1. What Is the Weight Loss Formula?

The weight loss formula calculates estimated fat loss based on daily caloric deficit over time. It uses the scientific approximation that 1 kg of body fat contains about 7700 kcal of energy.

2. How Does the Calculator Work?

The calculator uses the weight loss equation:

Where:

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

Explanation: The equation shows how sustained caloric deficit leads to fat loss over time.

3. Importance of Caloric Deficit

Details: For women over 70, gradual weight loss (0.5-1 kg/week) through moderate caloric deficit is recommended to preserve muscle mass and bone health.

4. Using the Calculator

Tips: Enter your daily caloric deficit (typically 200-500 kcal/day for seniors) and the duration in days. The calculator will estimate your weight loss.

5. Frequently Asked Questions (FAQ)

Q1: Is 7700 kcal/kg accurate for everyone?
A: While this is a general estimate, individual variations exist based on body composition and metabolism.

Q2: Why focus on women over 70?
A: Metabolic needs change with age, and weight loss strategies should account for reduced calorie needs and muscle preservation.

Q3: What's a safe deficit for seniors?
A: Typically 200-500 kcal/day deficit is recommended to avoid muscle loss and maintain nutrition.

Q4: Does this account for metabolic adaptation?
A: No, the formula assumes constant deficit. Actual results may vary as metabolism adjusts.

Q5: Should exercise calories be included?
A: Yes, the deficit can come from both reduced intake and increased activity, but be cautious with exercise calorie estimates.
