Avocados are packed with B vitamins (proven stress-relievers), as well as monounsaturated fats and fiber, both of which help keep you full, says Gans. She recommends whipping up some homemade guacamole (but sticking to the suggested two-tablespoon serving size) and eating it with black bean chips. Alternatively, you could also just take half the fruit, add a squeeze of lime on top, and eat it with a spoon. Since avocado's so creamy, it can actually satisfy ice cream cravings, says Gans.
