1. What is Percentage Weight Loss?

Percentage weight loss measures how much weight you've lost relative to your starting weight. It provides a more meaningful measure than absolute weight loss, especially when comparing individuals with different starting weights.

2. How Does the Calculator Work?

The calculator uses the percentage lost formula:

Where:

• \( initial\_weight \) — Starting weight in kilograms
• \( current\_weight \) — Current weight in kilograms

Explanation: The formula calculates what percentage of your original body weight you have lost.

3. Importance of Tracking Weight Loss

Details: Tracking percentage weight loss is important for monitoring progress in weight management programs, assessing nutritional status, and evaluating the effectiveness of diet and exercise regimens.

4. Using the Calculator

Tips: Enter both weights in kilograms (kg). For accurate results, measure weights at the same time of day under similar conditions.

5. Frequently Asked Questions (FAQ)

Q1: Why use percentage instead of absolute weight loss?
A: Percentage loss accounts for different starting weights, making it more comparable between individuals.

Q2: What is considered significant weight loss?
A: Clinically significant weight loss is typically considered to be ≥5% of initial body weight.

Q3: How often should I calculate my percentage weight loss?
A: Weekly or biweekly measurements are recommended to track trends without being overly influenced by daily fluctuations.

Q4: Can I use pounds instead of kilograms?
A: The calculator requires kg, but you can convert pounds to kg by dividing by 2.205.
