In the life of fitness enthusiasts, there are two main phases: muscle gain and reduction. Building muscle mass is a complex process that requires appropriate diet and exercise. In this text, we discuss what to consider when following a muscle-building diet.

What truly constitutes a muscle mass diet?

A muscle mass diet is an effective method of combining and utilizing nutrients in a meal plan that is intended to increase muscle mass. The main feature of this diet is the increased calorie content in meals, but keep in mind that calories should come from the best quality sources. Excess calories should be tailored to our goals and diet plan. In addition, it is important to control protein intake and fluid intake. In addition to a specific dietary regimen, a common supplementation is various types of weight gain supplements, known as gainers. Their goal is to provide excess amounts of nutrients, including vitamins and minerals. Properly used, high-quality gainers significantly accelerate muscle growth without unnecessary fat gain. Typically, their composition contains large amounts of carbohydrates, as well as smaller portions of proteins, vitamins, and minerals. The concept of a muscle mass diet involves not only the appropriate diet plan, but also remember that regular and properly designed training programs are very important. Poorly chosen exercises can often cause more harm than good. For example, an overly intense and burdensome workout can result in the burning of too many calories, which can lead to unwanted and unplanned weight loss.

Building muscle mass

Building muscle mass is a very complicated process that requires meticulous and careful preparation. The foundation for effective and efficient muscle mass building is setting a goal that we want to achieve and the type of body. It is a fundamental matter that will help us plan our future training and diet. It is important not to forget to calculate our daily caloric needs. With a properly calculated energy balance, we will be sure that we are providing our body with the appropriate amount of energy necessary to achieve our desired training. When it comes to training, the key aspect is that each muscle group should be exercised at least once a week, and ideally even twice. The frequency of training should be tailored to individual capabilities. It is also worth remembering the appropriate number of repetitions, the correct choice of load, and the speed of work. These values depend on many factors, including the length of training experience. During the building of muscle mass, an important parameter is the time under tension, in short, TUT (time under tension). It is the time during which the muscle works. We calculate it by multiplying the number of repetitions and the speed. Generally, a series should last from 20–40 seconds in the case of functional hypertrophy to even 40–70 seconds in the case of non-functional hypertrophy. Remember that training should be a stimulus for muscle development, so spending 2.5–3 hours at the gym is not necessary. A shorter, more intense training will be a better solution, and the time saved can be devoted to recovery. The key factors that influence the effectiveness of muscle mass building are rest and regeneration. During rest (i.e., sleep), there is a significant rebuilding of losses that occurred during training. The duration of sleep should be about 7–8 hours a day. Night rest ensures faster effects and significant gains.

An effective mass-building diet = a simplified mass-building diet

Many individuals believe that dieting is associated with increased costs or purchasing more expensive sources of carbohydrates. Of course, this is not true. If we are determined to achieve our set goals, limited resources should not pose a problem. It is simply a matter of using our heads and experimenting a bit. It is worth taking advantage of store prices for basic products, such as meat or various types of grains, pastas, and other sources of carbohydrates. The same products often have different prices depending on the specific store offer. Sometimes it may be beneficial to choose a local vegetable vendor or butcher shop over a large hypermarket. Another way to save money is to include inexpensive sources of essential nutrients in the diet and plan purchases – choose products with the largest weight capacity, such as grains, rice. It is also worth buying seasonal fruits and vegetables, which are a treasure trove of healthy nutrients. Frozen vegetables or fruits can also be successfully used, which are prepared at the peak of ripeness, often containing more nutrients than products stored in pantries. If we do not have enough funds for daily meals with chicken, we can include a few times a week legumes in the plan, which in combination with other ingredients of the dish will ensure that our meals are well balanced. Gainers can be replaced with homemade cocktails, and protein supplements with dairy products. We can also use nuts, flax seeds, and fatty fish as a source of unsaturated fatty acids. The problem often lies not in the limited availability of products, but in laziness. It is worth searching the internet or publications on nutrition. Sometimes the simplest solutions are right under our noses.

Nutritional plan for muscle mass construction – practical advice

Many individuals face the challenge of developing their physique, consuming too much food can lead to digestive issues and a significant loss of appetite for the next meal. There are several ways to address this situation. One approach is to increase the frequency of eating (up to 6 meals a day can be consumed) and to shorten the time between them. This change will help reduce the portions of the remaining dishes and alleviate discomfort. Another solution is to alter the taste of meals. Introducing a sweet snack in the form of a healthy dessert, an omelette, or a pancake with fruit in your plan will positively impact your appetite and significantly increase your desire for the next meal. Moreover, it is advisable to incorporate carbohydrate-rich products (or carbohydrate and protein-rich products) into your diet to make up for missing calories or when you are short on time for systematic meals. Remember that diet is a highly individual matter. There are no universal nutritional plans, so each athlete should create their own, tailored to their specific needs. If you lack the necessary knowledge, you can seek advice from a dietitian or a personal trainer.

Nutritional components and a diet for muscle development

Planning the distribution of macronutrients should be an important aspect of the nutritional plan, and each portion should provide an appropriate amount of nutrients. When promoting muscle mass growth, protein is particularly important, and consuming it in the right amounts in the diet supports muscle mass synthesis. Meals containing this component should be consumed every 3–4 hours, at least four times a day.

Average daily nutritional values

– protein: 1.2–2.3 g/kg body weight, – carbohydrates: 5–6 g/kg body weight, – fats: 25–35% of total energy consumption.
