Calorie content of foods is an indicator that indicates how much energy the body will receive after the product is absorbed. The need for calories is different for each person. It is influenced by many factors - weight, height, physical costs, activity, climate, age and gender. Knowing the energy value of each product, it is easy to calculate the daily calorie content. On average, a woman’s menu should not exceed 1800 calories per day, men should not exceed 2500 unless they are athletes and people engaged in physical labor. People experiencing heavy loads need more high-calorie foods, women under 2500, and men up to 3000 calories per day. For people suffering from overweight, nutritionists recommend not increasing calories, but increasing loads. With a decrease in calories, the body will simply switch to the economical use of energy. It will slow down the digestion and assimilation of food. If you return to the previous menu after such a diet, the weight will quickly recover.
Not only the calorie content of the products is important, but also the set. The same supply of energy can be obtained from a piece of meat and a handful of sweets, but what will be more useful? Much can tell the composition of the product indicated on the package. It is more difficult with ready meals, but there are tables by which you can calculate the calorie content of finished products. What products, when burned in the body, give the greatest amount of energy?
Fats are the largest energy producers. Saturated fats, usually of animal origin, have, if not heated, a solid structure. Unsaturated are mainly vegetable oils. Their caloric content usually reaches 9.3 kcal per gram.
Lower in protein energy, they have four kcal per gram. But they have great nutritional value, as they are composed of amino acids and are necessary for the restoration of cells of all organs and tissues. They are found in meat, milk and dairy products, fish, eggs.
The caloric content of food products consisting of carbohydrates is equal to the energy value of proteins - four kcal per gram. They consist of simple sugars and starches, which in the body turn into glucose. The latter is a food for cells and serves to form glycogen stores in muscles and liver.
If we consider the products and dishes separately, the most high-calorie ones will not always be useful. Fast foods are high in calories. A McDonald's hamburger “eats” a third of the daily ration, high-calorie desserts with whipped cream, chocolate pastes and chocolate nuts. The same can be said for bacon and bacon. Only 100 grams of fat will replace half the daily value in calories. Few people know the caloric content of alcohol, although it is almost equal to the energy potential of fats and is 7.1 kcal per gram !!! Moreover, the dose of alcohol begins to disintegrate and be absorbed almost immediately after it enters the body, however, the process can be slowed down if you eat something fatty before the banquet.
But the caloric content of plant products cannot be compared with those mentioned above. It is very low in vegetables, especially fresh ones. Heat-treated vegetables are caloric, but this is due to the fats with which they were prepared. Low-calorie and unsweetened fruits, one average tangerine has a calorie content of 20 calories, and one hundred grams of watermelon - 12 calories. These products not only do not threaten the figure, but are also useful. No need to abuse dried fruits and candied fruits, their calorie content is quite high. As a rule, calories are lower in foods containing a lot of water. There are absolutely no calories in sugar-free drinks.
Therefore, you need not to lose weight, but just correctly count calories and then extra pounds will not interfere with life.
