Caloric content of food products is determined by the following regularity. The more basic components of nutrition (which include proteins, fats and carbohydrates) are contained in a particular product, the more caloric content it has. Therefore, it is more convenient to characterize the whole variety of foods by their caloric content on the basis of an analysis of the content of these basic nutritional components.
Protein-containing products (meat, milk, kefir, fish, cottage cheese, cheese) have approximately the average caloric value, except for those varieties of these products, which in addition to the presence of proteins are characterized by the highest content of fat - pork, fatty fish, sour cream. It should be noted that proteins are mainly used to meet the needs of plastic metabolism, that is, they are necessary for the growth of the body, its development, replacement of aging and degraded cell components. Normally, proteins are used as a "building material", and not for energy production. Therefore, it is by no means necessary to limit the consumption of proteins. The physiological rate of consumption of these substances for the body of an adult woman is approximately 90-120 grams per day (this figure increases depending on the increase in body weight and the degree of physical activity). However, the overabundance of proteins in food is also undesirable, since their surplus will turn into adipose tissue and spoil your figure.
Fats are the most caloric of all the basic components of nutrition. With digestion in the digestive tract and subsequent digestion, one gram of fat gives twice as much energy as the same amount of carbohydrates or proteins. Therefore, it is quite fair to say that foods with a high fat content spoil the figure. The most caloric fat-containing products can be called butter (both creamy and vegetable), fatty meats and fish, lard. Abusing dishes that contain fats, you are very much at risk of spoiling the figure due to the appearance of excessive body weight. Therefore, the proportion of fats in foods eaten must be strictly controlled.
Carbohydrates also refer to nutrient components that can spoil the figure pretty badly. However, such a negative effect is due not so much to the calorie content of carbohydrates (it is approximately equal to the caloric content of proteins), but rather to the amount of these substances consumed in food. The fact is that the sweetest foods always contain a lot of carbohydrates. For example, sweets and other similar sweets are practically the same solid carbohydrates. Therefore sweet tooth always very much risk to spoil a figure. Also, a large amount of carbohydrates is contained in pasta, different grades of bread, almost all croup.
Given all of the above, it becomes clear that the most high-calorie products that spoil the figure will be products containing many carbohydrates and fats at the same time. To these products can be attributed many dishes, which are a good thing in fast food restaurants. Therefore, do not seek to snack "in a hurry" - it is better to try to include daily in the menu only the most useful and not very high-calorie food, which will not spoil your figure.
