  • Current Weight: 75 kg
  • Goal Weight: 65 kg
  • Activity Level: Moderate (3–5 days/week exercise)
  • Weight Loss Goal: 0.5 kg per week

Results:

  • BMR: ~1,500 calories/day
  • TDEE: ~2,325 calories/day
  • Calories for Weight Loss: ~1,650 calories/day

3. What is BMR?

BMR (Basal Metabolic Rate) is the number of calories your body burns at rest.

4. What is TDEE?

TDEE (Total Daily Energy Expenditure) is your daily calorie burn including activity and exercise.

5. Why does activity level matter?

Because the more active you are, the more calories you burn, and the more you can eat while still losing weight.

6. How much weight loss per week is safe?

0.25–1 kg (0.5–2 lbs) per week is considered safe and sustainable.

7. What if I want faster results?

You can choose a higher weekly goal, but extreme calorie cuts may harm health and reduce muscle mass.

8. What happens if I eat too few calories?

Your metabolism can slow down, energy levels drop, and long-term weight loss becomes harder.

9. Can I use this tool for weight gain?

This specific calculator is for weight loss. For weight gain, you’d need a surplus-based version.
