Whether you’re an athlete, a gym enthusiast, or just starting your fitness journey, it’s important to pay attention to your diet. Many people on a mission to get fit or lose weight place the bulk of their energy on exercising. People may choose to focus on the physical aspect more as they are reluctant to give up their unhealthy eating habits. They may be under the impression that heavy exercise will negate their unhealthy meal choices. The foods you eat before and after exercise will influence your performance. Proper nutrition gives your body the fuel to power through a workout and provides the nutrients it requires to recover after your workout. When your body recovers quickly, you can exercise consistently, and when you exercise consistently, you are more likely to see results. Before cutting out everything you think is ‘bad,’ vowing never to eat a sugary treat again, a better option is to take a step back and adjust how you think about food. In most cases, adopting an all-or-nothing approach is likely to set you up for failure. When you deprive yourself of something you enjoy, you will probably crave it, and at some point, there’s a good chance you’ll give in to your cravings and binge. This not only sets you back physically, but mentally as well. Binge eating can leave you feeling bad about yourself and your choices. When working on a meal plan, a more positive approach is to focus on all the foods you can and should eat rather than the ones you should eat less of. It’s also helpful to keep macronutrients and micronutrients in mind. Macronutrients are protein, carbs, and fats. Micronutrients are vitamins and minerals. Both macronutrients and micronutrients are essential, but you need them in varying amounts. So, fitness does indeed begin in the kitchen!
The Importance of Pre- and Post-Workout Nutrition
Eating and exercise go together. Knowing when and what to eat can make a difference in your workouts. When and what you eat can be important to how you feel when you exercise. And it's important to think about what you eat when you exercise, whether you're doing a casual workout or training for a competition. Not fueling up before you work out is like driving a car on empty.
Macronutrients: The Building Blocks of Energy and Recovery
Macronutrients are protein, carbs, and fats. Besides keeping you full so that you’re less likely to snack unnecessarily and consume more calories than your body needs, protein has many other roles and benefits. A lot of people also rely on protein supplements to hit their protein macro. When it comes to choosing your protein powder, there are several options. Common protein powders include soy, whey, brown rice, hemp, egg, casein, and pea. Each type has its benefits, and since everyone is different and has different needs, what works for others may not work for you. Before buying your protein powder, it’s a good idea to learn about the different types. Carbs give the body the energy to function daily and get the most out of a workout. Simple carbohydrates are not healthy and should be eaten in moderation. Candy, baked goods, and sugary drinks are some examples of simple carbs. Fats are a source of energy and help the body to absorb essential nutrients. They also aid in cell growth and regeneration and protect the bones and joints.
Micronutrients: Vitamins and Minerals for Optimal Function
Micronutrients are vitamins and minerals. While you need them in lower quantities than macronutrients, they are just as important. An excellent way to include micronutrients in your diet is to have a wide range of foods in your meal plan. When shopping, especially for produce, select fruits and veggies in different colors, as they each contain different vitamins and minerals.
The Role of Fluids and Electrolytes
Fluids. Drink water, of course. If you want to add more flavor, try adding lemon, lime or cucumber slices to your water. Blend your water with 100% fruit juice, such as orange juice, which provides hydration and carbohydrates. Electrolytes. Replenish electrolytes through food sources such as fruits, leafy green vegetables, fatty fish, low-fat dairy products, nuts and seeds. These all provide the electrolytes and minerals your body needs. Although sports drinks, tablets and powders can help replenish electrolytes, be cautious. These products are often very high in sugar and caffeine. Water is generally the best way to replace lost fluids. But if you're exercising for more than 60 minutes, try a sports drink. Sports drinks can help keep your body's electrolyte balance.

Timing Your Meals: Pre-Workout, During, and Post-Workout
- If you exercise in the morning, get up early enough to finish breakfast at least one hour before your workout. Studies suggest that eating or drinking carbohydrates before exercise can help you do better during your workout. And the carbohydrates may allow you to work out for a longer time or at a higher intensity. If you plan to exercise within an hour after breakfast, eat a light meal. Or have a sports drink. And remember, if you usually have coffee in the morning, it's probably OK to have a cup before your workout.
- Be careful not to overdo it when it comes to how much you eat before exercise. Large meals. Small meals or snacks. Eating too much before you exercise can leave you feeling slow-moving.
