The most high-calorie substances that enter our body with food are fats. When digesting with a digestive enzyme one gram of fat to the final products (water and carbon dioxide), approximately 9 kilocalories of energy are released. To foods that contain a large amount of fat, include all fatty meats and fish, fat, butter and vegetable oil.
The caloric content of carbohydrates is half that of calories from fat and is approximately 4 kilocalories per gram of these substances. A large number of carbohydrates are found in various types of bread, pasta, various cereals (oat, buckwheat, rice, etc.), confectionery. You should also know that one hundred sugar is practically a pure carbohydrate, and the caloric content of one hundred grams of this product is almost 400 kilocalories.
Caloric content of proteins is approximately equal to the calorie content of carbohydrates, that is, when one digraph of protein is split in the digestive tract, about 4 kilocalories will also be released. Products with high protein content include lean meats and fish, cottage cheese, milk, kefir, cheese, eggs, caviar, beans, peas, beans.
How should we use in our daily lives information on the caloric content of proteins, fats or carbohydrates? This information is important primarily for those who want to quickly get rid of excess body weight. The fact is that the calorie content of the dishes (and therefore the whole diet) has the most direct effect on our weight. If a day we get the number of proteins, fats and carbohydrates, which in the amount of calories exceed the optimal for us indicator of the energy value of the diet, then excess calories will inevitably be stored as fatty deposits. As a consequence - the appearance of excessive body weight, flabby figure, the disappearance of interest from the opposite sex ...
So, what should you do in this situation? First of all, you need to determine the level of caloric intake you need. This indicator will depend on many factors: your age, body weight, the characteristics of professional activity, the level of physical activity in your spare time. The best option is, of course, to get advice from a specialist (a dietitian). It is believed that the caloric content of all proteins, fats and carbohydrates in the daily menu of an adult person in the sum should be approximately 3000 kilocalories (but, again, this is a strictly individual indicator).
If you are satisfied with your current weight, then you just have to make sure that your caloric intake does not exceed this figure. In this case, all the calories that will be released in your body due to the cleavage of proteins, fats and carbohydrates of food, will be fully consumed to provide physiological processes. And the excess fatty deposits will simply be nowhere to take.
But if you already have some excess body weight and therefore want to lose weight a little, you can deliberately slightly reduce the caloric content of the diet, i.e. make it not equal to 3000 kilocalories, but, say, 2900. In this case, in order to make up for the lack of 100 calories, our body will be forced to split a small amount of existing fat in its stock daily, and the mass of your body will gradually decrease.
But remember that in no case should not reduce the caloric content of the diet by reducing the protein content in it (they must receive at least 90-100 grams per day). But the amount of carbohydrates and fats consumed can be reduced slightly without much concern for your health (although you should not completely exclude them from the diet).
Thus, knowing the information about the caloric content of the main components of nutrition, which include proteins, fats and carbohydrates, you can competently plan your diet and achieve the desired state of your figure.
