How Soon After a Workout Should You Eat Protein?

It is often recommended that you eat protein soon after a workout. But how soon is too soon? And how much protein do you need?


Regular exercise is a key factor for optimal physical health, but how soon you eat protein after a workout can make all the difference. Eating protein within an hour after working out helps to maximize your muscle growth and repair efforts. Understanding the importance of when to consume protein is essential for athletes and those who are trying to increase their fitness levels.

When we exercise, our body keeps track of the physical demands that it undergoes. Part of that process is initiating a number of processes in our bodies to help promote recovery, like reducing inflammation and repairing muscle fibers. Consuming food within an hour after a workout helps kickstart these processes and provides your body with the nutrients it needs to effectively recover from your workout. Protein, in particular, has been proven to be incredibly beneficial for athletes and non-athletes who are looking to build or maintain muscle mass or strength.

Benefits of Eating Protein Soon After Exercise

Eating a source of protein soon after exercise has been found to improve the recovery process and enhances muscle growth. Protein helps rebuild muscle, improve protein synthesis, and speeds up recovery. Additionally, it can help replenish glycogen, which is the energy source the body uses during a workout. Let’s explore the benefits of eating protein soon after a workout.

Repair and rebuild muscle

Consuming protein soon after a workout helps to repair and rebuild muscle tissues, which in turn increases the strength of your muscles. Protein is a key source of amino acids, which are the building blocks of muscles. Depending on the type and intensity of your workout, you may need anywhere from 10 to 25 grams of protein to replenish and repair muscle tissue. Eating protein soon after exercising helps to kickstart this process. Furthermore, consuming carbohydrates around your workout can help replenish energy stores and ensure that adequate protein reaches your damaged muscles for repairs.

Replenish glycogen stores

Replenishing glycogen stores is one of the major benefits of eating protein soon after exercise. Glycogen is the stored form of carbohydrate that your muscles rely on to refuel after working out. After a workout, your muscles are depleted of energy and need to be replenished with carbohydrates. Eating protein soon after exercise can help restore your glycogen levels, allowing you to get the most out of each workout session. When you eat protein soon after exercise, it helps stimulate the process known as glycogenesis, which is the creation of new glycogen molecules from glucose or other smaller carbohydrates. This is an important part of replenishing your body’s energy stores after working out and helps ensure that you can maintain a healthy level of performance for each session.

Increase satiety

One of the noted benefits of eating protein soon after exercise is increased satiety (feeling fuller), which can assist with weight management. This feeling of fullness can help to reduce calorie intake in later meals, making it easier to stick to a diet plan. Eating protein-rich foods soon after exercise can also lead to improved metabolic health, as these foods help the body more effectively recover and repair after physical activity. Research has shown that consuming 20 grams of protein post-workout increases muscle protein synthesis, resulting in more efficient muscle recovery and growth. Protein has also been noted for its anti-inflammatory benefits, helping reduce soreness caused by intense workouts while also providing antioxidants that help scavenge free radicals brought on by strenuous activity — leading to less fatigue and faster injury recovery.

Timing of Protein Intake

Timing your meals and snacks to ensure that your body gets the necessary nutrients to help it recover is critical to achieving good results with exercise. In particular, protein intake after a workout can provide important support for muscle recovery and growth. But when exactly should you be eating it? Let’s explore the benefits of timing your protein intake after exercise.

Immediately after exercise

Eating protein within a few hours post-workout is important for recovery. Protein intake following exercise helps to support muscle-building and encourages adaptation to the workout. Many people wonder how soon after exercising they should drink a protein shake or eat a meal that contains protein. It is recommended that for optimal performance, individuals try to aim for an immediate post-exercise intake of 15-25g of quality protein as soon as possible following the workout.

Depending on your fitness goals and personal preference, you can choose from various sources of quality proteins such as whole foods like eggs, yogurt, and quinoa; white meats such as chicken, turkey breast, and shrimp; red meats such as steak cuts or ground beef; dairy sources like milk or plant-based nut milks. Additionally, high-quality supplemental forms like whey isolates are popular options among athletes due to their fast absorption speed prior to beginning the process of muscle synthesis and replenishment.

For those short on time or dislike blending shakes at the gym, other convenient options include energy bars and ready-to-eat meals containing substantial amounts of quality proteins like tuna sandwiches on whole wheat bread or overnight oats prepared with Greek yogurt topped with fresh fruits are also good sources to consider after exercise sessions. Ultimately, it is essential to keep in mind that one must consume sufficient amounts of quality proteins consistently along with adequate calorie intake for both gaining muscle mass after workouts yet also keeping off any potential added fat accumulation from inactive periods throughout the day due to sedentary lifestyle habits.

