π‘ Why Percentage Matters More Than Kilograms
Weight loss percentage = ((starting weight β current weight) / starting weight) Γ 100. Percentage is a better measure of progress than absolute kg lost because it accounts for starting size. Losing 5 kg means very different things for a 60 kg person vs a 120 kg person.
Clinical significance: 5% loss reduces risk factors for diabetes, hypertension, and cardiovascular disease. 10% loss produces major health improvements. 15%+ loss may resolve type 2 diabetes in many cases.
