What is my optimal protein intake for muscle growth?

Protein is vital for a number of bodily functions, including hormone production, muscle repair, healthy immune system function, and more. The amount of protein you need depends on many factors, including your physiology, health goals, and activity level. At Evidation, we're here to help you meet all of your health goals. Here, we'll explore how you can calculate your personal protein intake needs if you're working toward muscle gain.

Protein and gender

Gender can have an influence on protein requirements, but biological sex alone doesn’t determine the amount of protein that a person needs in order to gain muscle. While men typically have a higher amount of lean muscle mass than women, this isn't always the case. Individual protein needs can vary depending on muscle mass, goals, and life circumstances (for example, protein needs change during pregnancy and menopause). Men typically require more protein than women to gain muscle mass, but it's important to consider many factors to determine the right amount of protein for you.

Genes and the gym: How genetics play a role in building muscle

While your physical makeup is not solely determined by genetics, your genes play a significant role in your body's protein metabolism and ability to develop and maintain muscle mass.

Some genetic factors that can influence how much protein you'll need in order to gain muscle include:

• Muscle fiber composition: Muscles are mainly made up of two types of fibers: slow-twitch and fast-twitch. Each type is designed for different activities. Slow-twitch fibers are designed for sustained athletic efforts, like long-distance running or swimming, while fast-twitch fibers are designed for power and speed, and are used in activities like weightlifting and sprinting. The ratio of slow-twitch versus fast-twitch muscle fibers each person is born with varies from one individual to the next. The amount of slow-twitch (endurance) and fast-twitch (strength and explosive movement) muscle fibers you have influences the way your body repairs and recovers following a tough workout, which can influence the amount of protein you need to build muscle.
• Protein processing: Your genes can influence how well your body absorbs and uses protein. If your body is more efficient than others when it comes to digesting and using protein, you may not need a super-high protein intake in order to gain muscle.
• Body composition: People who have more lean muscle mass require more protein to both maintain and build muscle. If you naturally have a more muscular body type, you'll likely need to more drastically boost your protein intake in order to gain muscle than someone who has a less muscular body type.

Protein requirements for muscle growth: calculating your needs

You may need to go through some trial and error to figure out exactly what protein levels help you move toward your goals, but understanding general guidelines can be a good place to start.

It's recommended that adults consume .35g of protein per pound of body weight to maintain general good health. If you're physically active, it's recommended that you consume 0.5 to 0.9g of protein per pound of body weight. Many people swear by eating 1g of protein per pound of body weight to build muscle and help with satiety%20increased%20thermogenesis%E2%80%94higher%2Dprotein) if you're eating a fairly low-carb diet. While this isn't a bad rule, it can take some time to work up to such a high protein intake.

Eating protein at the right time is just as important as eating protein in the right amount. If you want to build muscle, you'll want to consume 15 to 25g of protein immediately after your daily workout in order to stimulate muscle growth (this counts toward your protein total for the day).

Enjoying high-protein foods

Ready to boost your daily protein intake? We've got you. Try these foods to enjoy delicious meals while getting the protein you need to build muscle:

• Eggs (6.3g of protein each)
• Almonds (6g of protein per ounce)
• Pistachios (5.7g of protein per ounce)
• Chicken breast (26.7g of protein for half of a chicken breast)
• Cottage cheese (28g of protein per cup)
• Greek yogurt (20g of protein per 7-oz. container)
• Milk (8g of protein per cup)
• Lean beef (25g of protein per 3 oz. serving)
• Quinoa (8g of protein per cup)
• Ezekiel bread (6g of protein per slice)

Progressive overload: Making the most of your time in the gym

Once you start regularly eating a protein-rich, muscle-building diet, you'll want to make sure you're putting your hard work in the kitchen to good use fueling your workouts in the gym. Progressive overload—resistance training that gradually becomes more intense over time—continually challenges your muscles. When your muscles have to constantly adapt to new tempos, higher weights, or increased repetitions, you'll get to reap the benefits of your high-protein diet.

It's important to increase your strength training safely and gradually to ensure that your program meets you at the nexus of challenge and ability. Pushing yourself too hard can lead to burnout and injury. If you're new to strength training, working with a personal trainer can help you move through a progressive overload program at a pace that's appropriate for your needs. If you're experienced and ready to tackle progressive overload workouts on your own, you'll want to follow a workout program that increases time, weight, or workout intensity by 10% or less each week to keep you safe as your muscles grow.
