Calories
Calories are a type of unit used to measure energy.
In the field of nutrition the term “kilocalorie” refers to the amount of energy stored in the food that we consume to help our body work properly.
The human body is basically fed from three basic elements: carbohydrates, proteins and fat. These are the three major nutrients that allow human bodies to function properly when carrying out common and daily activities.
Carbohydrates provide four kilocalories per gram, proteins also provide four kilocalories per gram and fat provides nine calories per gram.
On the other hand, the human body needs to consume a minimum amount of nutrients in order to carry out daily tasks. Depending on the type of activities carried out by each individual, energy loss might be significantly high.
To calculate the amount of energy that your body needs, you need to know your basal metabolic rate, which refers to the amount of energy your body needs to carry out daily tasks and to maintain the body's temperature. The basal metabolic rate formula is based on 24 kilocalories per kilo. Additionally, there are some factors that can vary the rate such as age, sex, fat mass, race, climate, being pregnant, hormonal alterations or many other circumstances.
