Important: This tracks total weight. Focus on losing fat, not muscle, for the healthiest results. Use this figure as one part of your journey.
Weight Loss Percentage Formula:
(Pounds Lost ÷ Starting Weight) × 100 = Percentage Lost
(Pounds Lost ÷ Starting Weight) × 100 = Percentage Lost
Your Weight Loss Percentage
0%
Important Note: This calculator measures total weight loss, which includes muscle mass. For a better understanding of your health progress, consider measuring body fat percentage instead.
