Sushi fasting at marienkron

Experts at marienkron on the creation and effectiveness of the concept

Dr. Ulrike Göschl – medical director of marienkron, therapeutic fasting

Dr. Ulrike Göschl, medical director at Marienkron, fasting and Kneipp physician, general practitioner and specialist in physical medicine, explains: 
“Fasting is not a diet, but an exceptional state. During the strong reduction of calories, the body shifts from sugar metabolism to fat metabolism. In this process, unnecessary or damaged cell components are broken down and recycled – a mechanism called autophagy. This self-cleansing process is the key to the success of fasting.”

She continues: “The special advantage of sushi fasting is that guests still experience the feeling of a ‘real’ meal. This makes the fasting period easier and helps reintegration into everyday life after the retreat.” Fasting, she emphasizes, is possible all year round, not just in the traditional fasting season. But while many find the thought of hot soups in summer discouraging, Marienkron now offers a refreshing alternative with sushi fasting.

“From decades of experience and scientific studies we know that fasting positively influences early metabolic disorders, joint problems and stress symptoms. The effect lasts for months beyond the fasting retreat.” With the innovation of sushi fasting, this benefit becomes part of a modern lifestyle concept that ensures lasting wellbeing.

“We are breaking with the dogmas of fasting and want to make retreats attractive for younger people as well. Fasting does not always have to mean strict endurance or absolute abstinence. That’s why we developed a concept that offers full flavor even during fasting – and a great alternative in the warm summer months. Thanks to the creativity of our kitchen team, the healthy components of sushi are highlighted so that our fasting guests can enjoy without compromising their results.”

Sushi fasting is similar in structure and calorie intake to Marienkron’s vegetable fasting, with 600–650 calories daily, enough to trigger autophagy, the body’s regenerative process. Herbal cocktails, green tea, ginger water or simply clear water support detoxification. As the program avoids animal protein, sushi fasting also provides anti-inflammatory effects – especially helpful for rheumatism patients. “Because the meals are reduced yet balanced, fasting becomes easier, and guests can also avoid the dreaded yo-yo effect afterwards. I am convinced this new approach will be highly successful,” Karner adds.

Head chef patrick posch on developing sushi fasting

“Traditionally, sushi relies heavily on salt, sugar and alcohol for flavor. Since these are avoided during fasting, I initially doubted whether it could be both fasting-appropriate and tasty. But our kitchen team embraced the challenge and created sushi that is light, balanced and full of flavor. We reduced everything – but without compromising enjoyment.”

At Marienkron, instead of salty soy sauce, a rich reduced fasting broth is served. Homemade fermented vegetable dips add complexity, while maki fillings feature lightly poached regional vegetables to preserve nutrients and improve digestibility. “To stay true to the alkaline fasting principle while keeping the authentic sushi experience, we use beets and carrots marinated or smoked in place of fish. Whenever possible, we rely on local produce from the Seewinkel region – even organic Seewinkel rice. I am delighted with this innovative creation and eager for our guests’ feedback,” says chef Patrick Posch.

With this reinterpreted fasting concept, Marienkron aims to inspire and make the path to health-enhancing fasting both accessible and enjoyable. For a complete experience, sushi fasting can also be combined with one of our yoga retreats – offering new strength for body and mind.
