What really works
So what makes a good pre-workout snack? Bonci likes to aim for a mix of carbs, protein, and a touch of healthy fats—all of it 200 calories or less. Some of her go-tos include a six-inch tortilla thinly spread with dark chocolate, peanut butter, and half of a sliced banana; she also likes a smoothie made with half a cup of fruit, soy milk, yogurt, and a smear of nut butter. "Liquids like smoothies leave the stomach more quickly, which means they get energy to the rest of your body faster." Regardless of what sounds most delicious and nutritious to you, just make sure you eat something before you exercise. "Even if you're trying to lose weight, exercising on an empty stomach is not as efficient because you can't work out up to your potential," Bonci says. Plus, you're likely to be hungrier as a result and overdo it at your next meal.
