Stacking Years aggregates peer-reviewed research and expert consensus to rank 55 longevity interventions by their estimated impact on life expectancy. From exercise and nutrition to pharmaceuticals and supplements, every intervention is scored using a transparent methodology: 85% scientific evidence weight and 15% expert consensus weight.
The most impactful interventions include strength training, Zone 2 cardio, Mediterranean diet, sleep optimisation, and smoking cessation. Explore the full rankings, build a personalised longevity programme, and compare how leading experts like Peter Attia, Andrew Huberman, and David Sinclair approach each intervention.
Evidence scores combine scientific evidence and expert consensus. Life-expectancy gains are estimates, not guaranteed outcomes, and should not be added together.
