Julie Taube, MS, RD, LD

Nutrition and exercise have been a constant in Julie’s life. She grew up in a family of health enthusiasts and learned the value of healthy food and exercise at an early age. However, this was not her original career path. She worked in the radio industry for several years. Her desire to pursue nutrition was sparked by a personal bout with hyponatremia (an electrolyte imbalance). It occurred during the AVON Breast Cancer 3-day walk in 2000. After a frightening 24 hours in the emergency room, she recovered from the incident and realized that even though she considered herself "healthy", there was more to learn about nutrition. She knew that with this education she could help herself, her family, and other people lead healthier and happier lives.


Julie retired from radio and went on to pursue her Master’s degree in nutrition from Georgia State University. As a Registered and Licensed Dietitian, Julie counsels clients in the metro Atlanta area and gives nutrition lectures to public and private companies in Georgia. She specializes in weight loss, prenatal and postpartum nutrition, bariatrics, celiac disease, diabetes, sports nutrition, and cardiovascular wellness. She is a certified American College of Sports Medicine Health and Fitness Instructor. Julie is a marathon runner, triathlete, and indoor cycling instructor.
