Is It Bad to Not Have Protein After a Workout?

You probably know that protein is an essential part of a healthy diet. But what you may not know is how important it is to consume protein after a workout.


When it comes to working out, protein is often the key ingredient in any program. Protein is important for muscle growth, repair, and development. Even so, many people wonder if it is okay to not have protein after a workout. The answer is dependent on individual goals and depends on the type of workout as well. This article will cover the possible effects of not having proteins after a workout and provide tips on how to maximize performance in order to achieve desired results.

What is Protein?

Protein, an important macronutrient, is an essential component for providing energy, building and repairing muscle, and promoting overall health. Not only can it help with muscle repair and development, but it also helps regulate many bodily functions, such as food digestion and hormone production. Protein can be found in many different sources, such as meat, dairy, eggs, fish, and plant-based proteins. In this article, we will discuss what protein is and how important it is to consume it after a workout.

Benefits of Protein

Protein is an essential nutrient for our bodies. It is found in a variety of foods, including meat, dairy, legumes, nuts, soy products and grains. Protein helps build muscle and repair tissue; it also carries oxygen and nutrients to cells throughout the body. It is important for growth and maintenance of healthy bones, cartilage, skin and blood. In addition to its role in building muscle mass, protein has many other important functions in your body.

Protein plays a role in the metabolism of carbohydrates and fats; it helps create hormones that regulate many bodily processes; it provides energy during exercise; and it helps form the enzymes that are needed to break down food molecules into useable molecules for the body. It’s also necessary for building and repairing skin tissue — including damaged or wounded skin — as well as nails, eyesight lenses and hair follicles.

Getting enough protein after exercise is important because it helps repair damaged muscle tissue while providing your body with energy to help refuel before your next workout session. A few sources of protein include low-fat dairy brands such as skim milk or yogurt; lean sources of meat such as chicken or fish; dark leafy greens like spinach or kale; beans such as lentils or chickpeas; nuts like almonds or walnuts; seeds such as pumpkin or sunflower seeds; and some grains such as quinoa or bulgur wheat.

Types of Protein

Protein is one of the three essential macronutrients — along with fat and carbohydrates — that the body needs to build and maintain lean muscle mass, bones, connective tissue and more. There are several types of protein available to help nourish our bodies.

Animal-Based Proteins: Animal-based proteins, such as beef, poultry, fish, dairy foods and eggs, are considered complete proteins because they contain all nine amino acids that are essential for muscle growth and recovery. They are an excellent choice post-workout.

Vegetable-Based Proteins: Vegetable-based sources like beans, peas and nuts also provide some of the essential amino acids required for muscle recovery after a workout. That said; plant proteins typically have fewer total amino acids than animal-based proteins do. To get the most out of your vegetable proteins, eat a variety of sources throughout the day (e.g., almonds for lunch; chickpeas for dinner).

Soy Protein: Soy protein is known for packing a punch when it comes to quality protein— this legume provides both a complete source and isoflavones that may protect against numerous health conditions from metabolic syndrome to hormone-dependent cancers. The downside? Some people find its flavor overwhelming or unappealing while others experience symptoms like headache or nausea when they consume too much soy protein at once.

Rice Protein: While research on rice powders is limited compared to grassfed whey or casein powders — which contain all 9 essential aminos — many people like using this vegan alternative since it’s gentle on those with allergies or sensitivities to dairy products and egg whites. Because rice has fewer aminos than other sources (7 in total), it’s important to pair rice protein with another source in order to get all 9 necessary aminos in your diet each day.

Casein Protein: Casein makes up around 80% of milk’s protein content; it’s also found in powder form as an animal based product derived from cow’s milk with minimal processing involved before reaching store shelves (it cuts right through regular pasteurization!). Consuming casein pre-bedtime can help build muscle overnight due to its slow digestion rate compared to quickly digesting whey; however if purchased after expiration date stored incorrectly it can cause alarming levels of foodborne infections due risk contamination levels not caught by regular pasteurization methods employed during production steps greatly reducing quality finally consumed by customers putting them at risk infection causing agents even death!

What Happens if You Don’t Consume Protein After a Workout?

After a workout, consuming protein can help your body recover and build muscle. Consuming protein shortly after a workout can provide your body with the essential amino acids it needs to repair and rebuild muscle. However, not consuming protein after a workout can affect your body’s recovery and muscle growth. In this article, we’ll discuss the effects of not consuming protein after a workout.

