Building Muscle: Does Diet Play A Role?

does diet help build muscle

Diet is an important factor in building muscle. While resistance training and adequate rest are key, nutrition is also essential. A balanced diet that includes protein-rich foods, such as meat, poultry, and fish, dairy, and plant-based sources, is crucial for muscle growth and repair. In addition, consuming a variety of whole foods ensures adequate intake of vitamins and minerals, supporting overall health and muscle-building capabilities. Caloric intake is also significant, with a surplus of calories fuelling workouts and providing the building blocks for muscle growth. However, it is important to note that overeating can lead to increased body fat, so a well-planned diet that considers protein timing and quality, along with the right mix of carbohydrates and healthy fats, is vital for optimising muscle growth and maintaining overall health.

Consume enough protein

Consuming enough protein is essential for muscle growth and maintenance. Protein is the building block for muscles and is found in every cell and tissue in the body. When you exercise, your muscles and their proteins break down, and replacing them with new protein helps your body recover from exercise, repairing muscles and helping them get stronger.

The amount of protein required to build muscle varies depending on several factors, including age, gender, activity level, health, and other variables. However, most studies agree that higher protein intakes are associated with improvements in lean body mass and strength when combined with resistance training. The current Recommended Dietary Allowance (RDA) for protein is 0.8 grams of protein per kilogram of body weight, but this is the minimum amount required to prevent lean body mass loss and most people need more, especially if they exercise regularly. The Food and Nutrition Board of the Institute of Medicine and the American College of Sports Medicine recommend a higher range of 1.2 to 1.7 grams of protein per kilogram of body weight per day. Endurance or strength athletes should aim for 1.2 to 2 grams of protein per kilogram of body weight daily.

To ensure you are consuming enough protein, it is recommended to eat protein-rich foods consistently throughout the day. Your first meal of the day should contain at least 30 grams of protein, followed by another 30 grams with each subsequent meal. Additionally, include protein-rich snacks throughout the day, such as protein bars, homemade protein balls, cottage cheese, or meat sticks. Aim to consume at least 15 to 25 grams of protein within 2 hours after exercising to help stimulate muscle growth.

If you are struggling to get enough protein from foods, protein shakes and supplements can help increase your protein intake. Dairy protein powders, such as whey and casein, are popular options, but other protein powders use soy, pea, beef, or chicken protein. Creatine supplements can also give your muscles the energy to perform additional reps during workouts.

While consuming enough protein is crucial for muscle growth, it is important to note that strength training plays an equally important role. To build muscle effectively, you need to combine a high-protein diet with resistance training to break down muscle fibers and stimulate muscle growth.

Eat a balanced diet

Eating a balanced diet is essential for anyone looking to build muscle. While lifting weights and resistance training are crucial components of building muscle mass, a well-rounded diet provides the energy and nutrients needed to support muscle growth and overall health.

A balanced diet for muscle building should include a range of protein-rich foods, such as meat, poultry, and fish, dairy, and plant-based sources like beans, edamame, and peanuts. Protein is essential for muscle repair and growth, and spreading protein consumption evenly throughout the day maximises muscle protein synthesis. In addition to protein, a balanced diet should include a mix of carbohydrates, fats, vitamins, and minerals. Carbohydrates such as squash, sweet potatoes, and brown rice provide energy for workouts, while healthy fats like those found in peanuts and almonds help fuel the body and support overall health.

Iron is another important component of a muscle-building diet. It plays a crucial role in the function of organs, bones, and muscles, and iron deficiency can impair these functions. Vitamin B12 is also key, as it supports the health of blood cells and nerves, enabling you to perform the exercises needed to build muscle.

For those looking to build muscle, it's important to consume a calorie surplus. This provides the body with the energy needed to build new muscle tissue. However, overeating can lead to a rapid increase in body fat, so it's important to be mindful of macronutrient sources. While protein, carbohydrates, and fats all contribute calories, a focus on excess protein is less likely to result in fat storage, according to Dr. Nadolsky.

In addition to whole foods, dietary supplements can support muscle growth when paired with a focused diet and exercise program. Creatine, for example, can provide muscles with the energy to perform additional reps, aiding in muscle growth. Similarly, protein powders can help increase protein intake, with popular options including whey, casein, soy, pea, beef, and chicken.

Include supplements

Dietary supplements can help increase muscle mass and strength when used with a focused diet and exercise program. However, it is important to note that the body can only process a certain amount of protein at any given time. For instance, the body can process about 30 grams of protein in one sitting. Therefore, if you are already consuming a balanced meal with more than 30 grams of protein, adding a protein shake with 40 grams of protein per serving will not increase muscle mass. Instead, the body will treat the excess protein as more calories.

