A benchmark to understand your daily needs and prepare your menus. The calculation remains in your browser.
Assessing my needsFor adults aged 19 and over, according to the equations published by Health Canada. This result is not a dietary prescription.
A number of calories does not guarantee balanced menus or sufficient intakes of protein, vitamins and minerals. Do not multiply this adult profile to estimate the needs of a child.
These scenarios use the same profile and do not constitute a margin of error or four objectives to be achieved.

Rest is a separate benchmark: it is not a food target and is not used to calculate the daily need above.

Estimated energy requirement (EER) combines age, height, weight and activity category. Each category has its own equation; the calculation does not multiply resting metabolism by an activity factor.
The planning total uses the unrounded result multiplied by the duration, then is rounded to 100 kcal. The table compares the four categories without changing your other parameters.
First compose realistic menus with foods you eat and know how to prepare. Check the servings, labels, water and cooking facilities. Adjust your reserves to each person.
The level of activity may change during an evacuation or interruption of services. A scenario does not predict your actual expenditure.
This estimate does not measure your actual energy expenditure. It does not prescribe a diet or calorie deficit, or promise weight loss. Children, pregnancy, breastfeeding and particular medical needs require an appropriate method.
This interface accepts ages 19–100, weights 30–300 kg and heights 100–250 cm. These input limits do not establish clinical suitability. Ask a qualified professional for advice if the available profiles do not fit your situation.

PrépaCivile method and interface · version 1.
In the food language, "calorie" usually refers to a kilocalorie (kcal). All results of this tool are in kcal.
No. Calculate the appropriate benchmarks for each adult. For children and special situations, ask for appropriate support.
Food preparedness requires a reasonable estimate of needs and suitable menus. A change in body weight cannot reliably be predicted by simple daily subtraction.
