Do You Need to Eat Protein After a Workout?

It’s a common question that people ask about protein and working out. Do you need to eat protein after a workout?


Anyone who exercises regularly may be curious if they need to eat protein after a workout. The answer is, it depends. Protein plays a key role in muscle repair and growth; however, if you’re only doing light exercise—such as a leisurely jog—you don’t necessarily need to eat protein immediately after a workout. On the other hand, if you are lifting weights or doing strenuous workouts, you will probably benefit from consuming protein after your workout. Eating protein can help your body build and repair muscle tissue, prevent muscle injury, accelerate recovery and promote healthy weight loss. In this article we will explore the types of proteins available for post-workout consumption, how much to consume and when to eat it for best results.

What Is Protein?

Protein is a key nutrient that plays a major role in many body functions, including energy production, muscle building, and tissue repair. Protein provides amino acids, which are the building blocks of many tissues, including muscles and organs. Protein can also help with weight loss by providing satiety and helping to burn more calories. In this section, we will look at what protein is, why it is important and how it can help you achieve your fitness goals.

Types of Protein

Protein is a macronutrient that has many crucial roles in the body. It is made up of smaller molecules called amino acids, which are necessary for building and maintaining muscle, bone, skin and other tissues. Protein can be found in a variety of sources including animal-based foods such as dairy products, eggs, meat and fish as well as plant-based sources like legumes, nuts and seeds. The type of protein you choose depends on your personal health goals and preferences.

Animal Proteins: Animal proteins provide all nine essential amino acids our bodies need, which may make them the most complete protein source available. These include meats such as beef and pork; poultry such as chicken and turkey; seafood including tuna and salmon; dairy products like yogurt or cheese; eggs; whey protein powders from cow’s milk (in individual packets or powders usually mixed with water); casein powders from cow’s milk (also commonly found in protein bars); gelatin (usually used to make desserts); collagen supplements usually derived from cow hides, bones or fish scales.

Plant Proteins: Plant proteins are not considered complete since some may lack certain essential amino acids. Examples of plant-based proteins include lentils; chickpeas (also known as garbanzo beans); tofu; seitan (made from wheat gluten); tempeh (made from fermented soybeans); all types of nuts including almonds, cashews, pistachios and walnuts; nut butters such as peanut butter or almond butter; seeds such as sunflower seeds or pumpkin seeds; quinoa; spirulina powder ; edamame beans ; hemp oil ; mung bean sprouts ; green peas ; amaranth grain ; bulgur wheat(a type of whole wheat)

It is generally recommended to combine different plant proteins throughout the day to increase your overall intake of essential amino acids . Most plant proteins are low in one or more essential amino acid present in animal foods but adding complementary sources along with each meal can help close the gap.

Benefits of Protein

Protein is an essential macronutrient required by your body for growth and repair of body tissues. It is found in both animal sources, such as chicken, beef and dairy products, as well as plant sources such as nuts and legumes. Protein consists of combinations of amino acids that are necessary for the containment and transport of biologically important molecules within the body. The three primary benefits of consuming a sufficient amount of protein are:

1. Improved performance: Protein provides a necessary building block to facilitate muscle recovery following strenuous exercise, allowing athletes to develop greater strength and endurance over time.
2. Enhanced weight loss: Eating sufficient amounts of protein helps keep your metabolism running optimally while assisting with maintenance or reduction of fat stores; it also increases feelings of satiety when compared to carbohydrates or fats alone.
3. Improved immune system function: Protein helps protect against infection by supporting the development, distribution, and recovery/replacement capacity of red blood cells and white blood cells when faced with hazardous threats such as germs or toxins.

These benefits can be further realized when consuming high-quality proteins from complete sources like eggs, fish, poultry, beans or quinoa—as these types provide all the essential amino acids required by the body for effective tissue repair—as well as lesser quality incomplete proteins from plant sources that lack one or more essential amino acid. Although many people believe they need to consume protein in large portions following a workout routine in order to maximize results from their effort; however research has shown that optimal intake after exercise falls within 0.32-0.4 grams per kg (or 0-7mg/kg) body weight at serum levels 4 hours after exercising with no additional benefit coming past 6 hours post exercise.(References).

Does Eating Protein After a Workout Help?

Protein is essential for muscle growth, repair and rebuilding. Eating protein after a workout can help to replenish your body’s resources, but is it really necessary? This article will examine the evidence around eating protein after a workout, and address the pros and cons to help you decide whether to make it part of your routine.

What Studies Say

It is a common belief that consuming protein after exercise is essential to build muscle mass and recover quickly; however, studies have shown that eating protein right after a workout may not always be necessary. An in-depth review of recent research on the physiological effects of exercise-induced stress on muscle protein metabolism stated that although it is important to consume adequate amounts of dietary protein throughout the day to optimize gains, post-workout consumption might be unnecessary when overall energy balance is appropriate.

