This study suggests tracking muscle-to-fat ratio, not just weight, may give a clearer picture of aging health.
Looking at adults across the UK, US, and Taiwan, researchers found the muscle-to-fat ratio matters more than raw muscle mass for healthy aging. Inflammation (measured by CRP) rose by 90% between ages 45 and 79, while the growth-related hormone IGF-1 dropped about 20%. Standard BMI-based assessments may hide early muscle decline.
