1. What is Calorie Deficit?

A calorie deficit occurs when you consume fewer calories than your body expends. This is the fundamental principle behind weight loss, as the body taps into fat stores for energy.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• \( \text{Deficit} \) — Daily calorie deficit (kcal/day)
• \( 7 \) — Days in a week
• \( 7700 \) — Calories in 1 kg of body fat

Explanation: The formula calculates how much weight you can expect to lose per week based on your daily calorie deficit.

3. Importance of Calorie Deficit

Details: Maintaining an appropriate calorie deficit is crucial for healthy, sustainable weight loss. Too large a deficit can lead to muscle loss and metabolic slowdown.

4. Using the Calculator

Tips: Enter your daily calorie deficit in kcal/day. A deficit of 500 kcal/day is often recommended for sustainable weight loss of about 0.5 kg per week.

5. Frequently Asked Questions (FAQ)

Q1: Is 7700 kcal really equal to 1 kg of fat?
A: This is an estimate. The actual energy content of fat tissue includes some water and protein, but 7700 kcal/kg is the widely accepted conversion factor.

Q2: Why is the calculator specifically for women?
A: Women typically have different metabolic rates and body composition than men, though the basic calculation works for anyone.

Q3: Will I lose exactly this amount each week?
A: This is a theoretical calculation. Actual weight loss can vary due to water retention, muscle changes, and metabolic adaptations.

Q4: What's a safe calorie deficit?
A: Generally 250-500 kcal/day for modest weight loss. Very low calorie diets (<800 kcal/day) should be medically supervised.

Q5: Does the type of calories matter?
A: While calorie deficit determines weight loss, nutrient quality affects body composition, hunger levels, and overall health.
