Primal Health Design

7 Key Paradigms to Reverse Biological Age

A powerful guide to living younger, longer by reconnecting with what your body already knows.

Primal Health Design is both a scientific framework and a soul-level invitation to return to the rhythms that sustain life. Drawing from his 20+ years as a neuroradiologist, his early years living among the Hadza tribe in Africa, and his ancestral lineage as a master craftsman, Dr. Kavin Mistry weaves together ancient insight and modern medicine to offer a radical new vision of health.

While modern living has helped us live longer and more comfortably, it hasn’t necessarily made us live fuller. Primal Health Design isn’t just about lifespan—it’s about healthspan: the number of years you remain healthy, vibrant, and fully alive.

Through the lens of biological age, Dr. Mistry challenges the assumptions of conventional healthcare by exploring life through the lens of the 7 Paradigms of Primal Health.

The 7 Paradigms:
Discover. Explore. Master.

These seven core paradigms form the foundation of Dr. Kavin’s approach to reversing biological age, reconnecting you with the rhythms that support long-term health, vitality, and meaning.

01

Earth

Restore balance and energy through reconnection with nature.


Our ancestors structured their lives around the rhythm of the earth its light, its temperature, its patterns. In many ways, modern life requires us to push back against these patterns rather than follow them.

This paradigm helps you reengage with nature through grounding, natural movement, light hygiene, and time outdoors. It’s about resetting your nervous system and metabolism through the environments your biology still remembers.

02

Body

Develop resilience by tuning into the body’s innate intelligence. Restore balance and energy through reconnection with nature.


Your body isn’t just a vehicle, it’s a highly intelligent system constantly communicating. With bright lights, misaligned rituals and poor sleep habits, we are not driving the vehicle on the road it is intended to follow.

Here, you’ll learn to move with intention, rest with purpose, and build strength from the inside out. Topics include mobility, breath, sleep, posture, and somatic awareness.

03.

Food

Create a nourishing relationship with what and how you eat.


Food is not just fuel. It’s information, connection, and ritual. This paradigm emphasizes eating in a way that supports hormonal balance, mitochondrial health, and metabolic flexibility.

Dr. Kavin combines ancestral eating principles with modern nutritional science to help you rediscover the power of food.

04.

Mind

Restore balance and energy through reconnection with nature.


Our ancestors structured their lives around the rhythm of the earth its light, its temperature, its patterns. In many ways, modern life requires us to push back against these patterns rather than follow them.

This paradigm helps you reengage with nature through grounding, natural movement, light hygiene, and time outdoors. It’s about resetting your nervous system and metabolism through the environments your biology still remembers.

05.

Purpose

Align your health with your reason for being.

Vitality doesn’t come from routines alone, it’s fueled by why. Drawing inspiration from the Japanese concept of Ikigai, this paradigm helps you uncover a sense of direction that infuses your life with energy and intention.

It’s about anchoring your health practices in something larger than yourself.

06.

Tribe

Build belonging and safety through meaningful connection

Modern life has eroded community and with it, a critical source of health. This paradigm focuses on social health: cultivating nourishing relationships, creating supportive environments, and embracing interdependence. Because we heal faster, grow with intention, and find meaning in our work when we feel seen, safe, and supported.

07.

Cosmos

Embrace perspective, awe, and the sacredness of life.

Think about where we come from, where we are going, and what we were meant to do in the meantime.

The final paradigm invites you to zoom out. Here, health becomes a spiritual practice, an acknowledgment of impermanence, mystery, and the bigger picture. Whether through nature, reflection, or legacy work, Cosmos helps root your vitality in meaning.
