The balanced diet: Effective management of macronutrients and meal energy

Introduction

The introduction to the nutrition we adopt on a daily basis and the way in which we divide the diet between the various energy macronutrients and the meals of the day is a fundamental aspect of everyone's diet. It has a great impact on our overall health, our energy level, our weight and our ability to carry out daily activities. Whether you are an athlete looking to maximize performance, a person looking to maintain a healthy weight or simply feel better, understanding your diet breakdown is an essential component of achieving your health and wellness goals . The distribution of the diet essentially concerns two key factors. The first is basal calorie expenditure: this is the number of calories your body burns at rest to maintain vital functions such as breathing and circulation. The second is total energy needs: it is the total sum of calories you need during the day to support both your basal calorie expenditure and physical activities. On a nutritional level, every diet is divided into essential energy macronutrients: proteins, carbohydrates and fats. Each of these macronutrients provides a certain amount of energy, measured in calories, and the proportion in which they are consumed has a significant impact on your health, your body composition, and your energy. Finally, there is the distribution of meals throughout the day. Many of us are accustomed to three main meals - breakfast, lunch and dinner - but there may be various meal-spreading strategies that may be more effective depending on individual needs. In this article we will explore the important role that energy macronutrients have in the diet, how their correct distribution can help us better manage our weight and our general health. Additionally, we'll discuss different meal-spreading strategies to understand how the timing and frequency of meals can affect our metabolism, our energy, and the effectiveness of our diet. We'll explain how to calculate your basal calorie expenditure and how to use this information to plan an eating plan that fits your lifestyle and health goals.

Distribution of energy macronutrients

Energy macronutrient partitioning is a key concept in nutrition. As suggested by the title, energy macronutrients, i.e. proteins, lipids (or fats) and carbohydrates, are the main energy sources of our body. Their distribution in our diet helps to guarantee an appropriate caloric and nutritional intake, depending on our specific needs. Proteins, which should constitute 12% to 13% of total calories consumed, are essential in the synthesis of enzymes, hormones and tissues, including muscle ones. They are therefore important for post-workout recovery, cell renewal and support for the immune system. Lipids (or fats), which should represent 25-30% of total caloric intake, are essential for a number of functions, including the absorption of fat-soluble vitamins (such as A, D, E, K), the production of hormones and maintaining healthy skin and hair. They contain more than double the calories per gram compared to proteins and carbohydrates, and therefore can be an important source of energy especially during long-duration physical activities. Carbohydrates should make up the remaining calories in our diet. They are our body's main source of energy and support a number of vital functions, including brain and muscle activity. There are different types of carbohydrates, including sugars, starches and fibers and their choice should prefer whole grains or those with a low glycemic index, which provide more constant energy over time and promote a sense of satiety. The distribution of energy macronutrients must therefore consider not only the general recommendations, but also the specific individual needs, depending on age, sex, level of physical activity and state of health. In the presence of metabolic pathologies, such as diabetes or metabolic syndrome, the suggested percentages may need to be adequately modified, always under the supervision of a specialist. However, it is important to remember that the quality of macronutrients is just as important as their quantity. Choosing lean proteins, good quality fats (such as monounsaturated fats from vegetable oils and fish) and whole grain carbohydrates can make a difference in terms of both your health and well-being. Every food choice must be made with a view to balance, providing an appropriate mix of different foods that ensure an adequate supply of all the necessary nutrients.

Allocation of meals

The energy distribution of meals is a concept of fundamental importance in the context of a balanced diet and is closely connected to our daily caloric needs, which translates into a precise caloric division between the different meals of the day. The calorie distribution is distributed as follows: breakfast should cover 15% of our calorie needs, the mid-morning snack 5%, lunch 40%, the mid-afternoon snack another 5% and finally dinner 35% . But why this division? Let's start with breakfast, which should be the most substantial meal of the day. After a night of fasting, our body needs to receive an adequate supply of energy to better face the day. The mid-morning snack allows you to break the fast between breakfast and lunch, keeping your energy level constant. The largest meal of the day should be lunch, as it represents the time when our metabolism is most active and we are able to burn more calories. The mid-afternoon snack, similarly to the morning one, allows for a smaller drop in energy in view of dinner. Finally, dinner should cover the remaining energy needs, while not being too abundant so as not to burden the night's rest. This division, however, is not rigid and must be adapted to specific individual needs. For example, some people may need a higher calorie intake in the morning or a lower calorie intake in the evening. Furthermore, within a weight loss program, it may be useful to favor a higher calorie intake during the first part of the day, to take full advantage of the active metabolism. Always remember that the most important aspect of a diet is achieving a balance, so as to adequately nourish our body and guarantee it a constant supply of energy to better face the day. Modern lifestyles can make it difficult to follow these guidelines, but it is important to try to eat at least three meals a day, with two snacks, to keep your metabolism active and prevent sudden hunger pangs that could lead to unhealthy food choices.
