A new beginning

A retreat that stays with you

Fasting is a wonderful way to cleanse body, mind and soul. It has a lasting, positive effect on your health and is known to be both regenerating and rejuvenating.

When you decide to embark on a fasting cure and fully give yourself over to the experience, it feels like a fresh start. A fasting week is a chance for some personal time out, to turn your attention to what truly matters — it leads to greater vitality and a deeper appreciation of life's pleasures.

Therapeutic fasting

With therapeutic fasting you consciously go without solid food for a set period and nourish yourself with liquids alone. Beyond detoxification and regeneration, a noticeable inner clarity often emerges — a small, holistic transformation.

  • A purely liquid diet
  • Detoxification & regeneration
  • Medically supervised

Alkaline fasting

With alkaline fasting you eat only alkaline dishes in small quantities — a gentle method, close to everyday life and ideal for getting started. The low-acid diet eases the strain on your body and gets your metabolism going.

  • Light, alkaline dishes
  • Gentle & true to everyday life
  • Ideal for getting started

Fasting together

It's easier together

Fasting in a group often comes more easily: you share the experience, encourage one another and live the week more intensely. On the demanding days especially, the shared exchange carries you through.

Guided by fasting leader Barbara Walter, the week becomes a mindful retreat — for new energy, clarity and a fresh start that stays with you.
