1. What is the Weight Loss Formula?

The weight loss formula estimates how much weight you can lose based on your daily calorie 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 formula:

Where:

• \( TDEE \) — Total Daily Energy Expenditure (kcal/day)
• \( Calories \) — Actual calorie intake (kcal/day)
• \( Days \) — Duration of calorie deficit (days)
• \( 7700 \) — kcal equivalent of 1 kg body weight

Explanation: The formula calculates the total calorie deficit over time and converts it to kilograms of weight loss.

3. Importance of Calorie Deficit

Details: Creating a calorie deficit (consuming fewer calories than you burn) is the fundamental principle behind weight loss. This calculator helps quantify the relationship between calorie intake and weight loss.

4. Using the Calculator

Tips: Enter your TDEE (can be calculated separately), your actual daily calorie intake, and the number of days you plan to maintain this deficit. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Is 7700 kcal really equal to 1 kg of weight?
A: This is a general estimation. The exact number can vary slightly between individuals based on body composition.

Q2: Why isn't my weight loss linear?
A: Many factors affect weight loss including water retention, muscle gain, metabolic adaptation, and hormonal changes.

Q3: What's a safe calorie deficit?
A: Generally 300-500 kcal/day deficit is recommended for sustainable weight loss (0.5-1 kg per week).

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

Q5: Should I recalculate my TDEE as I lose weight?
A: Yes, as you lose weight your TDEE decreases because a smaller body burns fewer calories at rest and during activity.
