Eating foods containing carbs and protein may help support your muscles after exercise. Experts recommend eating shortly after your workout for the most benefit.
When planning a workout, there’s a lot that goes into it to help you reach your goals.
As part of that effort, there’s a good chance you put a lot of thought into your pre-workout meal. But are you giving your post-workout meal the same attention? If not, it’s a good idea to do so. Consuming the right nutrients after exercise is just as important as eating before.
To help you optimize your nutrition after workouts, here is a detailed guide.
Eating after a workout is important
To understand how the right foods can help you after exercise, it’s important to learn how physical activity affects your body.
When you’re working out, your muscles use up their glycogen — the body’s preferred fuel source, especially during high intensity workouts. This results in your muscles being partially depleted of glycogen. Some of the proteins in your muscles can also be broken down and damaged.
After your workout, your body rebuilds glycogen stores and regrows those muscle proteins. Eating the right nutrients soon after you exercise can help your body get this done faster. It’s especially important to eat carbs and protein after your workout.
Doing this helps your body:
decrease muscle protein breakdown
increase muscle protein synthesis (growth)
restore glycogen stores
enhance recovery
Protein, carbs, and fat
Each macronutrient — protein, carbs, and fat — is involved in your body’s post-workout recovery process. That’s why it’s important to have the right mix.
The timing of your meals is also important. Sports nutrition researchers have been studying nutrient timing for more than 40 years. These days, experts rely on a mix of older and newer studies to make recommendations (1).
Protein helps repair and build muscle
Exercise triggers the breakdown of muscle protein. The rate at which this happens depends on the exercise and your level of training, but even well-trained athletes experience muscle-protein breakdown (1, 2Trusted Source, 3Trusted Source, 4Trusted Source, 5Trusted Source, 6Trusted Source).
Consuming an adequate amount of protein throughout the day gives your body the amino acids it needs to repair and rebuild these proteins. It also gives you the building blocks required to build new muscle tissue (1, 7Trusted Source, 8Trusted Source, 9Trusted Source, 10Trusted Source).
It’s recommended to split up your protein intake across the entire day, at 3-hour intervals. So you’ll want to eat protein as part of small meals spaced throughout the day. Depending on your body weight, 20-40 grams of protein every 3 to 4 hours is recommended (1).
Studies have shown that ingesting 20–40 grams of protein seems to maximize the body’s ability to recover after exercise (9Trusted Source, 11Trusted Source).
In addition, eating protein before exercise may decrease the amount you need to eat after without affecting recovery (1).
One study found that eating protein pre-workout and post-workout has a similar effect on muscle strength, hypertrophy, and body composition changes (12Trusted Source).
But if you’re specifically aiming to build muscle, eating high quality protein within the first 2 hours after a workout may stimulate your body to create the building blocks for new muscle tissue (1).
Carbs help with recovery
Your body’s glycogen stores are used as fuel during exercise, and consuming carbs after your workout helps replenish them.
The rate at which your glycogen stores are used depends on the activity. For example, endurance sports cause your body to use more glycogen than resistance training. For this reason, if you participate in endurance sports (running, swimming, etc.), you might need to consume more carbs than someone engaging in weightlifting.
Eating a high carb diet of 3.6-5.5 grams of carbs per pound (8-12 grams per kilogram [kg]) of body weight each day can help you maximize your glycogen stores (1).
Furthermore, insulin secretion, which promotes glycogen synthesis, is better stimulated when carbs and protein are consumed at the same time (10Trusted Source, 11Trusted Source, 12Trusted Source, 13Trusted Source).
Therefore, consuming carbs and protein after exercise can maximize protein and glycogen synthesis (13Trusted Source, 14Trusted Source).
Early studies found benefits from consuming the two in a ratio of 3 to 1 (carbs to protein). For example, that’s 40 grams of protein and 120 grams of carbs (15Trusted Source, 16Trusted Source).
When rapid recovery is necessary (under 4 hours), current recommendations suggest a similar ratio. Specifically, you can help restore glycogen faster by consuming 0.4 grams of carbs per pound of body weight (0.8 grams of carbs per kg) with 0.1-0.2 grams of protein per pound of body weight (0.2-0.4 grams of protein per kg) during each hour of recovery (1).
