Common questions
How do I calculate weight loss percentage?
Divide the amount lost by your starting weight, then multiply by 100. For example, losing 5kg from a 100kg starting weight is a 5% loss.
Why use percentage instead of kilograms or pounds?
Percentage loss adjusts for starting bodyweight, making it a more meaningful way to compare progress or set a sustainable target rate.
What is a realistic weekly percentage loss?
Typical sustainable ranges fall between 0.25% and 1% of bodyweight per week, depending on your goal and how aggressive you want to be.
