Welcome! I’m So Glad You’re Here

I’ve been immersed in the world of nutrition for over 20 years—but not just in textbooks. My journey started with me—my own body, my own struggles, and a relentless curiosity about how food could heal.

Over the years, I’ve personally explored just about every dietary approach out there: vegetarian, vegan, raw foodist, fruitarian, paleo, gluten-free, anti-candida, ketogenic, carnivore, animal-based, protein-sparing modified fasting, reverse dieting, and pro-metabolic. At the same time, I was deeply researching the anthropology of the human diet, both independently and in graduate school. What I found changed everything: our pre-agricultural ancestors were largely carnivorous—thriving on meat, raw dairy, eggs, honey, fruit, and tubers.

Today, I’ve landed in a way of eating that’s rooted in evolutionary biology, metabolic healing, and joy. I follow a nutrient-dense diet of high-quality animal foods, fruit, and less-toxic plants—and it’s brought me balance, energy, and true healing.

In addition to nutrition, I incorporate zone 2 cardio, weight lifting, and advanced vinyasa yoga into my lifestyle. Fitness and food work synergistically to rebuild a resilient, high-functioning body.

🌿 Healing My Own Body Was the Beginning

Through years of nutritional and metabolic work, I’ve personally put the following into remission:

Type 2 Diabetes
SIBO, IBS, Celiac, and chronic heartburn
Acne, anxiety, and depression
Alcoholism and disordered eating
Over 60 pounds of excess weight—gone for good

I now help clients heal without hunger or deprivation, using an ancestral, food-first, pro-metabolic approach that actually works long-term.
