There are 2 definitions related to calories:
· 1. The small calorie (gram calorie) – represents the energy needed to increase the temperature of 1 gram of water by 1 degree Celsius (about 4.184 Joules). The symbol of this unit is “cal”.
· 2. The large calorie (kg calorie) – represents the energy needed to increase the temperature of 1 kg of water by 1 degree Celsius (about 4.184 Kj). The symbol of this unit is Kcal and is often referred to as a Calorie (with a capital “C”).
In order to reduce body weight, dieticians recommend to reduce the intake of calories. So, in a lot of countries, producers of food products are obliged to label the nutritional value (including calories) of their products. The energy obtained from a certain food product is expressed in both Kilocalories (Kcal) and Kilojoules (Kj). In this way, everyone can calculate the daily intake of Kilocalories and can balance it with the needed quantity of Kilocalories for their life style.
In order to estimate the energy value of a product, the first step is to estimate product’s digestible constituents (fat, protein, carbohydrates, etc.). The result of this analysis is then converted into an equivalent energy value based on a standardized table of energy densities:
FOOD COMPONENT Kcal/g
1. fat 9
2. ethanol (alcohol) 7
3. proteins 4
4. carbohydrates 4
5. organic acids 3
6. polyols (sugar-free sweeteners) 2.4
These functions can be influenced in order to speed up your rate of burning calories. Some of the best solutions for this are:
2. Move more
3. Eat spicy food
4. Eat little and often
