Heidi Moretti, MS, RD, CLT

MS · Registered Dietitian · Certified LEAP Therapist · Functional Nutritionist

Heidi is the founder of The Healthy RD and has spent over two decades bridging the gap between conventional medicine and evidence-based natural nutrition — helping people heal their gut and reclaim their health.

What Is Functional Nutrition?

Functional nutrition is a personalized, root-cause approach to health. Rather than treating symptoms in isolation, it investigates the underlying physiological imbalances that drive chronic disease — including nutrient deficiencies, gut dysbiosis, food sensitivities, inflammation, and hormonal dysfunction.

Unlike conventional dietetics, which often focuses on macronutrient targets or general guidelines, functional nutrition asks why the body is struggling and addresses those causes directly with food, lifestyle, and targeted supplementation.

Core Principles

Functional nutrition at The Healthy RD is guided by several foundational principles:

• Individuality: No two people have the same biochemistry, microbiome, or health history. Protocols are personalized, not one-size-fits-all.
• Root-cause focus: Symptoms are signals, not the problem itself. Addressing root causes — nutrient depletion, gut permeability, immune dysregulation — produces lasting results.
• Food as medicine: Whole, nutrient-dense foods are the cornerstone of every plan. Supplements support, not replace, a real-food foundation.
• Evidence-based: Every recommendation is grounded in peer-reviewed research and clinical experience.
• Collaboration: Functional nutrition works alongside, not against, your medical care team.

Areas of Focus

Heidi works with clients navigating a wide range of concerns, including:

• Gut health — IBS, IBD, SIBO, leaky gut, microbiome imbalances
• Autoimmune conditions — Hashimoto's, lupus, rheumatoid arthritis, MS
• Food sensitivities and LEAP/MRT protocol
• Fatigue, brain fog, and mitochondrial support
• Hormonal balance and thyroid health
• Metabolic health and blood sugar regulation
• Inflammation and pain management through diet

Education & Credentials

Heidi holds a Master of Science in nutritional science and is a Registered Dietitian and Certified LEAP Therapist (CLT). She continues to stay at the forefront of functional medicine research, regularly reviewing emerging science on the gut microbiome, mitochondrial health, and nutrient-gene interactions.

Her work has been published and referenced across major health and wellness platforms, and she is committed to translating complex nutritional science into practical, actionable guidance for real people.
