What is the L-N1™ Framework?
A Practical Framework for Personalized Health Decisions
Every health decision involves some uncertainty. Scientific research tells us what is likely to work for many people, but it cannot fully account for your unique health, circumstances, priorities, and goals.
The L-N1™ Framework provides a practical way to bring together three complementary sources of knowledge when making health decisions: Evidence, Expertise, and Experience.
As illustrated here, the framework places you—your goals, values, and context—at the center while bringing together these three sources of knowledge.
Scientific evidence helps us understand what tends to work. Professional expertise helps us interpret and apply that evidence safely. Our own experience helps us understand how recommendations fit our bodies and our lives.
No single source tells you everything. Together, they provide a stronger foundation for thoughtful, informed health decisions.
Why “L-N1™”?
The framework combines two important ideas: Leverage and N-of-1 Thinking.
Leverage draws from systems thinking, which recognizes that changing one part of a complex system can sometimes influence other parts. Health works much the same way. A small, well-chosen change in one area—such as sleep, movement, eating, or stress—may affect other aspects of how you feel and function.
Leverage asks: Where might a meaningful change make a difference?
N-of-1 Thinking recognizes that every person is unique. Rather than assuming that what works for others will automatically work for you, it encourages you to thoughtfully learn how evidence-based recommendations apply to your own body, circumstances, and goals.
N-of-1 Thinking asks: How does this work for me?
Together, Leverage and N-of-1 Thinking encourage you to identify meaningful opportunities for change and learn from your own experience.
A Framework for Lifelong Learning
Health is not static. As your body, circumstances, priorities, and goals change, your health decisions may need to change too.
The L-N1™ Framework is not another diet, exercise program, or health plan. It is a way of thinking—one that brings together evidence, expertise, and experience to help you make more informed health decisions over time.
The next step is learning how to put the framework into practice.
