5. FAQ Section

Q: What is BMR and TDEE?
A: BMR (Basal Metabolic Rate) is the number of calories your body needs at rest to maintain basic functions. TDEE (Total Daily Energy Expenditure) is your BMR multiplied by an activity factor, representing total daily calorie needs.

Q: How accurate is the calculator?
A: The calculator uses the widely accepted Mifflin-St Jeor equation for BMR and standard activity multipliers. While accurate for most users, individual metabolic rates may vary.

Q: Can I use this on my phone?
A: Yes, the calculator is fully responsive and works on mobile devices, tablets, and desktops.

Q: What does the “Goal” dropdown do?
A: The goal adjusts your calorie target: “Maintain” keeps your TDEE, “Lose” subtracts 500 calories for weight loss, and “Gain” adds 500 calories for weight gain.

Q: Why can’t I share results on my browser?
A: The share feature uses the Web Share API, which is supported on modern browsers like Chrome and Safari. If unsupported, you can still copy results to share manually.

Q: Is my data saved?
A: No, the calculator does not store any personal data; all inputs are processed locally in your browser.
