1. What is the Weight Loss Time Equation?

The weight loss time equation estimates how long it will take to lose a specific amount of weight based on your daily calorie deficit. It uses the scientific fact that 1 kg of body fat contains approximately 7,700 kcal.

2. How Does the Calculator Work?

The calculator uses the weight loss time equation:

Where:

• \( weight\_loss\_kg \) — Your weight loss goal in kilograms
• \( daily\_deficit \) — Your planned daily calorie deficit in kcal
• \( 7700 \) — Approximate kcal in 1 kg of body fat

Explanation: The equation calculates how many days it will take to burn the equivalent calories of your weight loss goal at your specified daily deficit.

3. Importance of Calorie Deficit

Details: A calorie deficit is essential for weight loss. This calculator helps you plan realistic timelines for your weight loss goals based on your deficit.

4. Using the Calculator

Tips: Enter your weight loss goal in kg and your planned daily calorie deficit in kcal/day. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why 7,700 kcal per kg?
A: Research shows that 1 kg of body fat contains approximately 7,700 kcal of energy.

Q2: Is the calculation accurate for everyone?
A: It provides an estimate. Actual results may vary based on metabolic adaptation, water weight, and other factors.

Q3: What's a safe daily calorie deficit?
A: Generally 500-1000 kcal/day for 0.5-1 kg/week loss. Extreme deficits can be unhealthy.

Q4: Does this account for metabolic slowdown?
A: No, as you lose weight your BMR decreases, so you may need to adjust your deficit over time.

Q5: Should I recalculate as I progress?
A: Yes, recalculating periodically will help maintain accuracy as your weight and metabolism change.
