“Bone broth isn’t just broth. And it isn’t just soup. It’s concentrated healing. This broth is nutrient-rich “liquid gold,” one of the world’s oldest and most powerful medicinal foods.”

Dr. Kellyann Petrucci came to realize the ancient power of collagen and bone broth to heal the gut and slow aging while studying biological medicine at the Marion Foundation and Paracelsus Clinic, Switzerland. By focusing her practice on a lifestyle that stops and reverses inflammation, Dr. Kellyann is able to help patients and readers reduce dangerous belly fat to become slimmer, younger, and healthier.

Bone broth supports health at the cellular level. When you revitalize your cells, you can:

  • reverse signs of aging
  • lose weight
  • regain your energy
  • conquer metabolic syndrome and diabetes
  • get rid of headaches
  • overcome bloating, diarrhea, and constipation
  • support autoimmune conditions
  • reduce the chronic inflammation that’s linked to heart disease, cancer, and other “aging” diseases

Jen's Story

“I was extremely ill. I had gained over 60 pounds due to meds, thyroid problems and inactivity. I was suffering from uncontrolled Grave’s Disease, hyperthyroidism and adrenal fatigue. I was sick and miserable all the time. My doctor recommended this plan and it saved my life. I went from 214 pounds to 160. My thyroid levels are stable without meds, all my adrenal symptoms are gone. I feel like my old self again.”

Mary's Story

“I lost 60 pounds total—and have kept it off for more than one year. I love the eating plan and whenever I start to get out of control I just buckle down and make sure I am doing 80/20 and include 2 fasting days a week. This is the longest I’ve gone without regaining lost weight. I am currently 64 years old.”

My Philosophy:

  • I treat the whole patient—not just the symptoms.
  • Getting healthy is a partnership between my patient and me.
  • I’ll take as much time as you need.
  • I’ll answer all your questions and explain all your treatment options.

Together, our goal is to get you:

  • Feeling younger, healthier, happier, and more alive.
  • Moving beyond trends and fads to discover a way of life that works for your body and mind.

Above all, I focus on techniques for transforming my patients naturally. As a board-certified naturopathic doctor, I offer alternatives to pharmaceutical pills and surgeries. My prescriptions range from anti-aging foods and bio-identical hormones to nutritional supplements and stress-reducing meditation.

The foundation for a sexy, healthy body and strong mind starts with clean cells. Once you reach your maximum cellular health, you will achieve the transformation you’re seeking. In fact, I’m living proof.
