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.

14CalculCalories was built because most calorie tools in French were outdated or buried in ads. Everything is free, formulas and sources (EFSA, ANSES, WHO) are published, and no account is needed — just enter your stats and get your calories, TDEE and macros.

super, I love it. There should be a full access free trial

Great utility tool! Having calorie, TDEE, BMR, and macro calculators all in one place makes daily tracking so much easier. Are you planning to add support for multiple languages alongside French?
The value proposition is clear, especially for users who want to save time on repetitive tasks. How much setup is required before someone can start getting value from it?

Having transparent formulas and cited sources (EFSA, ANSES, WHO) makes a huge difference for nutrition calculators. Great tool for anyone wanting quick, accurate calorie and macro estimations without the hassle of creating an account. Congrats on the launch! 🚀
Useful set of calculators. One thing worth double-checking: whether the TDEE and BMR formulas state which equation they use (Mifflin-St Jeor vs Harris-Benedict), since the two can differ by 5-10% and users often compare results across apps. Also consider showing the activity-multiplier step explicitly - that is where most people lose track of how the final number was reached.
Solid set of calculators - combining calorie, TDEE, BMR and macros in one place saves hopping between tools. Since it's in French, an English toggle or auto-translation would widen the audience a lot; I'd also find it useful if the macro split could adjust for training frequency or dietary preference (keto, high-protein, etc.).
Publishing the Mifflin-St Jeor formula and citing EFSA and ANSES is what makes me trust a calorie number. The per-serving recipe tool is the useful extra: could it let you paste a recipe as plain text and pick out the ingredients and amounts for you?

Does the macro calculator let users adjust their targets for different goals, such as maintaining weight or gaining muscle?
Nice work! I like the focus on making nutrition calculations simple and accessible without requiring an account. One thing I'd love to see is a more interactive experience where users can track their progress over time. That could make it even more useful beyond one-time calculations.
Great way to calculate and track calories based on build, weight, etc. Very thoughtful.
Publishing the formula and citing EFSA, ANSES and WHO is the part I'd point people to; most calculators never say which equation they use. On the sport pages, are exercise calories worked out from MET values? Those can be well off for one particular person, so a line on each page saying which method it uses and how far it can vary would fit the "sources cited" approach nicely.
