1. What is the Weight Loss Formula?

The weight loss formula calculates expected weight reduction based on daily caloric deficit over a specified time period. 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)
• \( days \) — Time period (days)
• \( 7700 \) — Energy equivalent of 1 kg body weight (kcal)

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

3. Importance of Caloric Deficit

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

4. Using the Calculator

Tips: Enter your planned daily caloric deficit and the time period you want to calculate for. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Is the 7700 kcal/kg rule accurate for everyone?
A: While 7700 kcal/kg is a good average estimate, individual results may vary based on metabolism, body composition, and other factors.

Q2: What's a safe daily caloric deficit?
A: Generally, 500-1000 kcal/day deficit is recommended for safe, sustainable weight loss of 0.5-1 kg per week.

Q3: Why might actual weight loss differ from calculations?
A: Metabolic adaptations, water retention, muscle gain, and measurement inaccuracies can all affect real-world results.

Q4: How should I create a caloric deficit?
A: Through a combination of diet (eating fewer calories) and exercise (burning more calories).

Q5: Does the type of calories matter for weight loss?
A: While calorie deficit determines weight loss, nutrient quality affects health, satiety, and body composition during the process.
