1. What is the Fat Loss Equation?

The fat loss equation calculates how much body fat you can expect to lose based on your daily caloric deficit over a period of time. It's based on the principle that 1 kg of body fat contains approximately 7,700 kcal.

2. How Does the Calculator Work?

The calculator uses the fat loss equation:

Where:

• \( deficit \) — Daily caloric deficit (kcal/day)
• \( days \) — Duration of deficit (days)
• \( 7700 \) — kcal per kg of body fat

Explanation: The equation accounts for the energy balance principle where consistent caloric deficit leads to fat loss over time.

3. Importance of Caloric Deficit

Details: For men over 60, maintaining an appropriate caloric deficit is crucial for healthy fat loss while preserving muscle mass and metabolic health.

4. Using the Calculator

Tips: Enter your daily caloric deficit (typically 300-500 kcal/day for sustainable loss) and the number of days you plan to maintain this deficit.

5. Frequently Asked Questions (FAQ)

Q1: Why 7,700 kcal per kg?
A: This is the estimated energy content of 1 kg of human body fat, accounting for adipose tissue composition.

Q2: Is this different for men over 60?
A: The equation is the same, but men over 60 should consider slower loss (200-300 kcal deficit) to preserve muscle.

Q3: Why might actual results vary?
A: Metabolic adaptation, water retention, and changes in activity can affect actual fat loss.

Q4: How accurate is this for long-term predictions?
A: Less accurate over long periods as metabolism adjusts. Best for 4-12 week projections.

Q5: Should exercise be included in the deficit?
A: Yes, the total deficit (diet + exercise) should be used for calculations.
