1. What is the Weight Loss Equation?

The weight loss equation estimates daily fat loss based on your caloric deficit. It uses the scientific approximation that 7700 kcal deficit equals about 1 kg of body weight loss.

2. How Does the Calculator Work?

The calculator uses the weight loss equation:

Where:

• \( \text{deficit} \) — Daily caloric deficit (kcal/day)
• \( 7700 \) — Approximate kcal equivalent of 1 kg body fat

Explanation: The equation converts your daily calorie deficit into an estimated fat loss amount.

3. Importance of Caloric Deficit

Details: Creating a consistent caloric deficit is the fundamental requirement for fat loss. This calculator helps quantify your expected progress.

4. Using the Calculator

Tips: Enter your daily caloric deficit (intake minus expenditure). For accurate results, track your calories consistently for several days.

5. Frequently Asked Questions (FAQ)

Q1: Is 7700 kcal exactly equal to 1 kg fat loss?
A: It's an approximation. Actual fat loss varies based on water retention, glycogen stores, and individual metabolism.

Q2: Why isn't my weight loss matching the calculation?
A: Water fluctuations, muscle gain, measurement errors, and metabolic adaptation can affect short-term results.

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

Q4: Does the type of calories matter?
A: For weight loss, total calories matter most. For health and body composition, nutrient quality is crucial.

Q5: Should I recalculate as I lose weight?
A: Yes, as your basal metabolic rate decreases with weight loss, your maintenance calories will decrease.
