1. What Is the Weight Loss Formula?

The weight loss formula calculates how much weight you can expect to lose based on your daily calorie deficit over a period of time. It's based on the principle that a deficit of 7700 kcal equals approximately 1 kg of weight loss.

2. How Does the Calculator Work?

The calculator uses the weight loss equation:

Where:

• \( deficit \) — Daily calorie deficit (kcal/day)
• \( days \) — Duration of deficit (days)
• \( 7700 \) — Approximate kcal needed to lose 1 kg

Explanation: The equation shows the linear relationship between calorie deficit and weight loss over time.

3. Importance of Calorie Deficit

Details: Creating a consistent calorie deficit is the fundamental principle behind weight loss. This calculator helps women over 40 estimate their potential weight loss based on their planned deficit.

4. Using the Calculator

Tips: Enter your daily calorie deficit (difference between calories consumed and 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 it's a good estimate, individual results may vary due to metabolic differences, especially in women over 40.

Q2: Why focus on women over 40?
A: Metabolism changes with age, and women over 40 often need to adjust their calorie intake differently than younger women.

Q3: What's a safe calorie deficit?
A: Generally 300-500 kcal/day is safe and sustainable for most women over 40.

Q4: Does this account for plateaus?
A: No, the calculation assumes linear weight loss. In reality, weight loss may slow as you lose weight.

Q5: Should exercise calories be included?
A: Yes, your deficit should account for both reduced intake and increased exercise expenditure.
