Calcolatore Calorie

Il BMR (Basal Metabolic Rate) è il numero di calorie che il corpo brucia a riposo per mantenere le funzioni vitali (respirazione, circolazione, temperatura corporea). Viene calcolato con la formula Harris-Benedict revisionata (1990), una delle più accurate disponibili.

Il TDEE (Total Daily Energy Expenditure) è il fabbisogno calorico totale giornaliero, calcolato moltiplicando il BMR per il fattore di attività. Rappresenta le calorie necessarie per mantenere il peso attuale con il livello di attività indicato.

Per perdere peso: ridurre l'apporto calorico di 500 kcal/giorno rispetto al TDEE porta a circa 0.5 kg/settimana. Non scendere mai sotto 1200 kcal (donne) o 1500 kcal (uomini) senza supervisione medica. La qualità del cibo conta tanto quanto la quantità.

BMR is the basal metabolic rate, the calories the body burns at rest. TDEE is the total daily need, and it comes from multiplying the BMR by the factor for your activity level.

Sex, age, weight in kilograms, height in centimetres and the activity level, which runs from sedentary to extremely active. BMR and TDEE both follow from those five figures.

The calculator starts from the TDEE and shows three figures: maintenance, weight loss at 500 kcal a day less and muscle gain at 300 kcal a day more. They stay estimates, not a diet plan.

Yes, and not because we promise it: this tool runs entirely inside your browser. What you type or upload never leaves your device, so it never reaches a server of ours and there is nothing we could keep, read or lose. You can check it yourself: open the page, disconnect from the internet, and the tool keeps working.

No. There is no database behind this tool: we do not store your files, your text or your results. When you close the tab nothing is left — not here with us, because it never arrived, and not anywhere else.

We do not profile you: there is no account to create, we never ask for your email to use a tool, and we keep no profile of what you do. We are an Italian company and we work under the GDPR and the other European rules, with the privacy notice and the consent request in plain sight. One thing we say in full rather than hiding it behind a slogan: the ads on the page are Google's, and Google may use cookies to personalise them. You decide from the consent banner: if you say no the ads stay, but they are not personalised, and the tool works exactly the same.

From the ads on the page, and that is all. We do not sell your data, there is no hidden paid plan, there is no limit that eventually asks for your card, and you do not have to sign up. The ads pay for the servers and for the time we spend writing the tools: that is how we can keep them open to everyone.
