At age 30, Hannah McChesney was diagnosed with retinitis pigmentosa. The degenerative eye disease meant she would be blind by 50. Doctors told her there was no hope. But Hannah refused to give up.

PHCI graduate Hannah McChesney shares her story of resilience, finding Primal health and entrepreneurship.
More than 15 years later, Hannah is now thriving, and she's thrilled to share her graduate success story with us. Hannah's powerful story details how she reclaimed her health, her sight and built her flourishing health coaching practice.
Hannah McChesney's Wake-up Call
Turning 40 was Hannah’s wake-up call. Her weight was climbing. Her IBS and skin issues were getting worse. She knew it was time to take control of her health. With the help of her sister, a naturopathic doctor, Hannah found The Primal Blueprint.
Adopting an ancestral lifestyle transformed everything. She lost nearly 50 pounds. Her digestion improved. Her skin cleared. Most importantly, the progression of her eye disease slowed dramatically. “I had switched off those genes through this anti-inflammatory lifestyle,” she recalls.
Her transformation sparked a new purpose. Hannah became a “health warrior.” She shared what she learned with passion—sometimes, she laughs, to her mother’s chagrin.

Hannah McChesney reclaimed her health and life through Primal living.
Hannah McChesney Gets Certified
In 2018, Hannah took the next step by enrolling in the Primal Health Coach Institute's (PHCI's) Health Coach Certification Program. Hannah then earned her Master Coach Certification in 2020 and her Gut Health Specialist Certification in 2024. Each course sharpened Hannah's skills and helped her define how she wanted to serve others.
Carving Her Niche With Her Short-Term Coaching Programs
Through Hannah Mac Health, LLC, she now designs short-term coaching programs with long-term impact. Her 10-Day Sugar Detox and 10-Day Protein Challenge give clients quick wins. These small victories build confidence and encourage them to keep going. “It took me many years to get where I am,” Hannah says. “Helping people start their own path to health is immensely gratifying.”

Hannah McChesney is a PHCI Certified Health Coach, a Gut Microbiome Specialist, and the founder of Hannah Mac Health, LLC.
Hannah’s coaching is simple, practical, and rooted in ancestral wisdom. She draws from The Primal Blueprint, Mark’s Daily Apple, and PHCI in everything she creates. From Instagram posts (@hannahmachealth) to her coaching programs, Hannah makes health accessible. She teaches about gut health, the effects of alcohol, the power of sleep, and the benefits of time in nature.
Her work is already making an impact. In a sober women’s group, she noticed nearly everyone had worked with her. Some were past clients. Others were current or considering coaching. They shared strategies to beat sugar cravings—techniques Hannah had taught. “It felt really great,” she says. “They had adopted these changes as their own, and I was instrumental in their healthier path.”
From a diagnosis that offered no hope to building a thriving coaching business, Hannah McChesney proves what’s possible. With resilience, ancestral living, and the right training, she transformed her health and now helps others reclaim theirs.
