Is Fasting a Female Longevity Lever? CGMs, Berberine & Metabolic Health
The Luminescence Podcast with Schuyler GrantShow Notes
Metabolic health isn't really about weight, Schuyler Grant, Dr. Robin Berzin, and Dr. Mary Pardee argue — it's the single biggest lever available for healthspan, driving everything from brain function to bone health to the "four horsemen" of heart disease, cancer, and dementia.
So they zero in on the two protocols Schuyler calls the most provocative in the whole metabolic conversation: intermittent fasting and continuous glucose monitors.
They discuss:
Why intermittent fasting only works if it actually reduces total daily calories — and why treating it as a magic fix on top of overeating doesn't hold up
Who should avoid fasting protocols entirely, including anyone actively trying to conceive
Dr. Berzin's own CGM story — how an incidental discovery while wearing one turned out to be genuinely life-changing, and where Dr. Pardee remains skeptical for healthy women
A rapid-fire round: Zone 2 training (hard yes), berberine (a qualified yes — effective, but not first choice), ketogenic protocols long-term (BS), continuous protein feeding (BS — total daily protein matters more), glucose-disposal stacks like cinnamon and apple cider vinegar (BS), eliminating seed oils as a metabolic hack (BS), and methylene blue (BS)
Why the panel keeps landing back on the same unglamorous answer: build and keep lean muscle mass
For any woman drowning in metabolic protocol content who wants to know which two are actually worth trying.

Viagra was approved in 1998. It took another two decades before women's sexual health started being treated as a physiological issue instead of a mood problem — and most women still don't know there are three real prescription options for low desire.
Estrogen receptors are in nearly every organ in your body, so when estrogen drops, your whole body feels it. OB/GYN and menopause expert Dr. Mary Claire Haver explains what that means for your bones, muscle, heart, brain, and belly fat. Recorded live at the Luminescence event in Texas.
Women lose up to 20% of their bone density during perimenopause, often silently, until a fracture makes it impossible to ignore.
55% of women say they've felt gaslit by a doctor. 80% delay care rather than walk into an appointment where they know they won't be heard.
Menopause is usually talked about in terms of hot flashes and mood swings. But beneath those symptoms are silent, system-wide changes and one of the most important ones happens in the heart.
