I would like to know what to measure as much as what to do.
These are treated as interchangeable and I do not think they are.
If both are acceptable I would like to know that, so I can stop thinking about it.
Is there a defensible reason to prefer one, or is this a coin flip?
The honest answer is that rapid weight loss in an older adult without resistance training is a genuine risk factor, and that the mitigation is entirely unglamorous.
Resistance training remains effective into the ninth decade; the response is slower and smaller than in younger adults but it is not absent, which is the single most useful fact in this tag.
The underlying point is that age-related loss runs at roughly one per cent of muscle mass per year after the fifth decade, accelerating later, so a superimposed deficit-related loss compounds an existing trajectory.
Grip strength predicts mortality and disability more strongly than muscle mass in longitudinal cohorts, which is the empirical basis for that reordering.
Higher protein per meal with age, because of anabolic resistance.
Aggregated, published test results and vendor ratings built from submitted batches. Methodology stated, dataset browsable, no listing fees.

Common grip-strength cut-points are below about 27 kilograms for men and 16 for women, though the thresholds vary by definition and by population reference set.
The part that matters: protein requirements are generally considered higher in older adults — often quoted at 1.2 to 1.5 g/kg for maintenance — because of anabolic resistance rather than because of increased losses.
Cut-points are population-referenced and differ between definitions, so a value near a threshold means little without the reference set.
Resistance training works at every age studied. Slower, smaller, still real.
Start with the diagnostic criteria, because the term is used loosely here and precisely in the literature, and the two usages disagree.
Sarcopenic obesity is the combination that matters in this population: adequate or high total mass with low muscle mass, which no scale detects and which a body-mass index actively conceals.
Gait speed below about 0.8 metres per second is the usual severity marker and is the measure most strongly associated with adverse outcomes.
Research-use compounds are not approved for human use, and none of them is a treatment for this.
Strength first, mass second, performance for severity. That is the definition.
Grip strength is the standard screening measure because it is cheap, repeatable and predicts outcomes better than mass does.
Appendicular skeletal muscle mass index below roughly 7.0 kg/m² in men and 5.5 kg/m² in women is the usual confirmatory threshold on DXA.
Resistance-training trials in adults over eighty demonstrate measurable strength and functional gains, which is the basis for recommending it regardless of age.
Sarcopenic obesity is invisible on a scale. Measure or you will not see it.
Answering this needs the age and the baseline, since age-related sarcopenia and deficit-related lean loss are different processes that can coexist.
The European working group definition uses low grip strength or low chair-stand performance as the entry criterion, confirms with low appendicular skeletal muscle mass adjusted for height, and grades severity by gait speed or a short physical performance battery.
The current operational definition comes from the revised European consensus, which moved strength ahead of mass as the primary criterion.
Grip strength is the cheap screening test and it is genuinely informative.
