CALORIES are important in the diet because they are a measure of the energy that the body receives from food. Depending on your lifestyle and dietary goals, the right amount of calories in your diet can help you maintain health and a healthy weight. Calorie counting is about calculating the amount of kcal we consume during the day. We also determine how many calories you need to consume to maintain a healthy body weight. To count kcal, you can use the nutritional tables of products, smartphone applications or seek advice from a nutritionist.

The caloric value tells us how many kcal a given product or meal contains. It is usually given in units of kcal or kJ. Calories are important in the diet because eating too many kcal can lead to weight gain. In turn, eating not enough calories can lead to weight loss and lack of energy. The caloric value of the product depends on the content of protein, fat and carbohydrates. Protein and carbohydrates have about 4 kcal per gram, and fats have about 9 kcal per gram. This means that foods high in fat and sugar will have a higher caloric value. Products consisting of protein and carbohydrates less. However, it is worth remembering that not only the amount of calories, but also the quality of nutrients in the diet are important for health and well-being.
