J Gulinello, MS, CNSc, FNTP  

Clinical Nutritionist • Functional Nutrition Specialist • Metabolic & Ancestral Health Educator

J is a clinical nutritionist with a master’s degree in Clinical Human Nutrition (MS), graduating with honors, and advanced certification as a Certified Nutrition Specialist Candidate (CNSc). With years of experience in functional nutrition, metabolic coaching, and lifestyle intervention, he brings a deeply evidence‑based yet ancestrally informed approach to human health.

His path into nutrition began unconventionally. After earning a degree in Music Production & Engineering from Berklee, J’s lifelong love of athletics led him to become an ISSA‑Certified Personal Trainer with a specialty in Fitness Nutrition. What started as a curiosity quickly became a professional calling: he immersed himself in the science of longevity, metabolism, and human performance — reading extensively, attending conferences, and collaborating with MDs, PhDs, and engineers.

Realizing that much of conventional nutrition was built on outdated or incomplete science, J pursued formal training through the Nutritional Therapy Association, becoming a Functional Nutritional Therapy Practitioner (FNTP). This training emphasized a bio‑individual, systems‑based approach focused on digestion, fatty acids, minerals, hydration, and blood sugar regulation — the foundations of metabolic resilience.

J later completed his master’s degree in Clinical Human Nutrition, where he worked with physicians and nurses in a New York City hospital system to improve employee health outcomes through nutrition, sleep optimization, stress physiology, and lifestyle medicine. His graduate work strengthened his expertise in clinical assessment, therapeutic nutrition, and metabolic intervention.

Today, J specializes in:

  • Low‑carbohydrate and ketogenic nutrition

  • Fasting protocols and metabolic flexibility

  • Ancestral and evolutionary nutrition

  • Performance nutrition and longevity science

  • Functional nutrition for whole‑body systems

  • Metabolic health for Mental Health

He continues to conduct independent research through an ancestral and evolutionary lens, and he leads in‑person retreats designed to reconnect people with the foundations of human health.

Outside of his clinical work, J is an avid mountain climber, endurance athlete, and lifelong student of human performance. His blend of academic rigor, functional nutrition training, and real‑world coaching experience allows him to help individuals optimize their physiology, reclaim metabolic health, and live with greater vitality.