Creatine is a popular supplement that can be beneficial for muscle growth. Creatine is a molecule naturally produced in the body that provides energy for the muscles and other tissues. Taking it as a supplement can increase muscle creatine content, which improves muscle strength and leads to larger increases in muscle mass over time. Creatine is particularly beneficial for vegetarians and vegans, as they do not get creatine through animal-based sources. However, it is important to note that creatine use may cause side effects, and it is always recommended to consult a healthcare provider before taking any supplements.

Beta-hydroxy beta-methylbutyrate (HMB) is another supplement that may be beneficial for muscle growth. HMB is a molecule produced when the body processes the amino acid leucine, and it is responsible for some of the beneficial effects of protein and leucine in the diet. Taking HMB as a supplement allows for higher levels, which may benefit muscle growth. Research has shown that taking 3 to 6 grams of HMB per day can improve lean body mass gains from weight training, especially for previously untrained adults.

While supplements can be beneficial, it is important to prioritize a well-rounded diet that includes a variety of protein-rich foods, such as meats, poultry, and fish, dairy, and plant-based sources like soybeans and peas. In addition, carbohydrates are crucial for muscle repair as they provide the energy substrate for cell metabolism. By focusing on a balanced diet and incorporating specific supplements under the guidance of a healthcare professional, individuals can effectively support their muscle-building goals.

Eat before training

Eating before training is important for maximising performance and speeding up recovery. The food you eat before a workout can also help to burn fat, build muscle, and prepare your body to recover from exercise.

The International Society of Sports Nutrition (ISSN) notes that the degree to which carbohydrates are used during exercise depends on several factors, such as the intensity, type of training, and overall diet. Consuming carbohydrates before your workout is important for boosting long-duration exercise performance. Research has shown that consuming 15 to 25 grams of carbohydrates before a workout can help you train longer and more intensely. Carbohydrates are an essential source of energy and consuming the right amount before a workout ensures that your body has enough fuel to perform well.

Protein is also essential for building muscle. Consuming 20–30 grams of protein before a workout can increase the rate of muscle protein synthesis for several hours. This process involves amino acids, the building blocks of protein, being formed into muscle proteins or muscle mass. Eating a meal with a significant amount of lean protein before exercising can help improve performance. Consuming high-protein foods such as salmon before a workout can increase muscle mass gains.

In addition to carbohydrates and protein, other nutrients can also help with muscle building. For example, peanuts contain a mix of protein, fat, and carbohydrates, as well as a high number of calories, which can be beneficial if you are trying to gain muscle. Dairy products such as cottage cheese can also be incorporated into your diet, with higher-fat versions providing more calories. Iron is another important nutrient, as it is used to store and transport oxygen in your blood and muscles, and a deficiency can impair these functions.

Supplements can also help enhance performance, improve strength, increase lean muscle mass, and reduce fatigue. Creatine, for example, can give your muscles the energy to perform additional reps. It is important to speak with a healthcare professional before taking supplements to avoid possible side effects and determine the best dosage.

Track your calories

Tracking your calories is a great way to ensure you are eating the right amount of food to build muscle. It can be time-consuming, but it is a good way to gain a detailed understanding of your nutritional needs.

Firstly, it is important to understand your TDEE (Total Daily Energy Expenditure). This is the number of calories you need each day to maintain your body weight. You can calculate this using a calorie calculator, which will take into account your body fat percentage, weight, and activity levels. Once you know your TDEE, you can adjust your calorie intake depending on whether you want to gain or lose weight.

If you want to build muscle, you will likely want to be in a calorie surplus. This means eating more calories than your TDEE. A good rule of thumb is to aim for a surplus of around 400 calories per day. This will allow you to build muscle without gaining too much body fat. However, be aware that eating in a smaller surplus will slow down your rate of muscle growth.

You can use a calorie tracking app to record what you eat and monitor your calorie intake. Weigh yourself regularly and adjust your calorie intake as needed. If your weight stays the same, you are eating at maintenance level. If you want to gain muscle, increase your calorie intake by around 15%.

Tracking your calories can also help you understand the macronutrient composition of your diet. Macronutrients (macros) are the nutrients that provide energy: protein, carbohydrates, and fat. Each of these has a different caloric value, with protein and carbohydrates containing 4 calories per gram, and fat containing 9 calories per gram. By tracking your macros, you can ensure you are getting the right balance of nutrients to support muscle growth.

It is important to note that tracking calories and macros may not be suitable for everyone. It can be time-consuming and mentally taxing, and it may foster an unhealthy relationship with food for those with a history of disordered eating. If you are unsure, consult a registered dietitian or qualified nutritionist to help you tweak your diet.
