Sophia Ruan Gushee and Elizabeth McCormick discuss Dr. Robert Kiltz’s fertility diet recommendations on the Practical Nontoxic Living podcast

Boost Fertility Naturally with a High-Fat, High-Protein Diet: Lessons from Dr. Robert Kiltz (Part 1)

Jun 05, 2025

Episode 100 of the Practical Nontoxic Living Podcast

Trying to get pregnant—naturally or through IVF—can be an overwhelming journey. But what if the right diet could improve your chances?

In episode 100 of the Practical Nontoxic Living podcast, Sophia Ruan Gushée and her colleague and niece, Elizabeth McCormick, dive into a fascinating conversation inspired by Dr. Robert Kiltz’s masterclass from Ruan Living’s 40-Day Home Detox program. Dr. Kiltz is a renowned reproductive endocrinologist and founder of CNY Fertility, known for his holistic fertility protocol that emphasizes reducing inflammation and optimizing reproductive health through nutrition and lifestyle.

One key takeaway? The high-fat, high-protein, low-carb diet Dr. Kiltz recommends—which goes against much of mainstream nutrition advice. Sophia and Elizabeth unpack:

  • Why Dr. Kiltz believes animal fats and proteins support hormone balance and egg/sperm quality

  • How inflammation is linked to infertility and other chronic conditions

  • Their personal reactions to this approach and how it intersects with their detox expertise

Whether you’re preparing for IVF, trying to conceive naturally, or simply want to learn more about how nutrition influences hormones and fertility, this episode is a must-listen.
