Primary Care and Lifestyle Medicine Physician
AbsoluteCare
Greenbelt, Maryland, United States
Dr. Aruna Nathan is a board-certified physician in both Internal Medicine and Lifestyle Medicine, bringing over 25 years of expertise to her practice.
Recognizing the profound connection between lifestyle choices and chronic diseases, Dr. Nathan pursued Lifestyle Medicine—a specialty focused on evidence-based therapeutic approaches to prevent, treat, and often reverse chronic conditions. These approaches emphasize improved nutrition, physical activity, practical exercise routines, sleep hygiene, and the management of stress and addictive behaviors.
As one of the nation’s first board-certified Lifestyle Medicine physicians, Dr. Nathan integrates these principles into her Internal Medicine practice. She developed a comprehensive 14-week program featuring components such as motivational interviewing, goal setting, health literacy, nutrition education, fostering connections, and delivering "food as medicine."
Dr. Nathan prioritizes addressing the root causes of disease over merely treating symptoms. Her approach incorporates nutrition education, exercise, and mindfulness while striving to minimize reliance on unnecessary medications. Currently, she serves as the Lead Physician for Lifestyle Medicine at Absolute Care, an organization dedicated to supporting some of the most vulnerable and chronically ill populations. Beyond her clinical role, she has chaired the Fitness Committee of the Maryland Wellness Council and continues to contribute as a board member of the American College of Lifestyle Medicine.
