Weight Loss Formula:
| From: | To: |
Weight loss percentage is a standardized way to measure weight reduction that accounts for individual starting weights. It provides a more meaningful comparison than absolute weight loss numbers, especially when comparing progress between people of different sizes.
The calculator uses the weight loss percentage formula:
Where:
Explanation: The formula calculates the percentage of weight lost relative to the original weight, providing a standardized measure of progress.
Details: Tracking weight loss percentage helps monitor progress in weight management programs, provides motivation, and helps assess the effectiveness of diet and exercise regimens. It's particularly useful for comparing progress across different starting weights.
Tips: Enter both stone and pound values for initial and current weight. Ensure all values are positive numbers. The calculator automatically converts stone and pounds to total pounds before calculating the percentage loss.
Q1: Why use percentage instead of absolute weight loss?
A: Percentage loss provides a standardized measure that accounts for different starting weights, making progress comparisons more meaningful.
Q2: What is a healthy weight loss percentage?
A: A loss of 5-10% of initial body weight is often considered clinically significant and can lead to health improvements.
Q3: How often should I calculate weight loss percentage?
A: Weekly or bi-weekly measurements are recommended to track progress without becoming obsessive about daily fluctuations.
Q4: Does this work for weight gain calculations too?
A: The same formula can be used for weight gain by reversing the values, though the result would show percentage increase.
Q5: Are there any limitations to this calculation?
A: This calculation doesn't account for body composition changes (muscle vs. fat) or other factors like hydration levels.
