Delicious for breakfast and perfect after a workout, eggs can be eaten in many different forms, all without affecting their nutritional qualities. Remember, you need to boost your protein and carbohydrates after a workout, and eggs have both. Each chicken egg is about 70 calories, but they contain more than 6g of protein each. They also offer a vitamin D boost, and you don’t have to eat them raw like many people suggest. Boil, poach, or scramble, an egg is a great source of protein that’s suitable for eating after all kinds of workouts.
