The promotion of a healthy lifestyle influenced the fact that many began to think about the calorie content of a particular product. In order to calculate this formula, you need to refer to special tables.

Step 1
A calorie is a non-systemic unit that measures the amount of energy. It can also be equated to the amount of heat needed to heat one gram of water, for example. The final calorie value will depend on the reference water temperature.
Step 2
The calorie content of a particular food is determined by the amount of energy that will be obtained as a result of the assimilation of a particular product. Currently, researchers have already learned to experimentally determine this value. To do this, they place a certain product in a calorimeter, burn it, and measure the heat generated. Then, separately in such a chamber, the heat generated by a particular test person is measured. The resulting value is then converted into the so-called "burned" calories. Thanks to this experience, the real, that is, the physiological caloric value of a product is also recognized. These listed values can never coincide, since the metabolism in the human body is not an absolute oxidizer.
Step 3
The calorie content of one and the same product may often not correspond in different food calorie tables. For example, the European, Asian, and American values in the tables will differ. This is due to the fact that animals, vegetables and fruits were grown in different conditions, so their composition is also different. The calorie content can be influenced, in addition, by the yield of vegetables or fruits. The higher the harvest was in the year, the less carbohydrates it will contain, and accordingly, the lower the calorie content.
Step 4
In order to calculate the optimal caloric content of the diet, it is necessary to use special formulas. The numbers obtained with the help of it are always individual. They should take into account age and gender, degree of physical activity and other equally important factors of human life.
Step 5
For example, when calculating the calorie content of a product, you need to remember some rules. So, for those who want to lose weight, you need to spend more calories than you receive. The main high-calorie foods are best consumed in the first part of the day. Exercise will help you get rid of excess calories. Using the table of calorie content of foods, you can find out what energy supply the body needs.