- 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 if your workout lasts less than 60 minutes. You don’t need to eat during a workout that’s an hour or less. If your workout is longer than 60 minutes, it may help to have a carbohydrate-rich food or drink during the workout.
- Eat a meal that has both carbohydrates and protein in it within two hours of your workout if possible. Eating after you work out can help muscles recover and replace their glycogen stores. In the 30-60 minutes after your workout, your muscles can store carbohydrates and protein as energy and help in recovery. Think about having a snack if your meal is more than two hours away.
Food Choices for Optimal Fitness
- Carbohydrates: You burn a lot of carbohydrates - the main fuel for your muscles - when you exercise.
- Protein: Eat foods that are healthy sources of protein such, as skinless chicken breast, salmon, trout, lean or low-fat ground beef or pork. Some vegetarian healthy sources of protein include beans, peas, lentils, nuts and seeds.
- Healthy Fats: Consume foods that are high in unsaturated fats including avocado, fatty fish, such as tuna, salmon or sardines, or nuts. Use non-tropical vegetable oils, such as canola or sunflower oil, when cooking instead of solid fats such as butter, coconut butter or oil. Avoiding saturated fats and proteins, even healthy ones. Your stomach digests these types of fuels slower.
Practical Snack Ideas
Consider stocking your workout bag and refrigerator with some of these simple snacks:
- Bananas: Bananas are full of potassium and magnesium, which are important nutrients to get on a daily basis. Eating a banana can help replenish these minerals while providing natural sugars to fuel your workout. For added protein, enjoy your banana with a serving of peanut butter.
- Berries, grapes, and oranges: These fruits are all full of vitamins, minerals, and water. They’re easy on your intestines, give you a quick boost of energy, and help you stay hydrated. Consider pairing them with a serving of yogurt for protein.
- Nuts: Nuts are a great source of heart-healthy fats and also provide protein and essential nutrients. They can give you a source of sustained energy for your workout. Pair them with fresh or dried fruit for a healthy dose of carbohydrates. However, test these options to see how they settle. High-fat foods can slow digestion, and they may make food sit in your stomach too long if your workout is coming up quickly.
- Nut butter: Many grocery stores carry single-serving packets of peanut butter that don’t require refrigeration and can be easily stored in a gym bag. For a tasty protein-carbohydrate combo, you can spread peanut butter on: an apple, a banana, whole-grain crackers, or a slice of whole-grain bread. If you don’t like peanut butter, try almond butter, soy butter, or other protein-rich alternatives.
- Start With Whole-Grain Cereal: If you don’t have enough to eat before you exercise, you may not have enough gas in the tank. You might burn fewer calories, too. Have some healthy carbs at least an hour in advance of your workout. Try a bowl of whole-grain cereal with skim milk and cut up fruit or some whole wheat toast or a bagel. Cream cheese and butter add saturated fat.
- Grab a Banana: Don’t have much time before you head to the gym? Eat an apple or a banana 5 or 10 minutes before your workout for some quick, natural energy. Your body easily digests these carbohydrates and turns them into the energy you need for exercise. Also, fruit is packed with helpful nutrients.
- An Energy Bar in the Afternoon: When you’re working out later in the day, have a small snack about an hour before you get started. A sports bar that has 200 calories or less is a good option. Look for a bar with low-fiber content, ideally 3 grams or less. Too much fiber before a workout can upset your stomach. On the ingredients list, keep an eye out for sugar alcohols, like sorbitol, xylitol, isomalt, and mannitol. Too much of these ingredients can give you cramps or diarrhea.
- Grilled Chicken at Mealtime: When you exercise regularly, you need more protein than people who don’t, especially after a workout. Your body uses it to repair muscles, to make blood cells, and for many other purposes. For lunch or dinner, serve a leaner source, like grilled chicken or turkey, instead of something like a cheeseburger.
- Black Bean Burger: Whether you sometimes try a meat-free meal or stick to a full-time vegetarian diet, you can get plenty of protein (and lots of other nutrients, including fiber) from plants. Try pinto, kidney, white, or black beans, split peas, or chickpeas. Soy products, like tofu and tempeh, and nuts also have protein.
- A Bowl of Berries: After a workout, go for these instead of a bottle of juice. A lot of the fiber in whole fruits is lost as they become juice. Blueberries, in particular, have been shown to reduce muscle soreness from strenuous exercise. Cherries are another good option. But any berry will likely help.
