The Three Keys to Health and Longevity

Whether you’re just starting out on your journey to optimal health, or seeking fresh and innovative insights, Dr. Kiltz’s three pillars to health, wellness, and longevity are here to help

  • Pillar I

    High-Fat Low-Carb Eating

    A diet centered on whole, animal-based fatty foods provides an abundance of bioavailable nutrients while reducing inflammatory sugars, plant toxins, and antinutrients

  • Pillar II

    Intermittent Fasting

    Our bodies are primed by evolution to function optimally when intermittently fasting. Benefits include cellular renewal, hormone rebalancing, reduced inflammation, neurological protection, and longevity

  • Pillar III

    Mindlfulness, Meditation & Slowing Down

    Rest, digest, and reset. Meditation and low-impact movement attunes us to the present moment, balance our nervous systems, reduce anxiety, stress, and inflammation, while boosting immune function, mental focus, and memory

Pillar I

High Fat Low Carb Diet

The first pillar of health, wellness, and longevity is the food we eat. As the father of medicine Hippocrates implored, “Let food be thy medicine.” A low-carb high-fat diet based on nutrient-dense animal foods brings our physiology into alignment with the natural ways humans evolved to eat since the dawn of our species

  • Paleo Diet

    The Paleo Diet is a popular diet focused on eliminating highly processed foods and consuming fresh meats, seafood, fruits, root vegetables, nuts, and seeds. While it’s better than the Standard American Diet, there are numerous reasons as to why this is not the optimal human diet nor is it what humans actually ate in the paleolithic period.

  • Standard Keto Diet

    A keto diet dramatically reduces carbs and increases fat intake. Keto has been shown to support the immune system,  promote fertility, maintain cardiovascular health, regulate mood, and promote bone health

  • Carnivore Diet

    A carnivore diet calls for eating 100% animal foods and eliminates all plant foods. It accords most closely with the dietary patterns humans evolved on for nearly two million years. As a type of keto, the carnivore diet enhances many of keto’s benefits while eliminating plant toxins and antinutrients

Why High Fat Low Carb

A high-fat low-carb diet based on animal foods runs contrary to outdated mainstream dietary recommendations. When we study the traditional diets of cultures that have extremely low incidences of modern diseases, a pattern emerges: Fatty, nutrient-dense animal products are front and center. A high-fat low-carb diet honors our evolutionary physiology by fueling our bodies with the most nutritious foods on earth and eliminating plant toxins and excess sugar th



The Vegetative Burden

Mainstream nutritional guidelines calling for three meals a day of plant-based foods results in consuming chronically high sugar intake along with inflammatory plant toxins and antinutrients. These foods inhibit digestive enzymes, blocks the absorption of nutrients, and clogs digestive tracts with sugars and abrasive fiber leading to chronic inflammation, constipation, and GI disorders

Pillar II

Intermittent Fasting

Ancestral Eating Patterns that Benefit Modern Life

Humans evolved on a dietary cycle of feasting on large animals and intermittently fasting between successful hunts. Over eons, the men and women whose brains and bodies functioned best in fasted states became the best at hunting food, surviving, and reproducing. We are their offspring.

As part of a modern lifestyle, intermittent fasting aligns us with our evolutionary physiology, liberates us from food addictions, and opens up time and mental space for relationship, career, and creative goals

Mind, Body, Smile

  • Mind

    Meditation, visualization, intentions, and sleep strategies help focus awareness on the things that matter most in life. Our attention is our greatest asset, and it can be used in ways that unlock the potential of our minds and bodies

  • Body

    Regular movement keeps us healthy, but excessive, high-impact exercise damages our bodies. Low-impact practices like yoga, pilates, swimming, and walking will give your body what it needs while reducing inflammatory wear-and-tear

  • Smile

    Hobbies like painting, pottery, playing music, and outdoor experiences ground us in the present moment, build confidence, and align us with our innate skills and interest

About Doctor K.

The dreams we have for our futures exist for a reason. Our commitment to ourselves to follow these dreams determines the quality of our lives. While this journey may not always be easy, I am here to help.

I believe that everyone deserves to have a family. I provide access to care for all, including those turned away from other clinics. While I am a Western trained reproductive endocrinologist, I have become a fertility specialist by integrating traditional Eastern medicine into my practice to bring together the best of both worlds.

Through the power of positive thinking, dietary changes, and a nurturing attitude toward overall health, you can achieve what you envision and desire most. By showing up for yourself, you have already begun. I’m here to show up for you too.
