Our Ambassadors

Ewa Meurk

Dedicated Health Engineer and Author of the book "Become your own Health Engineer – tools for metabolic health!".

Ewa Meurk is a Health Engineer. She combines her technical background (Master of Engineering from KTH – Kungliga Tekniska högskolan – Royal Institute of Technology) with a solid education from the fields of Functional Medicine, Nutrition and Sports Nutrition. She is also a certified addiction medicine coach specialising in food and sugar.

For many years, Ewa believed that health was all about eating less and running more. But the only results she saw were a lighter wallet and a heavier body. She only started to see improvement when she changed things around and stopped following well-established but outdated recommendations. When Ewa started following a more ketogenic diet, she found herself more energised, healthier and slimmer.

These surprising results sparked Ewa’s lifelong passion for understanding nutrition and health from an engineer’s perspective. Ewa now dedicates all her spare time (as much as she has given her full-time job as an entrepreneur and IT company CEO!) to understanding the science of metabolic health.

In the past decade our understanding of the metabolism, obesity, high blood sugar, and insulin has progressed by leaps and bounds, and Ewa has been working hard to spread this new knowledge. Ewa helped launch FunMed – Europe’s biggest functional medicine doctors clinic. Ewa also runs Elitista – an educational company where she holds presentations and runs courses for people who want to understand their own health better.

Hanna Gillving

Author of the holistic health bible KETO-licious (The best health- and diet book at the Gourmand Awards, 2019).

Hanna has a background in the Swedish investment business, which she left in 2013 after re-evaluting life and going on a personal health journey. Starting off in the jungles of Thailand, she found her love for nature and the power of the breath, when learning the ancient practices of ashtanga yoga. She then continued her wellness journey exploring Scotland (UK) and joining Scottish military fitness bootcamps, located in nature (according to Hanna, glorious Scotland might just be the best gym in the world), before returning home to Stockholm and diving deep into the wells of evolutionary science.

Hanna is a functional medicine therapist, nutritionist and sports nutrition coach, educated at the Swedish Paleo Institute and Functional Medicine Institute in Stockholm, Sweden. She is also a holistic addiction medicine coach, educated at the school of the Swedish expert Bitten Jonsson.

Having healed herself from hypothyroidism, burnout and depression, she wrote the book KETO-licious in which she guides, inspires and share her favourite keys to wellness, better health and 'life in technicolor'.

With a holistic approach to wellness informed by evolutionary science, her mission is to raise the awareness of approved natural methods for finding harmony in life, both through writing and teaching. She is currently working on her next book, and helping people re-learn how to breathe. She is a breath guide and dedicated member of the Stockholm-based community and health center Hale – a place to breathe, connect and grow.

Ida Johnsson

Ida Johnsson – a cancer thriver and green voice in the keto community.

In spring 2019, Ida was diagnosed with stage VI ovarian cancer and, like many cancer patients, she asked her oncologist what she could do to aid recovery and prevent relapses. The reply was "Not too much, go ahead and live your life the way you did before the diagnosis".

With two small kids and a fairly poor prognosis, that was not an option as she believed that keeping the habits that got her sick in the first place probably would be a perfect environment for the cancer to continue to grow and spread. Hence, with her background within biomedical science she was determined to review the evidence base, follow the footsteps of other long-term survivors, and do everything in her control to better the odds.

As a believer in both the metabolic approach to cancer and whole foods plant-based anticancer nutrition, she tried to combine the best of two worlds and started to follow what she refers to as a plant centric ketogenic diet.

To hold herself accountable and inspire others to pursue health promoting habits, she started to share her healing journey and cancer-fighting recipes on Instagram.

If you don’t find Ida in the kitchen, cooking nourishing food, you may find her taking a power walk in the forest, lifting weights, relaxing in the sauna, or spending precious time with family and friends.
