The Rhitrition Clinic in Marylebone
Located at 10 Harley Street, one of London’s most prestigious medical addresses, the Rhitrition clinic embodies professionalism and care. The clinic’s environment is warm, inclusive, and designed to provide a confidential, supportive space for every client.
The Rhitrition team consists of registered dietitians, nutritionists, and an in-house psychologist, all working collaboratively to ensure that clients receive personalised, evidence-based guidance.

Core Areas of Expertise
1. Eating Disorders and Disordered Eating
Rhitrition is renowned for its sensitive and structured approach to treating eating disorders. By combining nutritional therapy with psychological support, the team helps clients restore a balanced relationship with food and body image. This service is particularly beneficial for individuals recovering from anorexia, bulimia, binge eating disorder, or chronic dieting cycles.
2. Gut Health
Digestive health is a cornerstone of overall well-being. Rhitrition provides tailored guidance on improving gut function, reducing bloating, and managing conditions like irritable bowel syndrome (IBS). The clinic’s gut-focused nutrition plans are grounded in the latest research, helping clients enhance their microbiome health and energy levels.
3. Weight Management
Unlike traditional dieting programmes, Rhitrition promotes evidence-based weight management rooted in sustainable lifestyle change rather than restriction. Their team works to educate clients about balanced eating, portion control, and mindful habits that promote long-term results.
4. Sports Nutrition
Athletes and active individuals turn to Rhitrition for expert advice on performance nutrition. The clinic provides bespoke plans designed to improve endurance, recovery, and strength, ensuring clients fuel their bodies effectively for optimal performance.
5. Fertility, Pre and Post-Natal Nutrition
Nutrition plays a key role in reproductive health. Rhitrition offers specialist guidance for individuals and couples looking to optimise fertility, as well as tailored dietary plans for expectant and new mothers to support both maternal and infant health.
6. Family and Child Nutrition
Healthy eating habits start early. Rhitrition helps families navigate food challenges, encouraging positive mealtime behaviours and balanced nutrition for children of all ages.
7. Intuitive Eating
One of Rhitrition’s core philosophies is intuitive eating — the practice of listening to one’s body cues to develop a natural, guilt-free relationship with food. This method empowers individuals to eat according to hunger, satisfaction, and emotional awareness, rather than external diet rules.
Rhitrition’s Evidence-Based Approach
Rhitrition stands out for its scientific integrity and rejection of quick fixes or fad diets. Every consultation, plan, and recommendation is grounded in research from reputable scientific journals and public health guidelines. The team integrates nutritional biochemistry, psychology, and behaviour science to craft solutions that truly last.
Clients undergo detailed assessments, including dietary analysis, health history review, and goal setting. This ensures that every nutrition plan is completely individualised, respecting each person’s unique needs, preferences, and lifestyle.
Impact and Recognition
Since its establishment in 2016, the Harley Street wellness consultancy has rapidly grown into one of London’s most respected centres for nutrition and lifestyle guidance. With a small, dedicated team of 2–10 professionals, the clinic has helped transform countless lives. Its influence also extends far beyond clinical practice — through media features, educational talks, and publications, the organisation continues to lead national conversations on responsible, evidence-based nutrition and holistic well-being.
Rhiannon Lambert’s podcast Food For Thought has featured prominent guests from science, sports, and the culinary world, making nutrition education accessible and engaging to a global audience. Her books and public advocacy have further strengthened Rhitrition’s reputation for trust, empathy, and scientific excellence.
Commitment to Holistic Health
Rhitrition operates under a holistic philosophy — that food is more than just fuel. The clinic encourages clients to see eating as a joyful, mindful act that nurtures both body and mind. Whether it’s addressing anxiety around eating, balancing hormones, or enhancing performance, Rhitrition ensures that nutrition is viewed through a compassionate, human lens.
This approach aligns perfectly with the growing movement toward well-being over weight loss, helping clients redefine success as health, balance, and confidence rather than numbers on a scale.
