What to Eat Before and After Exercise

Before exercise, eat something with easy-to-digest carbohydrates and a little protein, timed so your stomach feels comfortable: a full meal three to four hours ahead, or a light snack one hour before. Afterward, have a meal or snack with both carbohydrates and protein within a couple of hours, and drink fluids to replace what you sweated out. For a brisk walk or a short workout, your normal meals are usually enough.

Do you need a special plan?

It depends on what you’re doing. A 30-minute walk, a yoga class or an easy bike ride rarely needs special fueling; regular, balanced meals cover it. Timing starts to matter more when sessions are long (more than about an hour), intense, or back-to-back, or when you exercise first thing in the morning or right after work when your last meal was hours ago.

The goals are simple. Before: have enough energy without an upset stomach. After: refill energy stores, give muscles protein to repair, and rehydrate.

Before: match the food to the timing

The closer you are to exercise, the smaller and simpler the food should be. Fat, fiber and large portions take longer to digest and can cause cramping or sluggishness during hard effort.

Time before exercise	What to aim for	Examples
3–4 hours	A regular balanced meal with carbs, protein, some fat and fiber	Chicken, rice and vegetables; whole-wheat pasta with turkey meat sauce; a bean burrito
1–2 hours	A smaller meal or snack, mostly carbs with a little protein	Oatmeal made with milk; yogurt with fruit; half a turkey sandwich
Under 1 hour	A small, easy-to-digest carbohydrate	A banana; a handful of crackers; applesauce; a small glass of juice
Early morning	Whatever sits well, even something small	Half a banana or a slice of toast with honey

Try new foods on training days, not on the morning of a race or big game. Everyone’s stomach is different, and you’ll learn what works for you.

During: only for longer sessions

For most workouts under an hour, water is all you need. For continuous endurance activity lasting longer than an hour, such as a long run, ride or hike, many people benefit from some carbohydrate along the way: a sports drink, a banana, a few dried fruits or a small sandwich. Heavy sweaters exercising in heat may also need to replace sodium, which sports drinks and salty snacks provide.

After: refuel and repair

Muscles use stored carbohydrate (glycogen) for fuel and need protein to rebuild after work. A post-exercise meal or snack that includes both covers each job. Approximate protein values from USDA FoodData Central:

• Low-fat chocolate milk, 1 cup: about 8 g protein, plus carbohydrate
• Plain Greek yogurt, 6 oz, with fruit and a little granola: about 18–20 g protein
• Turkey sandwich on whole-grain bread with vegetables: about 20 g protein
• Two eggs with whole-grain toast and fruit: about 16 g protein
• Rice and black beans with salsa (1 cup beans, 1/2 cup rice): about 17 g protein
• Smoothie with 1 cup milk, a banana and 2 tbsp peanut butter: about 16–17 g protein

Within a couple of hours is a reasonable target. If you finish a workout and dinner is an hour away, dinner is your recovery meal.

Fluids: before, during and after

Thirst is a reasonable guide for most people. MedlinePlus lists dark yellow urine among the signs of dehydration, while pale yellow usually means you’re drinking enough. A few practical habits:

• Drink water through the day, not just at the gym.
• Sip during longer workouts, especially in heat.
• Afterward, drink water and include fluid-rich foods such as fruit, soup or milk.

Plain water is the best choice for everyday exercise. Sports drinks are designed for longer, sweatier sessions and add sugar you don’t need for a short workout.

Special situations

• Diabetes. Exercise affects blood sugar, and insulin or certain medications can make lows more likely. Ask your doctor or a diabetes care team how to plan food around activity.
• Teens and young athletes. Growing bodies need plenty of energy. Skipping meals before practice is a common reason for fatigue; a pediatrician or sports dietitian can help with individual needs.
• Weight goals. You don’t have to “earn” or “burn off” food. Eating enough around workouts supports the energy to keep exercising.
• Steady energy all day. What you eat across the day matters as much as the pre-workout snack. See our guide to foods for steady energy, and our article on what makes a healthy snack for portable ideas.

Putting it together

For everyday workouts, regular meals and water are plenty. For longer or harder sessions, eat a balanced meal a few hours ahead or a small carb snack closer in, add carbs during efforts past an hour, and follow up with carbs plus protein and fluids afterward. Experiment on regular training days and keep what makes you feel strong.
