Talking Points

Recent interactions between the hosts and their guests.

Functional Lab Testing, Metabolic Health & the 100-Pound Transformation | Lori Balue
Q: What is one piece of advice you would give someone starting this health journey?
Start with one step and follow reliable guidance, such as reading Wheat Belly to understand how certain foods affect the body, while gradually implementing lab-informed changes and building a supportive routine.
Functional Lab Testing, Metabolic Health & the 100-Pound Transformation | Lori Balue
Q: What role do labs and food sensitivities play in your approach to weight loss?
Labs reveal underlying dysfunctions such as gut dysbiosis, food sensitivities, and hormonal imbalances. Addressing these through targeted dietary changes, inflammation reduction, and nutrient optimization allows weight to come off more sustainably rather than relying on calorie-restriction alone.
Functional Lab Testing, Metabolic Health & the 100-Pound Transformation | Lori Balue
Q: What was the turning point that led you to pursue functional diagnostic nutrition and metabolic restoration?
A combination of personal health struggles—weight gain, depression, asthma, and chronic inflammation—paired with reading and researching until she found a pathway that connected metabolic dysfunction to overall health, which motivated her to study FDN and apply labs and nutrition strategically.
How to Build a Bulletproof Health Coaching Business | Multiple Income Streams, FDN & Time Freedom
Q: What did FDN do to change my life?
It gave back time freedom and health, enabling her to balance personal life with work, while also expanding her coaching toolkit and income streams through the FDN framework.
5 Years of Acid Reflux & Stomach Pain, Gone: The Root Cause Her Doctors Kept Missing
Q: Can you walk us through what happened in the early years and how it led you to FDN?
The breakdown started with a long health decline fueled by dietary habits, antibiotic use, and restrictive testing. After exhausting conventional options, a chance encounter with an offshoot practitioner introduced her to functional nutrition, ultimately leading to FDN and a radical shift in understanding and treating the root causes.
