Jenny Arnette, MS, RDN, CDN 

It is an absolute honor to be advancing my functional nutrition practice as a board certified Registered Dietitian at Buffalo Nutrition & Dietetics, PLLC. I am a D’Youville College graduate with a combined Bachelor and Master of Science Degree in Dietetics. I am certified in Integrative and Functional Nutrition through the credentialing board for dietitians, the Academy of Nutrition and Dietetics.

I have a deep passion for providing Medical Nutrition Therapy for pregnancy and reproductive nutrition as well as weight management and female metabolic disorders. As a functional medicine practitioner, I also focus on the prevention, management, and healing of complex chronic diseases.

While obtaining my degrees, I fulfilled over 1200 hours of dietetic internship over the course of two years, using medical nutrition therapy in a variety of areas including gastroenterology, weight management, counseling, research, acute care, critical care, and pediatrics. I had the privilege of completing my counseling and specialty rotations through the weight management clinics of both Buffalo General Hospital and Erie County Medical Center of Buffalo, New York. These combined experiences provided me the opportunity to work directly with adults suffering from various degrees of obesity as well as weight loss resistance syndrome.

I had the pleasure of completing my Pediatric nutrition rotation at John R. Oishei Children’s Hospital of Buffalo and the UBMD Pediatric Gastroenterology clinic where I worked closely with children and families in both the inpatient and outpatient settings. I routinely provided medical nutrition therapy and support to children with gastrointestinal disorders, food allergies, Diabetes Mellitus Type I and Type II, Celiac disease, as well as metabolic and genetic disorders.


My love for maternal nutrition has always been a passion, as the nutrition needs of women are unique and complex. The biological effects experienced by women throughout the lifecycle ranges drastically and requires tailored nutrition therapy for optimal outcomes. I am proud to specialize in Women’s medical nutrition therapy for pregnancy – including twins, pregnancy at 17 years of age or younger, pregnancy at 35 years or older, lactation, and accompanying concerns such as nausea, constipation, reflux, nutrient deficiencies, weight gain and favorable weight loss (post-birth). It is my pleasure that through Integrative and Functional Nutrition, I am also able to use food as medicine to nutritionally manage and improve female conditions such as PCOS, infertility, gestational diabetes, PMS, menopause, obesity, and more. 


In addition to women’s health, I have great compassion and empathy for patients who suffer from overweight, obesity, and/or weight loss resistance syndrome and metabolic disorders. I believe in a balanced approach to nutrition vs temporary or indefinite restriction. Longitudinal research has proven that fad diets may cause greater weight gain long-term whereas a balanced approach to nutrition provides sustained weight loss. I strive to provide my patients with the tools to maintain weight loss which in turn can also improve energy levels, immune function, sleep quality and mental health. 


Every patient is wonderfully unique and I recognize that even those with a similar diagnosis will have different experiences, environments and therefore needs. I seek to motivate and help implement a tailored balance to nutrition for each and every patient. I have been humbled by my medical journey and am absolutely honored with the opportunity to illuminate the path and support my patients on their own journey of preventing, managing, and healing from chronic disease.
