Katherine Dittmann, MA, MS, RD

Eating Disorder Nutrition Therapist, San Francisco

Katherine Dittmann, MA, MS, RD, is a registered dietitian and nutrition therapist specializing in eating disorders, embodied self-care, and nutrition for mental health, substance use disorders, and hypermobility conditions, including hypermobile Ehlers-Danlos syndrome (hEDS). She takes a food-positive and compassion-centered approach, helping people reconnect with their bodies and develop a more easeful, sustainable relationship with eating.

Grounded in the belief that self-care is essential to recovery , her work centers on nutrition as self-care, integrating mind-body attunement, values-driven action, and the cultivation of care and kindness. In short, her job is to make eating easier.

Katherine brings nearly 20 years of experience and expertise with eating disorders across all levels of care, from adolescents to older adults. She approaches each client as a whole person first, not just a diagnosis, recognizing that eating challenges are often intertwined with anxiety, trauma, depression, and other complex health concerns. Her work is collaborative and systems-oriented, often involving coordination with a broader care team to understand how biological, psychological, and social factors interact to shape a person’s ability to nourish themselves. Katherine’s approach is inclusive, weight-neutral, non-diet, and trauma-informed with an emphasis on creating safety while building trust, capacity, and confidence around eating.

She also brings lived experience with hypermobile spectrum conditions, which informs her work with clients navigating hypermobile Ehlers-Danlos syndrome (hEDS) and related concerns. She understands that finding the right support — someone who truly gets it — can make all the difference in moving from coping to actually thriving.

Experience

Katherine works across the full spectrum of eating disorders (anorexia, bulimia, binge eating, ARFID) and is particularly adept at working with anorexia nervosa and other presentations where restrictive patterns play a central role. She is experienced in supporting more complex cases involving co-occurring medical or mental health challenges that require thoughtful, individualized nutrition care.

Across all levels of severity, she helps her clients establish structure and consistency in their eating in a way that meets them where they are while also supporting progress toward their health and recovery goals. Her approach is food-first, with the understanding that supplementation may be appropriate when clinically indicated. She is also comfortable working with clients who are prescribed GLP-1 medications as part of a comprehensive care plan, integrating these treatments thoughtfully within a braoder, recovery-oriented framework.

Sessions draw from evidence-based and integrative approaches, including CBT, DBT, ACT, IFS, Motivational Interviewing, somatic education, and mindful inquiry. For less severe or subclinical eating concerns, such as disconnection from hunger and fullness or chronic dieting, Katherine incorporates Intuitive Eating and mindful eating strategies to support a more attuned and sustainable relationship with food.

Expertise

Beyond nutrition, Katherine has special training in mind-body therapeutics, mindful self-compassion, and practical philosophy, disciplines that deepen her work at the intersection of eating, embodiment, and meaning. She is a Certified Mindful Self-Compassion (MSC) teacher and a member of APPA, the American Philosophical Practitioners’ Association.

Katherine serves as the consulting dietitian for the Mind Therapy Clinic in Corte Madera, where she collaborates with a multidisciplinary team to support clients with a range of mental health and substance use struggles. She also brings specialized interest and lived experience with hypermobile spectrum conditions, including hypermobile Ehlers-Danlos syndrome (hEDS), and understands the nuanced ways these conditions can affect digestion, energy regulation, and the ability to care for oneself consistently.

Earlier in her career, she completed her 200-hour yoga teacher training and additional training in Mindfulness Yoga Therapy for Eating Disorders, experiences that continue to inform her integrative, body-based approach.

Education

Katherine is a proud product of the California public education system. She holds a BA in French Linguistics from the University of California, Santa Barbara, an MS in Nutritional Science from San Jose State University, and an MA in Philosophy from San Francisco State University.  

Her master’s research reflects her interdisciplinary approach. Her nutrition thesis examined eating attitudes, spiritual beliefs, and body awareness in women who practice yoga (published in Eating Disorders: The Journal of Treatment and Prevention, 2009). Her philosophy master’s thesis, Self-Compassion as an Ethical Attitude in Foucault’s Care of the Self (2021), explores how cultivating self-compassion can support self-knowledge, ethical engagement, and meaningful personal change.

Once upon a time, Katherine worked as a professional chef, food writer, and yoga teacher, experiences that continue to inform her relationship-centered, embodied approach to nutrition. Outside of work, she enjoys traveling, cooking and dining, swimming, snorkeling, music, and spending time with loved ones, along with her cat, Baxter. She was born and raised in Marin County and lives in San Francisco.
