Dr. Robert Kiltz has spent decades working in reproductive medicine, but his views on what drives the fertility crisis extend well beyond the clinic. As the founder of CNY Fertility and a physician who has spent years studying the relationship between nutrition, environment, and reproductive health, he sat down with Sean Kelly on episode 1655 of the Digital Social Hour to lay out what he sees as the real — and underacknowledged — causes of declining fertility rates worldwide.
The conversation that follows is provocative and detailed, with Robert Kiltz making a case for how diet, environmental toxins, and lifestyle choices intersect with hormonal health in ways that conventional medicine rarely addresses directly. His perspective is distinctly his own, grounded in his clinical experience and personal practice, and it challenges assumptions across the spectrum of popular health advice.
About Robert Kiltz
Dr. Robert Kiltz is the founder of CNY Fertility, one of the country's largest and most accessible fertility centers, known for offering affordable IVF and reproductive services. He has worked with thousands of patients over the course of his career and has become a prominent voice on the connections between metabolic health, diet, and reproductive function.
In addition to his clinical work, Kiltz is an outspoken advocate for what he describes as animal-based nutrition and a high-fat dietary approach. His personal philosophy — which includes practices such as extended fasting and carnivore-style eating — reflects views he holds about human biology and longevity that diverge significantly from mainstream dietary guidance. These are his own perspectives and represent his interpretation of the evidence, not established medical consensus.
What Robert Kiltz and Sean Kelly Talked About

- Why he believes plant-based diets may contain compounds that interfere with reproductive health — a view he holds based on his own research and clinical experience
- How fasting, including one-meal-a-day protocols, fits into his approach to reducing inflammation and supporting metabolic health
- The difference, in his view, between vegan, vegetarian, and animal-based eating when it comes to reproductive outcomes
- How emerging technologies including robotics and AI are being applied in IVF and embryo science to improve success rates
- His argument that dietary changes may help some patients reduce dependence on expensive medical interventions
- Why regenerative farming and access to quality animal fats are, in his view, central to long-term population health
Why This Conversation Matters
Fertility is one of the most emotionally charged topics a person can face, and Dr. Robert Kiltz brings a rare combination of clinical depth and unconventional conviction to the subject. Whether or not every listener agrees with his dietary views — which he presents as his own perspective rather than settled science — his conversation with Sean Kelly on the Digital Social Hour raises questions worth sitting with for anyone thinking seriously about reproductive health, nutrition, and the state of modern medicine.