Recommendations for carb intake are targeted to the needs of endurance athletes. If you’re focused on resistance training, you may need less.
What’s more, most studies on this topic involve only male athletes, so it’s unclear whether female athletes may have different intake needs.
Fat may provide some benefits
There is not enough evidence to say whether you should limit fat intake after a workout (1).
Many people think that eating fat after a workout slows digestion and inhibits the absorption of nutrients. While fat might slow down the absorption of your post-workout meal, it may not reduce its benefits. For example, a study showed that whole milk was more effective at promoting muscle growth after a workout than skim milk (17Trusted Source).
Moreover, another study showed that muscle glycogen synthesis was not affected even when ingesting a high fat meal (45% energy from fat) after working out (18Trusted Source).
Having some fat in your post-workout meal may not affect your recovery. But more studies are needed on this topic.
The timing of your post-workout meal matters
Your body’s ability to rebuild glycogen and protein is enhanced after you exercise (19Trusted Source).
For this reason, it’s recommended that you consume a combination of carbs and protein as soon as possible after exercising. In the past, experts recommended eating your post-workout meal within 45 minutes, as a delay of carb consumption by as little as 2 hours after a workout may lead to as much as 50% lower rates of glycogen synthesis (19Trusted Source, 20Trusted Source).
However, more recent research has found that the post-exercise window to maximize the muscular response to eating protein is wider than initially thought, up to as many as several hours (11Trusted Source).
Also, if you consumed a meal rich in whole carbs and protein perhaps an hour before exercising, it’s likely that the benefits from that meal still apply after training (21Trusted Source, 22Trusted Source, 23Trusted Source).
Also, recovery is not just about what you consume directly after working out. When you exercise consistently, the process is ongoing. It is best to continue to eat small, well-balanced meals of carbs and protein every 3–4 hours (24Trusted Source).
Foods to eat after you work out
The primary goal of your post-workout meal is to supply your body with the right nutrients for adequate recovery and maximize your workout’s benefits. Choosing easily digested foods will promote faster nutrient absorption.
The following lists contain examples of simple and easily digested foods:
Carbs
chocolate milk
quinoa and other grains
fruits (such as pineapple, berries, banana, kiwi)
rice cakes
rice
potatoes
pasta
whole grain bread
Protein
animal- or plant-based protein powder
eggs
Greek yogurt
cottage cheese
salmon
chicken
tuna
Fats
nuts
nut butters
seeds
trail mix (dried fruits and nuts)
Sample post-workout meals and snacks
Combinations of the foods above can create great meals that give you all the nutrients you need after exercise.
Here are a few examples of quick and easy meals to eat after your workout:
grilled chicken with roasted vegetables and rice
egg omelet with avocado spread on whole-grain toast
salmon with sweet potato
tuna salad sandwich on whole grain bread
tuna and crackers
oatmeal, whey protein, banana, and almonds
cottage cheese and fruits
pita and hummus
rice crackers and peanut butter
whole-grain toast and almond butter
cereal with dairy or soy milk
Greek yogurt, berries, and granola
protein shake and banana
quinoa bowl with sweet potatoes, berries, and pecans
whole grain crackers with string cheese and fruit
Make sure to drink plenty of water
It is important to drink plenty of water before and after your workout. Being properly hydrated ensures the optimal internal environment for your body to maximize results.
During exercise, you lose water and electrolytes through sweat. Replenishing these after a workout can help with recovery and performance (24Trusted Source).
It’s especially important to replenish fluids if your next exercise session is within 12 hours. Depending on the intensity of your workout, water or an electrolyte drink are recommended to replenish fluid losses.
The bottom line
Consuming a proper amount of carbs and protein after exercise is essential.
It stimulates muscle protein synthesis, improves recovery, and enhances performance during your next workout.
It is important not to go much longer than a few hours before refueling with a meal or snack.
Finally, replenishing lost water and electrolytes can complete the picture and help you maximize the benefits of your workout.
