Actionable Advice
Dr. Kiltz opens by fundamentally challenging the food pyramid and conventional dietary advice, arguing that humans are natural carnivores who have been manipulated into eating plants. He shares his personal transformation at 66 and explains why he believes the carnivore diet represents our natural eating pattern.
Dr. Kiltz explains his theory that plants contain natural defense compounds that are harmful to humans, including hormones, toxins, and inflammatory substances. He argues that many modern health problems stem from consuming these plant compounds rather than our natural diet of fatty animal products.
The discussion turns to the importance of fat for hormone production and overall health. Dr. Kiltz challenges the conventional wisdom about fat being unhealthy and explains why fatty meat should comprise the majority of human nutrition for optimal fertility and vitality.
Dr. Kiltz provides concrete steps for transitioning to carnivore eating while emphasizing that joy and mindset matter more than perfect adherence. He encourages women to take leadership in their health decisions and trust their natural instincts about what their bodies need.
“carnivore diet... It's easy. And omnivores eat plants and animals. Herbivores eat only plants. And carnivores eat only meat. And it's not lean meat they eat. The lions go for the fatty meat.”
— Dr. Robert Kiltz▶ 7:42
The carnivore diet for fertility involves eating only animal products - fatty meat, eggs, butter, bacon - while eliminating all plant foods to reduce inflammation and support hormone production.
“this label that fat is bad is actually a lie. Fat is good, both eaten and carried. If you're skinny and there's a famine, you're fertilizer.”
— Dr. Robert Kiltz▶ 8:12
Dr. Kiltz explains that fat is essential for hormone production and reduces inflammation. He argues that the belief that fat is unhealthy is a lie, and that fatty meat provides the nutrients humans evolved eating for millions of years.
“Plants contain poisons. Heroin, cocaine, marijuana, curare, nicotine... Plants make all the poisons. They make the medicinal hallucinogenic compounds. They control humanity.”
— Dr. Robert Kiltz▶ 18:55
Dr. Kiltz argues that plants contain natural toxins, hormones, and inflammatory compounds that can interfere with fertility. He points out that many drugs including birth control pills come from plants.
“go to your home, get a trash can, throw away everything that's from the plant world... Buy fatty meat, buy butter, buy cream, buy eggs, buy bacon.”
— Dr. Robert Kiltz▶ 37:59
To start carnivore for fertility, eliminate all plant foods and focus on fatty animal products like ribeye steak, bacon, eggs, butter, and cream. Dr. Kiltz recommends one meal a day with meat that's at least 50% fat.
“I've seen every story where low AMH, PCOS, metabolic syndrome, prediabetes, endometriosis, adenomyosis, suddenly, voila, I'm pregnant.”
— Dr. Robert Kiltz▶ 27:00
Dr. Kiltz reports seeing patients with PCOS, endometriosis, and other fertility conditions achieve pregnancy after adopting the carnivore diet, though he emphasizes individuals should do their own research.
“I do my one meal, one snack, maybe... I mostly go right to the fatty meat. And if I may and it's always a rib eye, personally”
— Dr. Robert Kiltz▶ 38:10
Dr. Kiltz eats one meal a day consisting primarily of fatty meat like ribeye steak, along with bacon, eggs, butter, and cream. He emphasizes the meat should be at least 50% fat content.
Dr. Kiltz's approach to transitioning to carnivore eating for fertility support
Research and Prepare
Read testimonials and watch others doing carnivore. Look at Dr. Kiltz's Instagram, Facebook, and YouTube content to see real results.
Clear Your Kitchen
Get a trash can and throw away everything from the plant world - all vegetables, fruits, grains, and processed foods.
Stock Up on Carnivore Foods
Buy fatty meat (at least 50% fat), butter, cream, eggs, and real bacon (not turkey bacon). Focus on ribeye steak as the primary meat.
Start One Meal a Day
Eat one large meal in the evening consisting of fatty meat, eggs, bacon, butter, and maybe a small amount of cheese.
Focus on Fat Content
Ensure your meat is at least 50% fat - avoid lean meats like tenderloin and chicken. Fat is the medicinal component.
