Perimenopause isn't just about estrogen. If you're eating less, working out more, and still gaining belly fat or losing muscle, the real issue may be metabolic — not hormonal.
In this episode, Vanessa sits down with Dr. Nicole Huffman to unpack what's actually happening beneath the surface in midlife: rising insulin resistance, stress-driven blood sugar swings, declining metabolic flexibility, and the silent loss of muscle that lowers resting metabolic rate.
They explore why ketosis can be a powerful tool during perimenopause — not as a rigid "diet," but as a metabolic state that stabilizes glucose, reduces inflammation, and helps restore the internal environment hormones rely on.
They also explore the powerful connection between ketosis and fertility — including insulin resistance, progesterone signaling, PCOS, and why metabolic "safety signals" matter for ovulation.
You'll also hear:
-
Why muscle preservation changes everything after 40
-
The surprising connection between stress, insulin, and progesterone
-
Why some women regain ovulation when blood sugar improves
-
How to approach keto in a flexible, woman-centered way
-
Why protein + lifting + sleep are non-negotiable
Vanessa also shares her experience using protein-sparing modified fasting (PSMF) days to drive fat loss, body recomposition and ketogenesis while protecting lean mass — and why this may be a more effective strategy for women over traditional fasting.
If you've ever said, "My body doesn't respond like it used to," this episode explains why — and what to do about it.
Dr. Nicole Huffman also shares her Radiant Woman Method, a 7-week live program designed to help women restore metabolic balance during perimenopause. Learn more about Dr. Huffman's Radiant Woman Method Here

| 0:04.5 | Hello, my friends. Welcome back to the podcast. I'm your host Vanessa. And today's episode |
| 0:10.1 | is a deep dive into one of the most misunderstood and frustrating phases of a woman's life, |
| 0:16.6 | perimenopause. And why so many women experience fat gain, muscle loss, and a slowing metabolism |
| 0:23.4 | among a myriad of other symptoms despite eating less and doing everything right. My guest today is |
| 0:29.9 | Dr. Nicole Huffman, a physician with extensive clinical experience helping women navigate |
| 0:36.4 | perimenopause, metabolic dysfunction, and even fertility |
| 0:40.1 | challenges using a root cause systems-based approach. Now, in today's episode, we go far beyond |
| 0:47.3 | calories and hormones alone. We talk about why body composition changes in midlife are not |
| 0:53.5 | explained only by estrogen decline and how |
| 0:57.0 | circulation inflammation, insulin resistance, mitochondrial function, and impaired amino acid delivery |
| 1:03.9 | to muscle play a critical role. We explore how ketosis, when implemented thoughtfully and with adequate protein, can improve |
| 1:13.0 | the metabolic environment that hormones rely on, helping to preserve lean mass, support metabolic |
| 1:18.9 | rate, and improve symptoms like cravings, fatigue, brain fog, and midlife facking. |
| 1:25.7 | We also discuss when flexibility matters, why rigid or traditional keto can |
| 1:31.2 | backfire on some women, and how a woman-centered approach can really change outcomes. |
| 1:37.0 | Finally, we get into ketosis and fertility and talk about how we can improve the metabolic environment |
| 1:44.0 | upstream of the hormonal environment, |
| 1:47.9 | including improving insulin sensitivity, ovulatory function, PCOS, and how low-carb strategies can be especially supportive. |
| 1:58.8 | Now, there's a ton of scientific literature talking about this and in today's |
| 2:03.1 | episode we provide a science forward clinically grounded conversation for women who want to understand |
| 2:09.2 | what's actually happening metabolically in perimenopause and during fertility challenges and |
