Diet, Inflammation, and the Environment We Live In
Why are so many people struggling to conceive?
Not quietly. Not rarely. But everywhere.
Infertility is no longer an outlier conversation.
It’s becoming a shared one.
In this episode of Never Been Sicker, I sit down with Dr. Robert Kiltz to unpack a question many people are already asking… even if they’re not saying it out loud.
What’s really driving this trend?
Who You’re Listening To: Dr. Robert Kiltz
Dr. Robert Kiltz is a fertility specialist and the Founder of CNY Fertility, one of the largest fertility practices in the United States.
His work sits at the intersection of:
• Reproductive endocrinology • Metabolic health • Lifestyle medicine • Patient-centered care
In short:
He helps families grow while challenging conventional narratives around fertility and health.
And he’s not afraid to question long-standing assumptions about diet, inflammation, and modern living.
Infertility Is Rising. But Why?
Dr. Kiltz has spent decades working directly with couples navigating fertility challenges.
His observation is simple.
Infertility is increasing.
And in his view, this is not random.
He connects this rise to patterns we now see across nearly every chronic health conversation:
- Inflammation.
- Metabolic dysfunction.
- And the cumulative burden of modern lifestyles.
Conditions like endometriosis, PCOS, diminished ovarian reserve, and early menopause are becoming increasingly common.
Which raises an uncomfortable but necessary question:
If these conditions are common…Why are we still treating them like isolated events?
The Inflammation Conversation Most People Miss
Fertility does not operate in isolation from the rest of the body.
Hormones do not function independently of metabolism.
Reproductive health does not exist outside immune signaling.
Dr. Kiltz frames infertility through a lens often overlooked:
Chronic inflammation.
Not as a vague concept. But as a physiological driver that can influence:
- Hormone regulation
- Cellular signaling
- Ovarian function
- Systemic resilience
Whether someone agrees with his exact nutritional philosophy or not, the broader biological truth remains steady:
What stresses the body affects its ability to function optimally.
Reproduction included.
Modern Diet Patterns and Metabolic Stress
Dr. Kiltz is well known for his outspoken views on diet, fasting, and animal-based eating.
He challenges decades of mainstream dietary advice, particularly frequent eating patterns and low-fat recommendations.
His core argument centers on metabolic load.
- Constant digestion.
- Elevated insulin.
- Persistent inflammatory signaling.
While his dietary framework may be controversial for some, the underlying principle reflects a widely accepted scientific reality:
Metabolic dysfunction and inflammation are deeply intertwined.
And fertility does not operate outside that biology.
Environment: The Fertility Variable Few People Consider
Midway through the episode, the conversation shifts toward something rarely discussed in fertility care.
Indoor environments.
We now spend roughly 90 percent of our lives indoors.
- Modern homes are tightly sealed.
- Buildings contain thousands of materials, chemicals, particles, and biological contaminants interacting continuously.
- Moisture.
- Microbes.
- Off-gassing compounds.
- Ventilation systems that can redistribute exposures.
Dr. Kiltz acknowledges something critical:
What we breathe, drink, and eat are foundational inputs into health.
If the body is already navigating inflammatory stress from diet, metabolism, and chronic pressure… Environmental exposures may become part of the equation.
Not the only factor.
But a meaningful one.
Mindset, Stress, and Fertility
One of the most human moments of the episode comes near the end.
What can someone struggling with infertility do right now? Dr. Kiltz emphasizes mindset.
Visualization.
Interrupting fear cycles.
Because chronic stress is not just emotional.
It is hormonal.
Physiological.
Systemic.
Stress hormones directly influence reproductive hormones. Meaning mindset is not abstract philosophy.
It is biology.
Control the Controllables
Infertility is complex. There is no single cause. No universal protocol.
But this conversation lands on something deeply empowering:
Agency.
You may not control everything. But you can influence:
- Your diet
- Your indoor environment
- Your stress load
- Your exposures
- Your daily habits
Small shifts. Compounding effects. Reduced physiological burden.
Final Word
If fertility feels like a growing conversation around you… You’re not imagining things.
If you’ve been told “everything looks normal” but something still feels unresolved…
That experience is more common than you think.
Better questions matter.
Deeper investigation matters.
Inputs matter.
Because reproduction is not just a medical topic. It is a human one.
And modern health conversations must start reflecting that reality.
