1. What is the Weight Loss Formula?

The weight loss formula calculates expected weight reduction based on daily caloric deficit over time. It's based on the principle that 1 kg of body weight is approximately equivalent to 7700 kcal.

2. How Does the Calculator Work?

The calculator uses the weight loss equation:

Where:

• \( deficit \) — Daily caloric deficit (kcal/day)
• \( days \) — Duration of deficit (days)
• \( 7700 \) — Energy equivalent of 1 kg body weight (kcal)

Explanation: The equation shows that sustained caloric deficit leads to predictable weight loss over time.

3. Importance of Caloric Deficit

Details: Creating a caloric deficit is fundamental to weight loss. This calculator helps estimate realistic weight loss goals based on your planned deficit.

4. Using the Calculator

Tips: Enter your daily caloric deficit (difference between calories consumed and burned) and the time period you plan to maintain this deficit.

5. Frequently Asked Questions (FAQ)

Q1: Is the 7700 kcal/kg rule accurate for everyone?
A: While generally accurate, individual variations in metabolism and body composition can affect actual results.

Q2: Why isn't my weight loss matching the prediction?
A: Water retention, metabolic adaptation, and measurement inaccuracies can cause discrepancies.

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

Q4: Does the type of calories matter?
A: While weight loss depends on calories, nutrition quality affects health, hunger, and sustainability.

Q5: Should I adjust my deficit as I lose weight?
A: Yes, as your body weight decreases, your maintenance calories will also decrease.
