If you already know and cover your calorie requirements for muscle building, the second step is to think about the composition of the individual macronutrients; proteins, carbohydrates and fats in a meal plan. The nutrients most suitable for muscle building are high-quality protein sources from low-fat meat (chicken, turkey, beef), eggs, dairy products, red lentils, kidney beans, chickpeas, soy, buckwheat and quinoa. They are rich in essential amino acids and thus provide the body with the required building blocks for muscle building. The sufficient supply of carbohydrates is especially important within muscle building as it is what maintains the constant and progressive weight increase in weight training. If the body doesn’t receive energy from oatmeal, whole grain products or potatoes, this often has a negative impact on training performance. Simple carbohydrates such as bananas, rice cakes or gummy bears can be consumed to create an anabolic environment for muscle building through high insulin levels. Positive side effect: The recovery of the body improves and glycogen stores in muscles are replenished faster.
