Calories Calculation Formula:
| From: | To: |
The calorie calculation formula estimates daily calorie intake needed for weight loss by subtracting 500 calories from your Total Daily Energy Expenditure (TDEE). This creates a calorie deficit that typically results in about 0.5kg (1lb) of weight loss per week.
The calculator uses the simple formula:
Where:
Explanation: This formula creates a moderate calorie deficit that promotes steady weight loss while maintaining energy levels and preserving muscle mass.
Details: Accurate calorie calculation is essential for effective weight management. A 500-calorie daily deficit is widely recommended by health organizations as it leads to sustainable weight loss of about 0.5kg per week without extreme hunger or nutrient deficiencies.
Tips: Enter your calculated TDEE value in kcal/day. Ensure you have an accurate TDEE measurement from a reliable calculator or professional assessment for best results.
Q1: Why subtract 500 calories specifically?
A: A 500-calorie deficit creates approximately 3500 calories deficit per week, which equals about 0.5kg (1lb) of fat loss, considered a safe and sustainable rate.
Q2: Should everyone use the same 500-calorie deficit?
A: Individual needs may vary. Those with lower TDEE may need a smaller deficit, while athletes might tolerate a larger one. Consult a healthcare professional for personalized advice.
Q3: What if I'm not losing weight with this calculation?
A: Your TDEE estimate might be inaccurate, or you may need to adjust for metabolic adaptations. Track progress and adjust as needed with professional guidance.
Q4: Is this suitable for long-term weight loss?
A: Yes, this approach is designed for sustainable long-term weight management rather than rapid short-term results.
Q5: Should I combine this with exercise?
A: Combining calorie control with regular physical activity provides the best results for weight loss and overall health improvement.
