1. What Is the Weight Loss Formula?

The weight loss formula calculates how much weight you can lose based on your daily caloric deficit over a specific time period. It's based on the principle that 1 kg of body fat contains approximately 7,700 kcal.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• \( deficit \) — Daily caloric deficit (kcal/day)
• \( days\_in\_range \) — Duration of the deficit period (days)
• \( 7700 \) — Energy equivalent of 1 kg body fat (kcal)

Explanation: The formula calculates total caloric deficit over time and converts it to kilograms of fat loss.

3. Importance of Caloric Deficit

Details: Creating a consistent caloric deficit is the fundamental requirement for fat loss. This calculator helps estimate realistic weight loss goals over time.

4. Using the Calculator

Tips: Enter your estimated daily caloric deficit (difference between calories consumed and calories burned) and the number of days you plan to maintain this deficit.

5. Frequently Asked Questions (FAQ)

Q1: Is 7,700 kcal really equivalent to 1 kg of fat?
A: This is an approximate value. The exact energy content of body fat can vary slightly between individuals.

Q2: Why isn't my actual weight loss matching the calculation?
A: Many factors affect weight loss including water retention, muscle gain, metabolic adaptation, and measurement errors in calorie tracking.

Q3: What's a safe daily caloric deficit?
A: Generally 300-500 kcal/day for mild weight loss, or up to 1,000 kcal/day for more aggressive loss under medical supervision.

Q4: Does the type of calories matter for weight loss?
A: While calorie deficit determines weight loss, nutrient composition affects body composition, hunger levels, and overall health.

Q5: Can I use this for weight gain calculations?
A: Yes, by using a caloric surplus instead of deficit, though muscle gain rates are typically slower than fat loss rates.
