Find the root cause.
Restore optimal health.

Tired of being told your results are “normal” when you don't feel it?
I use in-depth blood, hormone, gut and DNA testing to find what's really driving your symptoms, then build a precise plan to address it.

I'm Mimi Walter, founder of Sundara.

I'm a registered clinical nutritionist, with a key focus on metabolic health, hormones and gut health. Many of my clients come to me after years of being told their results are "normal" while they still feel far from well.

My approach combines clinical rigour with genuine care: I listen closely, test where it matters, and translate complex results into a plan that fits your life.

Real results

Before & after.

Result, clearer skin
‍Hormone & Gut Programme · 6 month
‍From hormonal acne to clearer skinAfter struggling with persistent hormonal acne, we looked beyond the skin to understand the underlying factors contributing to her breakouts.
‍The approach:Gut support: supporting a healthy gut environment and regular elimination to help with hormone clearance.
‍Liver & oestrogen support: targeted nutrition to support the body’s natural oestrogen metabolism and detoxification pathways.
‍Blood sugar balance: stabilising meals and nutrition to support insulin regulation and reduce hormonal fluctuations.
‍Targeted nutrition & supplementation: personalised to her individual needs.
By supporting the gut–liver–hormone connection, rather than simply treating the skin, her hormonal acne significantly improved and her skin became clearer, calmer and more balanced.
Beyond weight loss: building metabolic healthMetabolic Health Programme · 12 month
After struggling with weight and energy, we took a metabolic health approach: looking beyond calories alone to understand the factors influencing her ability to lose and maintain weight.
‍The approach:Blood sugar balance: supporting stable glucose and insulin levels through personalised nutrition.
‍Protein & muscle preservation: prioritising protein and resistance training to support lean muscle while reducing fat mass.
‍Metabolic nutrition: creating sustainable meals and habits tailored to her body, lifestyle and goals.
‍Hormonal & lifestyle support:  addressing sleep, stress, movement and other factors that can influence metabolic health.
The result? 3 stone of fat mass lost, alongside a stronger understanding of how to support her metabolic health long-term.
