Not many are aware of the fact that protein is a crucial nutrient for building and maintaining muscle mass. When a person engages in physical activities like weightlifting or resistance training, these result in small tears in the muscle fibres. Proteins made up of amino acids, act as building blocks of muscle tissue and help these fibres to repair and grow stronger. However, the amount of protein required by the body depends on various factors like age, activity level, overall health and physical goals. 

Importance of Protein in Daily Diet

As discussed earlier, protein is made up of amino acids which fuel the cells and power the body to function properly. When you consume protein, your body breaks it down into amino acids, which are then used to repair and build muscles. Without adequate protein intake, your body may not have enough amino acids to repair and grow muscle tissue, which can lead to slower muscle growth and recovery.

Besides, protein also plays a role in regulating metabolism, supporting immune function, and maintaining overall health as it aids in carrying oxygen in your blood. Since the body fails to store protein, it becomes a necessity for people to consume protein daily. Especially athletes, bodybuilders, and individuals engaging in regular physical activity should have an adequate amount of protein in their daily diet.

How Much Protein Is Needed per Day To Build Muscles?

The daily protein consumption quantity depends on various factors like gender, age, health, activity level, etc. However, if you plan to build muscles, it is recommended to consume 1.2 to 1.6 grams of protein per kilogram (kg) of body weight each day. As per the American Dietetic Association (ADA), a person who is 30 years of age and measures 5ft 5inches (165.1cm) in height and 70 kg in weight should consume 70-126 grams of protein per day, given the fact that he/she exercises 4-5 times per week.

Besides, research also states that gradually increasing protein intake, paired with strength training, can help increase muscle mass.

Side Effects of Consuming Too Much Protein

Just like everything else, too much of anything causes more harm than good. The same goes for proteins. When you consume excess protein (more than 2 grams of protein per kg of body weight) on regular basis, this can result in escalating the metabolic burden on the liver, kidney, heart and bones, thereby increasing the chances of weight gain, intestinal discomfort and even liver and kidney disorders. Besides, high-protein intake without proper guidance can also increase the risk of coronary heart disease. Therefore, one should consult a dietician or expert before increasing protein intake.

Best Sources of Protein

Protein can be obtained from either animal or plant sources. As per some nutritionists, animal-based proteins are easy to digest as compared to plant-based proteins.

  • Animal-based proteins: lean meats, eggs, poultry, seafood, fish, dairy products, etc.
  • Plant-based proteins: beans, nuts, seeds, lentils, legumes, etc.

If you are someone who is physically active or recovering from muscle injuries, the right amount of protein intake daily can be of great help. However, it's also important to balance your protein intake with other nutrients like carbohydrates and healthy fats. A well-balanced diet is the ultimate key to supporting overall health and fitness goals. Therefore, before looking for the best protein diet for muscle gain, it is recommended to consult a dietician or medical professional.