- Veggies and Hummus: When you exercise regularly, it’s all too easy to overestimate how many calories you’ve burned. An intense, hour-long bike ride could burn 590 calories, but a more leisurely one might only use 290. While you might feel like you’ve earned a cookie, it’s better to snack on fruits and vegetables. After you work out, pair your produce with protein to help you feel more full and replenish muscles. Try vegetables with hummus or fruit with Greek yogurt.
- Peanut Butter: While you train for a big event, the ideal post-workout snack combines protein with carbs. Revisit your childhood with a sandwich made with 2 slices of bread and 4 tablespoons of peanut butter. Of course, now that you’re an adult, you can substitute almond butter. Or try two or three cooked eggs for protein with a half a bagel.
Don't Forget to Walk After Eating
Whether you’re hustling to a post-lunch meeting or can’t wait to watch your favorite show after dinner, it can be tempting to hurry to your next task right after a meal. But research suggests that it can be remarkably beneficial to carve out just a little time for a new hobby: walking after eating. The health benefits of walking are real, no matter what time of day you lace up. But a mounting body of scientific evidence hints that you might accrue even more benefits by timing some of those steps wisely. Research has found significant improvements in blood sugar and other so-called cardiometabolic risk factors when people took a walk instead of standing still or sitting after meals. While experts have mixed opinions on exactly how soon to walk after meals, they generally agree that it’s good to get moving as soon as you can - ideally within a half an hour of eating. It’s possible to benefit even from a brief, leisurely stroll. Health improvements have been seen even with walking at a slow pace for as little as two to five minutes. Taking a 15-minute walk after each meal may further improve your cardiometabolic health.
Benefits of Walking After Eating
- Helps Balance Blood Sugar:Walking after eating not only helps keep our blood sugar in check, but can even help lower it. Research shows that physical activity right after a meal, starting at a mere two to five minutes of walking, can have a beneficial impact on post-meal hyperglycemia (elevated blood glucose). Even standing up rather than sitting or lying down after a meal is enough to engage muscles and make the blood sugar hurdle more of a speed bump, science suggests.
- Promotes Smoother Digestion: Walking after eating has been shown to stimulate digestion. Walking after eating for 10-15 minutes has been shown to help adults who frequently experience bloating feel markedly less so after eating. What’s more, a post-meal stroll can help reduce forms of gastrointestinal (GI) distress, like gas.
- Eases Constipation: Another benefit to walking after eating is that it can boost gastrointestinal movement, which can help if you’ve been a little, er, blocked up. A number of studies have suggested that walking can both speed up your digestive system and make stool easier to pass.
- Increases Circulation: Walking after eating also helps improve circulation. This means that more blood is pumped to our muscles and brain-another reason why you might feel even more invigorated by walking after eating rather than working (or snoozing, scrolling, or sitting) after a meal.
- Boosts Mood: Being active post-meal-or really any time of the day-can be a mood booster. Physical activity can boost your circulating levels of ‘feel good’ hormones, including endorphins and dopamine. Walking also helps make your brain more sensitive to the neurotransmitter serotonin. With serotonin at normal levels, you will likely feel calmer, happier, and more even-keeled, and might find it easier to focus as well.
- Supports a Healthy Heart: Walking and movement benefit the heart. Regular walking has been shown to reduce a person’s risk of heart disease and stroke. Plus, it helps manage weight, cholesterol, and blood pressure.
- It’s an Easy Way to Fit In More Movement: One of the most compelling reasons to head out for a walk after eating is that this can be one of the simplest ways to squeeze in a little extra movement-or possibly any movement at all!-into your day.
How Long Should You Walk After Meals?
Any amount of movement post-meal will offer benefits ranging from blood sugar management, boosting mood, and supporting digestion. Starting at two minutes of walking, you’ll likely begin to accrue measurable blood sugar benefits by a post-meal stroll. The goal is at least 150 minutes of moderate aerobic activity a week, or about 30 minutes five days a week. There’s no “magic number” for how long or how fast to walk after eating for maximal benefits, since each individual is different, and age and mobility can make a difference.
General Guidelines
It’s important to realize that these are general guidelines. Do what works best for you. Let your experience guide you on which pre- and post-exercise eating habits work best for you. Know that what you put in your body (nutrition) is as important as what you do with your body (exercise).
