Every body is different. Your nutrition plan should be too. Enter your measurements and discover your personalized calorie and protein targets—based on your body, not generic averages. No sign-up. No email. Just your numbers.
Different calculators use different formulas. This one factors in your body composition (using your measurements), your activity level, AND your specific goal. Some calculators ignore body composition entirely — which is why yours might be 300 calories off. The more accurate your measurements, the more accurate your results.
It's based on established body composition formulas (the Hodgdon-Beckett Navy method and Katch-McArdle). It's accurate enough to give you a solid starting point — but remember: it's still an estimate. Your actual needs depend on metabolism, training response, and dozens of other factors. Track how you feel and adjust. That's exactly what Atunelle does inside the app — so you can see what actually works FOR YOU.
Great question. Short answer: this calculator is free and uses measurements. InBody is more expensive and uses bioelectrical impedance. Different methods, different accuracy levels, different uses — and both can be useful. We wrote a full comparison: Calculator vs. InBody Scan: Which Should You Use? (And When.)
There's no single "right" answer — different methods give different results. This calculator is calibrated for women and body composition precision. If you want the most accurate measurement, get a DEXA or InBody scan. If you want a quick, solid estimate to start with — this is it.
Nope! But if you want weekly macro adaptation based on your cycle, full meal tracking, and deeper insights — that's what Atunelle Pro does. You can use these numbers as your static targets, or upgrade to get them adapted every week. Your choice, no pressure.
Yes. This calculator is always free — no sign-up, no email required. It's our gift to women who want to understand their bodies better.
If your measurements change significantly (weight loss, muscle gain), recalculate. If you change your activity level or goal, recalculate. Otherwise, once every 3 months is reasonable. Inside Atunelle, your targets update automatically every week based on your actual data.
These numbers are your starting point. Inside Atunelle Pro, your macros adapt every week with your cycle, your training intensity, and your energy—so you're never eating the same thing all month. Get 7 days free.
