Eating and Exercise
by: Mayo Clinic 

Eating and exercise go hand in hand. When and what you eat can be important to how you feel when you exercise, whether it's a casual workout or training for a competition. Consider these eating and exercise tips.

If you exercise in the morning, get up early enough to finish breakfast at least one hour before your workout. Most of the energy you got from dinner the previous night is used up by morning, and your blood sugar might be low. If you don't eat, you might feel sluggish or lightheaded when you exercise.

If you plan to exercise within an hour after breakfast, eat a light breakfast or drink something to raise your blood sugar, such as a sports drink. Emphasize carbohydrates for maximum energy.

Good breakfast options include:

• Whole-grain cereals or bread
• Low-fat milk
• Juice
• Bananas
• Yogurt
• A waffle or pancake

And remember, if you normally have coffee in the mornings, a cup before your workout is probably OK. Also know that anytime you try a food or drink for the first time before a workout, you risk an upset stomach.

Be careful not to overdo it when it comes to how much you eat before exercise. The general guideline:

• Large meals. Eat these at least three to four hours before exercising.
• Small meals. Eat these two to three hours before exercising.
• Small snacks. Eat these an hour before exercising.

Eating too much before you exercise can leave you feeling sluggish. Eating too little might not give you the energy to keep you feeling strong throughout your workout.

Most people can eat small snacks right before and during exercise. The key is how you feel. Do what works best for you. Snacks eaten soon before exercise probably won't give you added energy, but they can help keep up your blood sugar and prevent distracting hunger pangs. Good snack options include:

• Energy bars
• Bananas or other fresh fruit
• Yogurt
• Fruit smoothies
• Whole-grain bagel or crackers
• Low-fat granola bars
• Peanut butter sandwiches

A healthy snack is especially important if you plan a workout several hours after a meal.

To help your muscles recover and to replace their glycogen stores, eat a meal that contains both protein and carbohydrates within two hours of your exercise session if possible. Good post-workout food choices include:

• Yogurt and fruit
• Peanut butter sandwich
• Low-fat chocolate milk and pretzels
• Pasta with meatballs
• Chicken with brown rice

Don't forget to drink fluids. You need adequate fluids before, during and after exercise to help prevent dehydration.

To stay well-hydrated for exercise, the American College of Sports Medicine recommends that you:

• Drink roughly 2 to 3 cups (473 to 710 milliliters) of water during the two to three hours before your workout.
• Drink about 1/2 to 1 cup (118 to 237 milliliters) of water every 15 to 20 minutes during your workout. Adjust amounts related to your body size and the weather.
• Drink roughly 2 to 3 cups (473 to 710 milliliters) of water after your workout for every pound (0.5 kilogram) of weight you lose during the workout.

Water is generally the best way to replace lost fluids. But if you're exercising for more than 60 minutes, use a sports drink. Sports drinks can help maintain your body's electrolyte balance and give you a bit more energy because they contain carbohydrates.

Keep in mind that the duration and intensity of your activity will dictate how often and what you should eat and drink. For example, you'll need more energy from food to run a marathon than to walk around the block.

When it comes to eating and exercise, everyone is different. So pay attention to how you feel during your workout and to your overall performance. Let your experience guide you on which pre- and post-exercise eating habits work best for you. Consider keeping a journal to monitor how your body reacts to meals and snacks so that you can tweak your diet for optimal performance.
