CalculCalories

CalculCalories is a free, French-language site of nutrition calculators. Enter your age, sex, height, weight, activity level and goal (lose, maintain or gain) to estimate your basal metabolism, daily energy expenditure (TDEE), calorie target, protein range and macro split, using the Mifflin–St Jeor formula. Other tools cover BMI, calorie deficit, protein needs and the nutrition of your own recipes, per serving. It also has food pages, sport pages (walking, running, cycling, weight training) and guides. Formulas are published and sources cited (EFSA, ANSES, WHO). No account required; results are estimates, not medical advice.