The authors concluded that “timing of nutrient intake around exercise does not appear to be important…as long as dietary intake is sufficient over the entire day.” Additionally, several other studies have indicated that resistance training without additional post-workout protein had similar or greater effects on muscle development and performance than with additional supplementation after workouts.

In conclusion, it appears from current scientific evidence that consuming sufficient amounts of dietary protein throughout each day can provide your body with all the nutrients needed for optimal post-exercise recovery and growth. Eating protein shortly after exercising may contribute to your overall dietary balance; however, it doesn’t appear to be necessary for most people for optimal results.

What Experts Recommend

Consuming the right amount of protein after a workout is essential for muscle growth and recovery. But not all forms of protein are equal when it comes to post-workout benefits. For example, research shows that whey protein is one of the best sources of post-workout protein because it contains all essential amino acids and is quickly digested by your body.

Experts recommend that you eat at least 0.14–0.23 grams of protein per pound (0.3–0.5 grams/kg) of body weight shortly after a workout to help ensure optimal performance and progress with your fitness goals. That translates to about 20–40 grams of high-quality proteins for most people, depending on their body weight and activity level. Eating the right types of proteins within 30 minutes after a workout has been shown to be particularly beneficial for muscle growth and repair.

In addition to whey protein, other sources high in essential amino acids that are great for post-exercise recovery include: eggs, nonfat Greek yogurt, lowfat cottage cheese, salmon, whitefish and tuna; lentils; hemp seeds; quinoa; chickpeas; edamame soybeans; almond butter or nut butter spread on whole grain toast/wraps; plant-based proteins like spirulina or pea protein powder added to smoothies or post-workout drinks; beef jerky with no added sugar; walnuts or other nuts like almonds and pistachios (as long as they are unsalted). It’s also important to stay hydrated throughout your workouts by drinking plenty of water before and after physical activities in order to maximize recovery time as well as overall health benefits from exercising regularly.

How Much Protein Should You Eat After a Workout?

After a hard workout, it is important to refuel your body with the correct nutrients so that you can recover quickly and maximize your potential. Protein is one of the main nutrients that should be consumed post-workout. But how much protein should you eat after a workout? Let’s explore the science behind protein intake after a workout and what the best options are.

Calculating Protein Needs

Though individual levels of protein may vary depending on a number of factors, most experts recommend that you aim to consume between 0.14 and 0.23 grams of protein per pound (0.3–0.5 grams/kg) of body weight each day to support muscle growth and recovery after exercise. To maximize your recovery during periods where you are training more intensely, like after a tough workout or in the midst of marathon training season, it is important to meet your daily protein needs.

Calculating your exact protein needs can be complicated since there is not an absolute answer for all individuals; however, you can use an equation provided by the International Society of Sports Nutrition (ISSN) to help estimate how much protein your body needs each day:

Protein Intake = Body Weight (in kg) X Activity Factor (1-2 grams/kg/day)

To adapt this equation for our purposes here, for post-exercise nutrition we want to aim for 1.4-2 g/kgBW/day if engaging in resistance exercise daily or 2 g/kgBW/day if engaging in vigorous intensity endurance exercise weekly or high intensity resistance training twice weekly. This means that someone weighing 70 kg who trains twice a week would require 140 g of protein each day while someone who weighs 70 kg and trains four times a week would need 200 g per day.

Protein Sources

The importance of consuming protein shortly after a workout cannot be overstated. Protein aids the body in repairing itself so it can recover stronger, faster, and better than before. Knowing what types of foods are good sources of protein can help you determine what to eat after a workout to optimize recovery and results.

Good sources of protein include lean meats such as poultry, fish, eggs and low-fat dairy products as well as plant-based proteins like tofu, edamame, nuts/seeds, legumes (beans and peas). If you choose an animal source of protein make sure that it is lean or has been trimmed off all visible fat. You can calculate how much protein you need to meet your individual needs based on your weight and activity level.

In addition to foods rich in complete proteins such as those outlined above, athletes may also benefit from supplementing with plant-based complete proteins like soy or hemp seed powder. These powders contain all the essential amino acids needed for muscle growth and repair and are easiest on digestive systems since many animal proteins require further digestion prior entering into the bloodstream where they can be used by muscles. Protein shakes that combine rice or pea base with added flavoring are also becoming increasingly popular post-workout snacks because they provide both complete proteins combined with carbohydrates for quick energy absorption.


In conclusion, the best time to eat protein after a workout is 1-2 hours after you finish. Protein is important for muscle growth and repair, and it’s also important for optimal performance. Eating protein within this time frame will help your body make the most of the benefits it has to offer.

It’s generally best to pair your post-workout meals with complex carbohydrates as well as fats, in order to properly fuel your body and provide it with the energy necessary to continue functioning optimally. It can also help balance out your body’s intake of nutrients and prevent a spike in insulin levels, which can cause fatigue or hunger later on. Even if you can’t eat within 1-2 hours after a workout, try to have at least something small; this will ensure some amino acids reach your muscles during their peak absorption window.
