About Balanced Nutribook
We believe that understanding your body's unique nutritional needs is the foundation of sustainable wellness. Since our inception, we have dedicated ourselves to providing personalized, science-informed guidance that empowers individuals to make confident dietary choices for their long-term health.
Our mission is to demystify nutrition science and deliver accessible, evidence-based information through one-on-one online consultations. We work with people across France and beyond, helping them navigate dietary decisions with clarity and evidence-based insights.
Our Story
Balanced Nutribook began with a simple observation: many people struggle to find personalized, trustworthy guidance about their dietary choices. Online information is fragmented, often contradictory, and rarely accounts for individual circumstances. We recognized a need for accessible consultations that combine scientific rigor with personal understanding.
Our founder, Marie-Claire Rousseau, spent years working in community health education across France. She witnessed firsthand how individuals felt overwhelmed by nutrition myths, marketing claims, and one-size-fits-all dietary prescriptions. This experience sparked the vision for a platform where educated professionals could deliver thoughtful, individualized guidance through online consultations.
Today, Balanced Nutribook serves as a resource for people seeking clarity on their dietary practices. Our consultants bring diverse expertise in nutritional sciences, food psychology, and practical lifestyle integration. We approach each consultation as a collaborative conversation, helping clients understand their unique nutritional landscape and develop sustainable eating patterns aligned with their values and circumstances.
Every interaction reflects our commitment to evidence-informed practice, client empowerment, and respect for the complexity of individual dietary needs. We continue to grow as a team of professionals dedicated to elevating public understanding of nutrition science across France and beyond.

What Our Clients Say
"
I came to Marie-Claire feeling completely overwhelmed by conflicting nutrition advice online. She took time to understand my actual lifestyle and helped me sort through the noise. For the first time, I feel genuinely confident in my dietary choices instead of anxious. The whole experience was collaborative and evidence-based without being preachy. I recommend Balanced Nutribook to anyone ready to understand their own nutrition.
Claire Montagne
Marketing Director, Lyon
"
Working with Julien completely changed how I think about eating. I spent years treating food as either "good" or "bad," and I didn't even realize how much anxiety that created. He helped me understand the psychology behind my eating patterns and gave me practical tools to develop a healthier relationship with food. His approach is so respectful and non-judgmental. I actually look forward to mealtimes now instead of overthinking every choice.

Software Engineer, Paris
"
As someone following a plant-based diet, I worried that nutrition professionals wouldn't support my values. Sophie was the opposite—she respected my choices while helping me understand exactly how to approach my nutrition to feel my best. She made everything practical and accessible, and she's clearly current with the research. The online consultation format worked perfectly for my schedule, and the follow-up resources were invaluable.
