1. What is Body Fat Percentage Loss?

Body fat percentage loss measures how much of your total weight loss came from fat. Unlike simple weight measurements, it shows whether you're losing fat or just water/muscle.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Initial BF\%} \) — Your starting body fat percentage
• \( \text{Current BF\%} \) — Your current body fat percentage

Explanation: This calculation shows what percentage of your original body fat you've lost, giving a more accurate picture of your progress than weight alone.

3. Importance of Tracking Fat Loss

Details: Tracking fat loss percentage helps ensure you're losing fat rather than muscle, which is crucial for maintaining metabolism and achieving a toned appearance.

4. Using the Calculator

Tips: Enter your initial and current body fat percentages (measured through calipers, DEXA scan, or bioelectrical impedance). Values must be between 1-100% and current must be less than initial.

5. Frequently Asked Questions (FAQ)

Q1: How often should I measure body fat percentage?
A: Every 2-4 weeks is ideal, as daily fluctuations can be misleading.

Q2: What's a good fat loss percentage goal?
A: 5-10% over 3-6 months is sustainable. Rapid loss often includes muscle.

Q3: Why might my weight stay same but fat percentage drop?
A: This indicates body recomposition - losing fat while gaining muscle.

Q4: What's the most accurate measurement method?
A: DEXA scans are most accurate; calipers can work if used consistently.

Q5: Can I use this during bulking phases?
A: Yes, it helps monitor if you're gaining mostly muscle versus fat.
