The Claim
Higher muscle mass, as measured by creatinine excretion rate indexed to height squared (CERI), is independently associated with a 17% lower risk of all-cause mortality per standard deviation increase over a 10-year period in adults aged 28–75, after adjustment for protein intake, inflammation, and metabolic disease.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adults aged 28–75 with higher muscle mass, measured by creatinine excretion relative to height, have a 17% lower risk of dying from any cause over 10 years, even when accounting for protein intake, inflammation, and metabolic disease.

When protein intake is too low, the liver releases a signaling molecule that tells muscles to break down their own proteins and recycle damaged parts, causing muscle to shrink. Smaller muscles reduce the body’s ability to handle stress, fight infection, and maintain energy balance, making death from any cause more likely.
What the research says
1 studyPeople with more muscle, as estimated by how much creatinine they pee out relative to their height, were 17% less likely to die over 10 years — even if they ate the same amount of protein or had metabolic issues. Muscle mass itself was linked to living longer.
