owner of SHIFT by Dana Perri

"Though there are more nutrient dense seeds on supermarket shelves I love these little things. Sometimes you just have to go with what you like in terms of taste, before considering macronutrients. Cashews are a primo source of protein and healthy fats, and they also contain some energy-fueling carbohydrates, which is probably why they taste so good!" —Roberts

"I like to add a scoop of protein powder (I'm a big fan of Apex) into low-fat Greek yogurt with some nuts or berries on top. It's a tasty, nutrient-rich snack that only takes a few minutes to make. The trick, so that it doesn't clump, is to mix the powder in a little water before adding to the yogurt." — Andrew Dottermusch, Senior Director of Retail, 24 Hour Fitness

"Not only do pumpkin seeds have a tasty flavor and satisfying crunch, a 1/2 a cup supplies a whopping 14 grams of protein and a great deal of magnesium. Throw the seeds into a shake to boost satiety and nutrition, or simply enjoy them plain. Either way, they're delicious." —Cardiello

"For a quick hit of post-workout protein, I'll blend a single-serving, non-fat plain Greek yogurt with plain almond milk, a banana and 2 tablespoons of natural peanut butter. Be sure to chose a low-sugar brand free of heart-harming hydrogenated oils and trans fats." — Jim White RD, ACSM HFS, Owner of Jim White Fitness and Nutrition Studios
