1. What is Weight Loss Percentage?

The weight loss percentage is a standardized way to measure weight loss that accounts for differences in starting weight. It provides a more meaningful comparison than absolute weight loss numbers, especially in competitions like "The Biggest Loser."

2. How Does the Calculator Work?

The calculator uses the weight loss percentage formula:

Where:

• Initial Weight — Your starting weight in kilograms
• Current Weight — Your 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: Percentage weight loss is a key metric in weight loss programs as it shows progress relative to starting point. It's particularly important in competitions where participants have different starting weights.

4. Using the Calculator

Tips: Enter your initial weight and current weight in kilograms. Both values must be valid (weight > 0, current weight ≤ initial weight).

5. Frequently Asked Questions (FAQ)

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

Q2: What is considered a good weight loss percentage?
A: A 5-10% weight loss is clinically significant for health benefits. In competitions, percentages vary but often exceed 20-30%.

Q3: When should I measure my weight for accuracy?
A: Measure at the same time each day (morning after bathroom use is ideal), wearing similar clothing, and using the same scale.

Q4: Can I use pounds instead of kilograms?
A: The calculator uses kg, but you can convert pounds to kg by dividing by 2.205. The percentage result would be the same regardless of units.

Q5: How often should I calculate my weight loss percentage?
A: Weekly measurements are recommended to see trends while avoiding daily fluctuations. Monthly measurements show bigger picture progress.