Maintain the Mindset
Remember you're a lion, not a sheep. Trust your body's natural wisdom and don't let conventional nutrition advice derail you.
The carnivore diet consists of eating only fatty animal products - meat, eggs, butter, bacon - eliminating all plant foods to reduce inflammation and support fertility
Dr. Kiltz reports that at 66 years old, following carnivore for 11 years eliminated his bowel bleeding, arthritis, psoriasis, kidney stones, and migraines. He has seen patients with low AMH, PCOS, endometriosis, and adenomyosis achieve pregnancy on this approach.
Plants contain natural toxins, hormones, and antigens that create inflammation in the body, potentially interfering with fertility
Dr. Kiltz explains that heroin, cocaine, marijuana, and birth control pills all come from plants. He notes that plant compounds like lectins, oxalates, and phytates act like 'splinters' in the bloodstream, causing autoimmune-like reactions.
Fat is essential for hormone production and fertility, not the enemy conventional wisdom portrays it to be
Dr. Kiltz emphasizes that lions eat fatty meat, not lean meat, and that humans evolved eating fatty animal products for 3.5 million years. He calls the approach 'fativore' rather than carnivore to emphasize the importance of fat consumption.
One meal a day of fatty meat (at least 50% fat) can reduce inflammation and support fertility better than frequent plant-based meals
Dr. Kiltz personally follows one meal a day consisting of fatty meat like ribeye, along with bacon, eggs, butter, and cream. He reports increased energy and vitality at 66, maintaining an active lifestyle including piloting planes.
High cholesterol is not a disease but a manufactured concern designed to sell drugs that often cause more problems
Dr. Kiltz states that high cholesterol medications often create diabetes and other health issues. He references Dr. David Diamond's research on cholesterol and emphasizes that no lion needs a study to know how to eat.
Excessive exercise is counterproductive - no animal burns off calories after eating because fat storage is essential for survival
Dr. Kiltz explains that animals in nature don't exercise to burn calories after eating, as this would be 'paramount to death' during famines. He advocates for movement and activities you love rather than forced exercise.
Joy and high vibration matter more than perfect diet - you can be healthy on various diets if you prioritize happiness first
Dr. Kiltz states 'I don't care what you eat. You can eat a pure vegan, vegetarian plant based meal, and you can still be healthy and well. Come to the joy of life side first.' He emphasizes that troubles are treasures from God.
Women are natural leaders in fertility and health decisions - 'ladies lead and men meander'
Dr. Kiltz repeatedly emphasizes that 'ladies lead and men meander' and that 'mothers trump' because 'no fathers exist without mothers.' He encourages women to own their power and sexiness regardless of size, shape, or age.

Frameworks & Methods
Common Beliefs
Plants contain natural carcinogens that outweigh pesticides by a factor of 10,000 — Brussels sprouts have 136 known human carcinogens, spinach and kale have 60-80 each
Professor Bruce Ames from Berkeley published research in 1989 showing naturally occurring plant poisons outweighed pesticides by weight by 10,000 times and were orders of magnitude more likely to cause cancer than pesticides.
High insulin levels from carbohydrate consumption block the conversion of testosterone to estrogen in women's ovaries, leading to PCOS — the number one cause of infertility
Dr. Chaffee explains that women make testosterone first, then convert it to estrogen, but elevated insulin from carbs disrupts this process, causing hormonal imbalances that prevent conception.
Traditional medicine often dismisses women's health symptoms as psychological, even when serious conditions are present
Katie Keen went to her OBGYN multiple times with weight gain, fatigue, and menstrual problems. After blood tests showed 'normal' results, the doctor told her 'it's all in your head' and gave her a therapist's card, despite Katie having undiagnosed PCOS, insulin resistance, hypothyroidism, leaky gut, and severe inflammation.
Functional nutrition goes beyond general dietary advice to address root causes through personalized protocols based on individual health history and testing
Katie Keen explains functional nutrition as 'deep diving into the root causes behind what's causing the imbalances in somebody's body and then fixing those imbalances by different protocols or tailored nutritional plans and lifestyle strategies' - not just telling someone to 'go paleo' or 'eat healthy.'
