Calorie rich and full of protein, nuts are a great way to up your caloric intake. Having nut butter on your usual snacks can add protein and calories to all your main meal timings. Cashew butter on a sliced apple, peanut/cashew butter on your toast or on a bagel will all add to your protein intake. For bulking, nuts are a nigh-on unbeatable way to add calories, but in moderation.