Muscle Protein Synthesis

Research has demonstrated that after a workout, consuming protein can lead to increased muscle protein synthesis. Muscle protein synthesis is the process of building and repairing muscles by providing them with amino acids and other vital proteins. Although you may have heard that it’s beneficial to consume 20-40 grams of protein within 30 minutes for maximum benefit, recent research suggests that muscle protein synthesis increases up to three to five hours following a workout. After that time period, muscle mass begins declining from the catabolic state until it reaches the pre-workout level again.

In short, not consuming adequate amounts of protein after a workout can drastically reduce muscle protein synthesis and impede muscle growth and repair. Additionally, studies suggest that failing to consume enough post-workout nutrition may reduce gains in strength capacity as well as lean body mass over time. Furthermore, failure to consume post-workout nutrition may also increase cortisol levels, which can lead to decreased rates of recovery and higher levels of perceived stress on the body.

Muscle Damage

One of the main consequences of not consuming protein after a workout is diminished muscle repair and muscle damage. When you work out, your body uses energy in the form of glycogen, which is stored in the muscles. But when glycogen stores are depleted during intense exercise, your body starts to break down protein to fuel itself. This can lead to increased muscle soreness and fatigue, as well as increased damage or tears in the muscles. Consuming protein post-workout helps replace and rebuild this lost muscle protein, so that bigger and stronger muscles can be produced. Protein also helps to increase metabolic rate, which adds to greater calorie burn as well as fat burning potential.


Not consuming adequate protein after a workout has a number of negative effects. One of the most noticeable consequences is fatigue. Even moderate amounts of exercise can quickly drain muscle and glycogen stores, resulting in feelings of mental and physical exhaustion. Refueling the body with adequate protein is essential to maintaining energy levels. Without enough protein post-workout, fatigue will become an issue that makes it hard to continue exercising or carrying out everyday activities.

Furthermore, without adequate post-workout nutrition, your recovery time will be significantly longer than it needs to be. Muscular damage incurred during exercise can be reduced by taking in a meal shortly afterward that has between 10-20g of quality complete protein sources such as whey or casein. In addition to aiding in muscle recovery and growth, protein can help protect against catabolism where your body breaks down the muscle fibers used during intense physical activity for energy fuel instead.

How Much Protein Should You Eat After a Workout?

We all know that protein is essential for muscle growth, but the question remains: how much protein should you eat after a workout? Eating the right amount of protein after a workout can help you maximize your gains, while too little or too much can be detrimental. In this article, we’ll discuss the science behind why you need protein after a workout and provide you with the best guidelines to ensure you get the most out of your workout.

It is well recognized that protein plays a significant role in muscle repair and recovery after exercise. Protein should be consumed shortly after your workout to maximize its benefits. To help you determine the ideal amount of protein to consume post-workout, consider the following recommendations:

For intense workouts (such as weightlifting or resistance training), aim for 0.25 – 0.40 grams of protein per pound of bodyweight up to one hour after exercising.
For moderately intense workouts (such as a 15 – 45-minute cardio session or a 30-60-minute resistance circuit), aim for 0.15 – 0.30 grams of protein per pound of bodyweight up to two hours after exercising.

Consuming adequate amounts of quality protein following an exercise session is essential for optimal recovery, since it helps repair and rebuild damaged muscle cells and provide fuel for renewed energy production. Good sources of post-workout proteins include lean red meat, poultry, low fat dairy products (like cottage cheese and Greek yogurt), whey protein powder shakes, tofu, legumes and eggs.

Protein Timing

The timing of your protein consumption around workouts is important. Studies show that using protein soon after your workout can increase the rate of muscle growth and development when consumed regularly in conjunction with resistance training. Generally, it’s recommended to consume a source of protein within 30 minutes of exercise to take advantage of this effect. In that time frame, you should aim for about 20–40 grams of protein for optimal results.

The sources of this post-workout fuel can vary widely — from whole foods like dairy, eggs and fish to shakes and bars made with high quality protein powders or plant-based proteins like hemp and pea. If you’re bulking up or trying to add lean muscle mass, moderation is key: Protein should make up no more than 20–25% of your total daily nutrition plan; any excess will be turned into energy or stored as fat. It’s also important to hydrate after exercises — with water or sports drinks — as dehydration can limit muscle growth and leave you feeling fatigued.


In conclusion, it is not necessary to consume protein or any nutrients directly after a workout. Research suggests that consuming protein within an hour after a workout can increase muscle growth. However, it is not necessary for you to have protein post-workout in order to see results. Additionally, there may be benefits to delaying your post-workout meal, such as enhanced satiety from the meal following the workout-related delay in eating. Ultimately, balancing overall nutrition and timing of meals in order to meet individual goals is key for successful health outcomes.
