Ashley Koff is a registered dietitian and author who spent 20 years discovering that weight and health aren't separate issues, they're connected through "weight health hormones." After her own struggles with restrictive eating despite doing everything "right," a functional medicine doctor helped her understand what was actually broken, and that was, her body's natural hormone function.

In this episode, Ashley explains why GLP-1 medications like Ozempic work, who actually needs them, and the critical foundational work required to avoid devastating rebounds. She reveals why current dietary guidelines fail women, shares her free weight health hormone assessment, cuts through the seed oil controversy, and offers practical strategies for eating healthy on any budget.

If you're confused about nutrition, frustrated that eating healthy isn't working, or curious about GLP-1 medications, this conversation provides the clarity you've been missing.

For years, functional medicine has focused on lab results and supplement protocols. Dr. Deanna Minich knows there's a deeper layer most practitioners miss. As a nutrition scientist who worked under Dr. Jeffrey Bland and educated for the Institute for Functional Medicine, she's witnessed how artificial light at night disrupts women's hormones more than almost any other factor, yet it's completely ignored.
In this episode, Dr. Minich reveals why 85% of people are Omega-3 deficient despite supplementing, how eating a rainbow of 30+ plant species weekly rebuilds your microbiome diversity, and why your skin's "photo-metabolome" produces healing compounds from sunlight that Vitamin D pills can never provide. She explains the Goldilocks principle of sun exposure, why most women only get 11-15 grams of fiber daily when they need triple that, and how stress functions as a toxin that triggers leaky gut and impairs detoxification. Dr. Minich also shares why women's heightened sensitivity isn't a weakness but a powerful gift for intuition and healing.
If you're tired of functional medicine that stops at labs and supplements, this conversation offers a comprehensive framework integrating circadian optimization, creative expression, gut diversity, and the spiritual aspects of women's health that determine true longevity.Guest’s socials + website
