What is a Functional Nutritionist?
A functional nutritionist is a healthcare provider who takes a personalized, science-based approach to nutrition by targeting the root of health issues instead of solely treating symptoms. Unlike conventional nutritionists who often provide one-size-fits-all meal plans, functional nutritionists evaluate your lifestyle, genetics, hormonal balance, gut health, and metabolic function to develop a plan tailored to your unique needs. The goal is to sustain the body's natural healing processes through dietary adjustments, targeted supplements, and evidence-based lifestyle interventions.

Frequently Asked Questions
Can a Functional Nutritionist Help Me Lose Weight?

Why Is It Important to Maintain a Healthy Weight?
While looking and feeling confident is a great motivator, the benefits of a healthy weight go far beyond appearance. Reaching and maintaining a healthy weight significantly reduces your risk chronic health conditions, including:
- Type 2 diabetes
- Heart disease and stroke
- Infertility and hormone imbalances
- Sleep apnea and fatigue
- Joint pain and mobility issues
- Gallbladder disease, kidney disease, and certain cancers
By improving your weight, you're also improving your body's ability to function at its best—both now and in the future.
How is a Functional Nutritionist Different from a Dietician?
Dieticians and nutritionists are trained in dietary planning and can offer valuable guidance, often based on standard guidelines like USDA guidelines. They can help with meal plans, healthy food education, and managing certain conditions through nutrition.
A functional nutritionist, however, goes beyond the basics. To create a highly personalized plan,Dr. Rabito considers your entire health picture—genetics, lifestyle, stress levels, hormone function, and more. Instead of focusing solely on symptoms or calorie counts, he identifies and addresses the root causes of your health issues using food as medicine. This whole-body, systems-based approach helps restore balance, correct deficiencies, and support long-term vitality.
