Daily step count where risk levels off — largely a effect.
A meta-analysis of 15 cohort studies with 47,000 adults found that dropped steeply as daily steps rose from very low levels, then flattened between 6,000 and 8,000 steps in older adults and 8,000–10,000 in younger adults.
What the researchers did
Paluch and colleagues pooled objective step-count data from 15 international cohorts, then modelled across the full range of step volumes with a median follow-up of just over 7 years.
The key finding
The dose–response was non-linear. Going from ~3,500 to 7,000 steps cut by ~50%. Above 8,000 steps in older adults (and ~10,000 in under-60s), the curve plateaued — more steps did not deliver much further benefit.
Why it matters
Most of this effect is — non-exercise activity thermogenesis. Ordinary daily movement changes your energy expenditure, , and cardiovascular risk profile far more than a single gym session.
Aim for 8,000 steps most days. You do not need 10k to get 90% of the mortality benefit.
- 1.6–2.2Daily protein intake that maximises hypertrophy.
- 7–9Nightly sleep for recovery, hormones and growth hormone release.
- 3–5Creatine monohydrate dose — no loading needed.
- 3–6Pre-training caffeine dose that reliably improves strength and endurance output.
- 25–38Daily fibre intake linked to lower all-cause mortality and a healthier gut microbiome.
- 10–20Hard working sets per muscle per week for hypertrophy.
