1. What is the Weight Loss Formula?

The weight loss formula calculates how much weight you can expect to lose based on your daily caloric deficit over a period of 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/kg)

Explanation: The equation shows that weight loss is proportional to both the size of your daily caloric deficit and the duration of that deficit.

3. Importance of Caloric Deficit

Details: Creating a caloric deficit is the fundamental requirement for weight loss. This calculator helps quantify the relationship between deficit, time, and expected weight loss.

4. Using the Calculator

Tips: Enter your daily caloric deficit (difference between calories consumed and calories burned) and the number of days you plan to maintain this deficit. 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, individual results may vary based on body composition and metabolic factors.

Q2: Why isn't my weight loss matching the calculation?
A: Water retention, changes in activity level, metabolic adaptation, and measurement errors can all affect actual results.

Q3: Can I use this for weight gain calculations?
A: Yes, by using a caloric surplus instead of deficit, the same formula applies for estimating weight gain.

Q4: What's a safe caloric deficit?
A: Generally 300-500 kcal/day deficit is safe for most people, or up to 20% of total daily energy expenditure.

Q5: Does the type of calories matter for weight loss?
A: For pure weight loss, total calories matter most, but nutrient composition affects satiety, health, and body composition.
