2-1. UNDERSTANDING THE ENERGY BALANCE
All food provides calories and all calories provide energy. The human body uses this energy to
live, breathe and perform all daily activities. Generally, a man's energy needs are 5 to 10% higher
than those of a woman
calorie requirements ensure the good health of the mother and baby. This energy is measured
in kilocalories (1 kilocalorie = 1000 calories). It is recorded in Kcal but by misuse of language, we
continue to use the term «calorie» instead of «kilocalorie.».
The energy balance represents the difference between caloric intake and expenditure.

men. J Clin Invest. 1992 Sep;90(3):780-4.
2-2. MY ENERGY INTAKE
Your energy intake comes from the foods you eat. They provide calories in the form of 3 types of
macronutrients: proteins, carbohydrates and lipids.
To control your energy intake, it is important to know how many calories a food provides.
1 g protein
1 g carbohydrates
1 g fat
For example, a 154 g fillet of white fish provides 255.2 kcals.
37.7 g protein
0 g carbohydrates
11.6 g fat
2-3. MY ENERGY EXPENDITURE
You have two types of energy expenditure: basal metabolism and exercise.
Basal metabolism + exercise = energy expended per day
Basal metabolism is the minimum energy the body needs to maintain vital functions. It can vary
greatly from one individual to another. Indeed, it depends on age, sex, weight, etc. It generally
represents between 60 and 70% of total metabolism (total energy expenditure).
Exercise includes sports such as walking to work, climbing stairs or walking to take public transport
