자주 묻는 질문
CalaiFitness 계산기, 개인정보 보호, 정확성 및 사용법에 대한 자주 묻는 질문의 답변을 찾아보세요.
Are these calculators completely free?
All calculator tools on this site are available without payment, registration, or premium features. Results are calculated in the browser, so common fitness estimates remain accessible for everyday planning. Start with the calorie calculator to estimate a daily target.
Do you store my personal health data?
Calculator inputs are processed in the browser and are not sent to a server for calculation. Saved preferences, if used, remain on the device through browser storage and can be cleared in browser settings. Try the BMI calculator without creating an account.
Which TDEE formula do you use?
The TDEE estimate uses the Mifflin-St Jeor equation as its main starting point, then applies an activity multiplier. It is an estimate, not a direct measurement, so compare it with weight trends and adjust gradually. Use the TDEE calculator to calculate a baseline.
How accurate are the body fat calculators?
Tape-measure body fat estimates can be useful for tracking changes, but precision depends on consistent measuring technique, body shape, and the formula used. They should not be treated as a clinical diagnosis. Calculate an estimate with the body fat calculator using careful measurements.
Why do I need to enter my biological sex?
Many established energy equations use biological sex because average body composition and resting energy needs differ between the reference groups used to develop them. This input improves formula matching but does not define individual health. Enter the requested value in the BMR calculator for its standard equation.
Can I use these calculators offline?
After the page and its scripts have loaded, calculations can usually continue while the device is offline. Initial loading, updates, and some browser features still require an internet connection. Save the macro calculator page after opening it for convenient repeat use.
Should I eat back the calories I burn from exercise?
Avoid automatically adding exercise calories twice when the chosen activity level already includes regular training. For unusually long or intense sessions, a modest adjustment may be appropriate after monitoring recovery and body-weight trends. Build a sustainable target with the calorie deficit calculator rather than relying on one workout estimate.
What is BMI and is it accurate?
BMI compares weight with height and is useful as a broad screening measure for many adults. It does not distinguish fat from muscle, so muscular people and some other groups may receive less representative results. Check the BMI calculator alongside waist measurement and health guidance.
How much protein do I actually need?
Protein needs depend on body weight, training volume, age, total food intake, and the goal of maintenance, fat loss, or muscle gain. Spreading protein across meals can make the target easier to meet. Estimate a practical range with the protein calculator before planning meals.
Are your results medical advice?
Results are educational estimates and cannot diagnose disease, prescribe treatment, or replace individual advice from a qualified clinician or dietitian. Seek professional support for medical conditions, pregnancy, injuries, or eating concerns. Use the lean body mass calculator only as one input for general fitness planning.
Why did my TDEE change?
TDEE can change when body weight, daily movement, training volume, sleep, illness, or routine changes. As weight decreases, the energy needed for maintenance often decreases too. Recalculate periodically and compare the estimate with several weeks of data using the TDEE calculator.
What are macros?
Macros are protein, carbohydrate, and fat, the nutrients that supply most dietary energy. Their balance can support preferences, training, fullness, and overall calorie intake, but no single split suits everyone. Get a starting distribution from the macro calculator and adapt it to foods commonly available in your routine.
