How Much Protein Is Needed to Build Muscle?

After determining your TDEE and establishing a calorie surplus, the next step is to calculate your daily protein requirements. Additional calories certainly help provide the energy needed to increase body weight.

However, a calorie surplus alone does not guarantee that the weight gained will be muscle mass. The body still requires sufficient protein intake to support muscle protein synthesis, post-workout recovery, and the formation of muscle tissue, especially if you regularly engage in resistance training.

Your protein target needs to be adjusted based on your body weight and divided across several meals to make it easier to meet throughout the day. You should also choose protein sources that are practical and fit your dietary habits so that your muscle gain goals are easier to maintain consistently.

Why is Protein Important for Building Muscle?

Protein is essential for building muscle because it provides the amino acids the body needs to repair and build muscle tissue.

It follows 3 simple steps:

1. Resistance training provides a stimulus to the muscles.

2. Protein provides amino acids.

3. The body then uses them to support muscle protein synthesis (MPS).

This process plays a role in muscle recovery and adaptation after exercise, including the increase in muscle size or hypertrophy. However, simply eating high amounts of protein does not automatically result in muscle growth.

Increased muscle mass is the result of a combination of exercise, nutrition, and recovery practiced consistently.

Exercise provides the stimulus, nutrition provides the necessary energy and nutrients, while recovery gives the body time to adapt. Thus, protein is a crucial part of the muscle-building process, but it still needs to be supported by a proper training and recovery regimen.

How Much Protein is Needed to Build Muscle?

For healthy adults who regularly lift weights and want to build muscle mass, the recommended protein intake is 1.6 - 2.2 grams per kilogram of body weight per day. The calculation is simple: body weight (kg) × 1.6 - 2.2 grams.

For example, if you weigh 70 kg, your daily protein requirement is around 112 - 154 grams (70 × 1.6 = 112 grams and 70 × 2.2 = 154 grams). A range is used because everyone’s needs differ based on body weight, training volume and intensity, total energy intake, training experience, and individual body response.

For context, the ISSN states that 1.4 - 2.0 g/kg/day is sufficient for most active individuals. Meta-analyses have also found that additional benefits for lean body mass begin to plateau around 1.6 g/kg/day during resistance training.

This means you do not need to immediately chase the highest possible protein numbers. If you weigh 50 kg, a practical target is around 80 - 110 grams/day. Once your protein needs are met, consuming significantly more protein will not automatically make your muscles grow faster.

Continue to combine sufficient daily protein intake with progressive resistance training, appropriate energy intake, and good recovery for the most optimal muscle-building process.

How to Distribute Protein Throughout the Day

The first thing you need to prioritize is meeting your total daily protein intake, rather than making meal timing overly rigid. Once you know your protein target, distribute the intake across several meals to make it easier to reach.

For example, if your requirement is 120 grams of protein per day, you could divide it into approximately 30 grams at breakfast, 30 grams at lunch, 25 grams as a snack, and 35 grams at dinner.

The amount of protein per meal does not have to be exactly the same every time. Protein distribution is intended to help you meet your daily needs consistently, not to create new, difficult-to-follow eating rules.

Adjust the distribution based on your schedule, portion sizes, and routines as long as your total daily protein goal is reached.

What Protein Sources Can Be Chosen for Muscle Gain?

1. Animal Protein

Animal protein can be a practical choice to support muscle gain because it generally contains complete protein with all the essential amino acids the body needs.

Some easily accessible sources include eggs, chicken, fish, meat, milk, and Greek yogurt. You can choose based on your daily protein requirements, food preferences, and budget.

There is no need to stick to one single protein source every day. Mix eggs or Greek yogurt for breakfast, chicken or meat for main meals, and fish as a variation to get a more diverse nutritional profile.

The most important factor for muscle gain is consistently meeting your total daily protein and energy requirements, rather than relying on one specific food.

2. Plant-Based Protein

Plant-based protein can be a viable choice to support muscle gain, especially from tempeh, tofu, soy, nuts, and legumes. You do not need to rely on one type of food every day.

Combine several protein sources to make your diet more varied while helping meet your needs for protein and other nutrients. Keep an eye on calorie counts, especially if you are in a calorie surplus to gain muscle mass.

High-protein foods still provide energy, and some sources like nuts are also quite high in fat and calories. Therefore, include protein in your daily calorie calculations so that your surplus remains controlled and aligned with your muscle gain goals.

Myths Vs Facts: Whey Protein in Muscle Building

1. Supplements Are Required to Build Muscle

Myth: Whey protein is mandatory for maximum muscle growth. Fact: Whey is not a primary requirement for building muscle. You can still meet your protein needs from foods like meat, fish, eggs, milk, tofu, or tempeh.

Whey is best used as a practical option to help meet daily protein targets when they are difficult to reach through food alone. For muscle gain, total daily protein intake is a more important factor than simply choosing between whey or whole foods.

The International Society of Sports Nutrition also emphasizes the importance of meeting total daily protein requirements and distributing them throughout the day to support muscle building, especially when combined with resistance training.

2. Whey Protein Damages the Kidneys

The assumption that whey protein inherently damages the kidneys is a myth. In healthy individuals with normal kidney function, a higher protein intake does not automatically cause kidney damage.

Whey protein itself is fundamentally a source of protein that helps meet daily requirements, not a substance that directly damages the kidneys.

For perspective, a study by Antonio et al. (2016) on resistance-trained men found that a high-protein diet of up to approximately 3.3 grams/kg of body weight per day for one year showed no detrimental changes to indicators of kidney or liver function.

However, these findings do not mean such amounts are necessary to build muscle or safe for everyone. If you have kidney disease or specific medical conditions, your protein needs should be determined in consultation with a doctor or nutritionist.

3. The Best Time to Drink Whey

Many people assume that whey protein must be consumed within 30 minutes after training for muscles to grow maximally. This assumption about a very narrow "anabolic window" is not entirely accurate.

You do not need to rush to drink whey immediately after your last set, as your body still has the opportunity to use protein for recovery and muscle building for several hours after training.

The more important factor is ensuring your total daily protein requirement is met and distributed well throughout the day. A meta-analysis by Schoenfeld et al. (2013) also showed that the benefit of protein timing on hypertrophy is highly influenced by total protein intake.

4. Whey Protein Makes You Fat

The belief that whey protein automatically makes you gain weight quickly is a myth. Whey is fundamentally a practical source of protein to help meet daily requirements.

Weight gain and body fat accumulation are more influenced by a calorie surplus sustained over a period of time, where energy intake is consistently higher than energy expenditure.

Protein also has a relatively high Thermic Effect of Food (TEF), about 20 - 30% of consumed energy, which is higher than carbohydrates and fats. This means the body uses more energy to digest and metabolize protein.

Even so, whey still contains calories, so the portion should be adjusted according to your daily protein requirements and calorie targets, especially when following a muscle gain program.

Protein Is Enough, Now the Body Needs Training Stimulus

Meeting protein requirements is an important step to support muscle gain, but the amount still needs to be adjusted according to body weight and individual needs. For healthy adults who regularly perform resistance training, a range of 1.6 - 2.2 grams of protein per kg of body weight per day can be used as a practical guide.

Choose a realistic target, distribute protein across several meals, and keep your intake aligned with your calorie surplus target so that your diet is easier to maintain consistently.

However, protein only provides the raw materials to build and repair muscle tissue. The body still requires a stimulus from resistance training for muscles to adapt and grow.

Once your protein requirements are met, the next focus is executing your training program consistently and applying progressive overload gradually, such as increasing weight, repetitions, or volume according to your capability.
