Good nutrition must be paired with physical activity if you want to build muscle. While weight training does help you become stronger and gain muscle, if you are not fuelling your body with the right foods, your progress will stall.
How does muscle grow?
During exercise, muscle tears and is broken down. After your workout, your body repairs and rebuilds damaged muscle, usually bigger and stronger than it was before. This process occurs during rest and is aided by the macronutrient protein (but we hope you already knew that!). Protein contains amino acids which are the building blocks for muscle growth and therefore, help to rebuild damaged muscle. Hence, high-protein foods must be included in your diet if you are to gain muscle.
You also need to ensure that you are providing your body with enough energy to build muscle. When you consume less energy than you burn, your body turns to muscle and breaks it down to use as energy, therefore, stunting your muscle growth. This means you must be consuming more calories than you are burning per day.
The amount of calories your body needs depends on a variety of factors such as weight, activity level and gender. If you are curious about how much protein your body needs for muscle growth, check out our article on how much protein do you need per day?
What to eat to gain muscle
As discussed earlier, nutrition goes hand in hand with weight training if your goal is to build muscle. You will need to eat:
Protein - to rebuild muscle
Carbohydrates - to replenish glycogen stores in the muscle and prevent fatigue
Fats - important for hormonal function which triggers more amino acids important for muscle growth
Vitamins, minerals and water - to support a healthy diet and training program
Calories - eat more calories than you burn in a day

Importance of a wholefoods diet
Although you may be trying to gain muscle and size, it doesn’t mean you should eat everything in your path. Always try to go for nutrient-rich whole foods. These will provide you with a plethora of benefits and not just extra calories to make sure you are hitting your targets. Whole foods are defined as foods that are not processed at all or are minimally processed. Eating a nutritious diet will help fuel your body so it can grow without leaving you feeling bogged down from a whole lot of preservatives, additives and sugars. The goal should be to gain muscle in a sustainable way that will leave you energised and feeling good on the inside.
