Many people who want to lose unnecessary kilos are wondering how they can get the desired effect. Of course, it is important to achieve a negative energy balance. Combination of an appropriate diet and physical activity is the best solution. During the reduction, it is also important to accelerate the metabolic rate. Are including, among others, regular training sessions, as well as a well-balanced diet rich in nutrients such as protein, carbohydrates and fats. What is the role of the components in the process of reducing body fat?
Protein in the reduction diet
The protein in our body has many important functions. It is a component of enzymes, hormones and the building blocks of tissues, including muscular tissue. In the process of weight loss an important role is played by the fact that proteins increase post-prandial thermogenesis, that is, they speed up our metabolism after a meal. This increase is around 25%. The protein also has a beneficial effect, increasing the feeling of satiety. In training people wishing to lose unnecessary kilograms, it also plays an important role, adapting the body to physical exertion and regenerating muscles after training. It is important, therefore, that every meal consumed on the diet should be properly balanced and contain a source of protein.
A good source of protein in the reduction diet are products such as poultry, fish, eggs, milk and dairy products and legumes. The recommended amount of protein in the reduction diet is about 1g / kg body weight. In physically active people, this amount may be increased to 1.2 g / kg body weight. Providing the body with too small amounts of protein in the reduction diet may result in a decrease in the basic metabolism and lead to the loss of muscle tissue. The excess protein, which is excreted through the kidneys, may also be unfavorable, which may lead to their efficiency being impaired.
Carbohydrates in the reduction diet
Carbohydrates are the main source of energy in our diet. The recommended daily supply of carbohydrates varies from 50 to 60% of energy demand. Insufficient supply of carbohydrates may result in fast fatigue and weakness of the body, because glucose stored in the muscles and liver is a source of energy for the trainings. So let’s take care that they are included in a pre-workout meal.
In the reduction diet, the glycemic index (IG) of consumed products is very important. It is related to the body’s reaction to a given product. Consumption of products with a high glycemic index causes a rapid increase in the level of glucose in the blood, which may result in the storage of adipose tissue. This is because carbohydrates with high IG cause a rapid release of the hormone – insulin. An increased amount of insulin in response to consumed carbohydrates can transform unnecessary carbohydrates into fats that will be deposited in fat cells.
In the reduction diet, it is therefore worth avoiding products such as white bread, flour, rice and pasta, as well as sweets and processed products.
The sources of low and medium-weight IG carbohydrates are coarse groats such as buckwheat, barley, brown rice, whole-wheat pasta, wholemeal bread, and vegetables and most fruits. Whole-grain products as well as vegetables and fruits are also a very rich source of dietary fiber, which plays an important role in regulating the digestive tract and increasing the feeling of satiety.
Fats in the reduction diet
Fats in the reduction diet should provide about 25% of energy. It should be remembered that they are the most calorific of nutrients. However, they are necessary for the proper functioning of our body. The most beneficial for us is the elimination of saturated fatty acids – for unsaturated fatty acids. Unsaturated fatty acids (EFAs) are the building blocks of cell membranes, lower cholesterol levels in the blood, as well as increase the strength of myocardial contraction by increasing the blood flow through the coronary vessels of the heart. It is also important to provide an adequate amount of polyunsaturated omega-3 fatty acids, which have anti-inflammatory activity and, as research has shown, can increase the body’s endurance by improving oxygen metabolism.
The reduction diet is preferable
– use of vegetable oils such as olive oil, rapeseed oil or linseed oil for salads;
– inclusion of seeds, oil seeds and nuts in the diet;
– consumption of sea fish 2-3 times a week.
Remember that a healthy, balanced reduction diet ensures gradual loss of body fat. This gradation is important because it can protect us from the yo-yo effect. Fast weight-related with a sharp and significant reduction in the supply of kilocalories and nutrients, it results in a lowering of the metabolic rate and the body’s attitude to fat tissue saving and storage. It is important, therefore, that the diet is suitably suited to us in terms of calorie content and the amount of proteins, carbohydrates and fats.
