Here's What — and When — to Eat Before Working Out

Within 30 minutes of finishing an intense workout, eat a snack that is a mix of carbs and protein. This will help reduce muscle soreness, and, since your body's metabolic rate is higher after a workout, it will give it the fuel it needs to recover. Heidi's faves include chocolate milk or yogurt (throw in an energy bar if you're famished or had a really intense workout), or cottage cheese with a banana or pineapple. Here are even more ideas for low-calorie post-workout snacks.