Within 30 minutes of exercise

When it comes to timing of protein intake, research suggests that consuming protein within 30 minutes after exercise is ideal for maximizing muscle gain and recovery. During this highly anabolic window, consuming a combination of proteins and carbohydrates can help increase muscle protein synthesis.

The type of proteins consumed also matters. Both whey and casein proteins provide the essential amino acids required for muscle repair and growth. Whey is a fast-digesting protein, while casein is slower-digesting. Consequently, both are beneficial to have in one’s diet following a workout. Consuming carbohydrates at the same time as proteins may help the body to better utilize the nutrients by restricting breakdown of muscle tissue for energy during intense workouts.

Ideally, individuals should try to consume 20-25 grams (for women) or 40-50 grams (for men) of quality lean protein within 30 minutes after exercising. Examples of lean protein sources include chicken breast, salmon, tuna, tilapia, cod fish or lean beef cuts like top sirloin steak or filet mignon. Nutritional bars with high quality whey and/or casein can also be used as a convenient source of fast-acting post exercise nutrition if desired.

Types of Protein

Protein is one of the most important nutrients for building and repairing muscle. Consuming protein after a workout helps to promote muscle recovery and growth. When it comes to choosing a protein source, there are a range of different types available. Depending on your goals and dietary restrictions, there are a number of protein options that you can choose from. Here are some of the most popular types.


Whey is a complete protein consisting of all nine essential amino acids. It’s found naturally in cow’s milk, and it’s the liquid that separates from the coagulated curds during cheese creation. Whey protein usually comes in three forms: whey concentrate, whey isolate, and whey hydrolysate. All three are created with the same process but differ in the amount of processing they undergo.Whey concentrate has around 70–85% protein content and is a great option for those who prioritize convenience since it’s quickly absorbed into the body to jump-start muscle recovery and support muscle growth after exercise. Whey isolate is around 95% protein content, making it more concentrated than whey concentrate, so it contains fewer lactose and fat molecules. Plus, because of its lower lactose levels than whey concentrate or hydrolysate, it’s often better tolerated by those who are lactose sensitive. Finally, there’s whey hydrolysate—often referred to as ‘hydrolyzed-whey’—which has undergone pre-digestion for enhanced digestibility of proteins since these molecules are already broken down into smaller chains of amino acids that enter circulation more quickly than their fully intact counterparts.


Casein is the other main protein found in dairy products. It’s also a complete protein, meaning it contains all of the essential amino acids your body needs. Unlike whey, casein is digested more slowly and releases its amino acids over several hours, which helps your muscles stay fueled for longer. This makes casein a popular choice for athletes and bodybuilders looking to fuel their muscles throughout an extended time period like overnight. Common sources of casein include dairy products such as milk, yogurt, cheese, and cottage cheese. Plant-based sources include quinoa, amaranth, soy milk, and some nut milks like cashew or almond milk.

Plant-based proteins

Plant-based proteins are an excellent source of protein for those on vegetarian or vegan diets. They tend to provide less calories and fat than animal proteins and also contain fiber, complex carbohydrates, vitamins, minerals, and other beneficial phytonutrients. Common types of plant-based proteins include legumes like beans, peas, lentils and chickpeas; whole grains like oats, quinoa and buckwheat; nuts and seeds like almonds, walnuts and chia seeds; as well as plant-based protein powders such as hemp protein powder or brown rice protein powder. Plant based proteins should be paired with other foods such as vegetables for a balanced meal. Eating plant-based proteins soon after a workout will help replenish your muscle’s glycogen stores – an essential part of recovery after an intense workout.


At the end of the day, how soon after a workout you should consume protein comes down to how much time you have before your next meal. If your next meal is more than four hours away, it’s best to take in some quickly-digested protein within two hours after exercising. Whether you choose whey protein or other sources of high-quality protein such as dairy, eggs, meat, or poultry will depend on when and where you’re eating, your individual nutritional preferences and what’s most available to you.

No matter what type of protein source you choose after working out, ensure that it contains adequate amounts of complete proteins since they give your body all the building blocks necessary for muscle growth and repair. For example, whey is one of these complete proteins as are egg proteins. In contrast, vegan proteins such as hemp and pea often lack one or more essential amino acids. That’s why it’s important to look beyond just intake time when choosing which kind of protein shake or snack your post-workout meal will include.
