5. How Much Protein Do You Need To Build Muscle?

When it comes to building muscle, protein intake is a crucial factor to consider. However, with various recommendations available, determining the right amount of protein can be confusing.

According to a systematic review and meta-analysis published in the Journal of the International Society of Sports Nutrition , it's suggested that adults should consume 1.6 to 2.2 grams of protein per kilogram of body weight per day to maximize muscle protein synthesis (MPS) and support muscle growth.

Additionally, research suggests that spreading protein consumption evenly throughout the day, rather than having large amounts at once, can be more effective for muscle building.

Combining protein intake with strength training exercises is essential to effectively build muscles. It is recommended that individuals should engage in resistance exercises, such as weightlifting or bodyweight at least two to three times per week.

In addition to protein and strength training, getting adequate rest and hydration is crucial for muscle growth. The adults should get seven to nine hours of sleep per night. Drinking plenty of water is also crucial for maintaining hydration, which is vital for muscle function.
