Daily energy consumption: thresholds, calculation limits

To live, a person needs energy that he will derive from food and drink, thus compensating for his energy losses due to physical exercise and especially the maintenance of his body. ANSES (National Food Safety, Environment and Occupational Health Service) has set the following daily energy intake (AEJ) is recommended for the population in order to ensure the optimal normal functioning of the body and for the prevention of diseases. These YSS vary depending on age, gender and physical activity. Issue.

Daily energy consumption: definition

To maintain and fulfill its role, the body has energy, structural and functional needs. The National Agency for Health, Food, Environment and Occupational Safety and Health (ANSES) has identified the daily energy intake (AEJ) necessary for the various groups of the population (children, adolescents, adults, the elderly), as well as the various food ingredients (proteins, lipids, carbohydrates, vitamins, minerals and trace elements) that determine ANC (Recommended Dietary Recruitment).

To find out your energy needs, there are scientific types, especially those that take into account the ideal weight of a person who will multiply at the cost of their physical activity.


For example, for a person with average activity (cook, fisherman, etc.), we will multiply by 40 (up to 45) its ideal weight (in kg). If 70 kg is his ideal weight, he should consume 70 x 40 = 2800 Kcal per day.

Daily energy consumption: how is it characterized?

Daily energy intake is the amount of calories (or kilos) required for a person to live and cover their energy expenditure. Daily energy intake varies depending on age, gender, physical activity. AEJ may also vary depending on:

So let’s talk more about the daily energy intake estimated by scientific data by ANSES. These daily energy intake has been calculated to meet the needs of 97.5% of people in a population.

Low energy consumption limits

Energy needs vary greatly from one person to another, depending on many parameters: mainly age, gender and physical activity.

Useful information: The labeling of food products indicates for a portion or 100 g of the relevant food, what it represents in relation to the total energy consumption of the day. For example, consuming 120 g of cheeseburger provides 305 Kcal or 15.25% of AEJ for an adult woman.

Limits related to daily energy intake

Determining daily energy intake is an interesting reference point for healthcare professionals who evaluate their patients’ calorie intake. However, the YSS’s assessment is not enough to ensure optimal health and prevent diseases associated with poor nutrition.

Knowing the best daily energy intake for yourself is a good start to balancing your weight. However, it does not guarantee any shortages metals and vitamins for example. So it would be absurd to consume 2,000 Kcal a day to meet the needs of an average adult woman, just in the form of chocolate!

Knowledge of the daily energy intake that suits us is a first step in ensuring a stable weight, but this should not make us forget other equally important factors:

  • Proper proportions of food ingredients (proteins, lipids, carbohydrates, vitamins and minerals): consider the concepts of food balance with the various food families that make up our dishes.
  • The assessment of hunger and satiety signals that they will avoid compulsive eating behaviors. Daily energy intake can therefore vary from day to day.
  • The enjoyment of food: a computer does not have to constantly measure calories but the concepts of food equivalence from the same family to change its menus. (Examples: 150 grams of cooked pasta replace 1/4 baguette or 100 grams of red meat can be replaced by 2 eggs, etc.
