1. What is Weight Loss Calculation?

The weight loss calculation estimates how much weight you can lose based on your daily caloric deficit over a specific period. It uses the principle that 1 kg of body weight is approximately equivalent to 7700 kcal.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• \( TDEE \) — Total Daily Energy Expenditure (kcal/day)
• \( deficit \) — Daily caloric deficit (kcal/day)
• \( days \) — Time period in days
• 7700 — kcal equivalent of 1 kg body weight

Explanation: The calculation shows how adjusting your daily caloric intake relative to your TDEE affects weight loss over time.

3. Importance of Caloric Deficit

Details: Creating a consistent caloric deficit is the fundamental principle behind weight loss. The calculator helps quantify the relationship between deficit and expected weight loss.

4. Using the Calculator

Tips: Enter your TDEE (use a TDEE calculator if unknown), desired daily deficit (typically 300-500 kcal/day for sustainable loss), and time period. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Is 7700 kcal really equal to 1 kg of weight?
A: This is an approximation that works well for most people, though individual results may vary based on body composition.

Q2: What's a safe daily caloric deficit?
A: 300-500 kcal/day is generally safe and sustainable. Extreme deficits can lead to muscle loss and metabolic adaptation.

Q3: Why isn't my weight loss matching the calculation?
A: Water retention, measurement errors, metabolic adaptation, and changes in activity level can all affect actual results.

Q4: Should I adjust my TDEE as I lose weight?
A: Yes, as you lose weight your TDEE decreases, so you may need to periodically recalculate your needs.

Q5: Is this calculator accurate for very low calorie diets?
A: The calculation becomes less accurate with very large deficits (>1000 kcal/day) due to metabolic changes.
