Caloric content of products is an indicator,how much energy the organism will get after the product is absorbed. The need for calories varies for each person. It is influenced by many factors - weight, height, physical costs, activity, climate, age and sex. Knowing the energy value of each product, it is easy to calculate the daily caloric value. On average, the caloric content of a woman's menu should not exceed 1800 calories per day, men - 2500, unless it's athletes and people engaged in manual labor. People who experience heavy loads need more caloric food, women up to 2500, and men up to 3000 calories a day. People who are overweight, nutritionists recommend not to reduce calorie content, but to increase the load. With a decrease in caloric content, the body will simply switch to economical energy expenditure. It will slow down the processes of digestion and assimilation of food. If after such a diet return to the previous menu, the weight will quickly recover.
Important is not only the calorie content of foods, but alsoset. One and the same energy supply can be obtained from a piece of meat and a handful of chocolates, but what will be more useful? Much can prompt the composition of the product indicated on the package. It is more difficult with ready dishes, but there are tables on which it is possible to calculate caloric content of ready-made products. What are the foods that give the greatest amount of energy when burning in the body?
Fats are the biggest producersenergy. Saturated fats, usually of animal origin, have, if not heated, a solid structure. Unsaturated - this is mainly vegetable oils. Their calorific value usually reaches 9.3 kcal per gram.
Below on the energy value of proteins, they have itequals four kcal per gram. But they have great nutritional value, because they consist of amino acids and are necessary for restoring the cells of all organs and tissues. They are contained in meat, milk and dairy products, fish, eggs.
Caloric content of food products consisting ofcarbohydrates, is equal to the energy value of proteins - four kcal per gram. They consist of simple sugars and starches, which in the body are converted into glucose. The latter is a nutrition for the cells and serves to form in the muscles and liver stores of glycogen.
If we consider products and dishes inthe same high-calorie will not always be useful. High-calorie dishes are from fast food. Hamburger from McDonald's "eats" one third of the daily diet, high in calories desserts with whipped cream, chocolate paste and nuts in chocolate. The same can be said about bacon and fat. Only 100 grams of fat will replace half the daily norm for calories. Few people know the caloric value of alcohol, although it is almost equal to the energy potential of fats and is 7.1 kcal per gram !!! Moreover, the alcohol begins to disintegrate dose absorbed and almost immediately after it enters the body, however, the process can be slowed down if eaten before a banquet something fat.
But the calorie content of vegetable productsorigin does not go into any comparison with those mentioned above. It is very low in vegetables, especially fresh ones. The vegetables that have been heat-treated are caloric, but this is because of the fats with which they were cooked. Low-calorie and unsweetened fruits, one medium Mandarin has a caloric value of 20 calories, and one hundred grams of watermelon is 12 calories. These products not only do not threaten the figure, but are also useful. Do not abuse dried fruit and candied fruits, their calorie content is high enough. As a rule, the calorie content is lower for foods that contain a lot of water. Absolutely no calories in drinks without sugar.
Therefore, you do not need to lose weight, but just correctly count the calories and then the extra pounds will not stop living.
