The Six Pillars

I see people holistically and connect the 6 pillars to help my clients. 6 Pillars:

eat – sleep – move – protect – unwind – connect,

Only by combining these pillars will we succeed in transforming your life permanently to a healthier lifestyle.

In my consultations we figure out individually and together, what the right path is for you to lead you to your personal goal. I support you on this path and help you achieve your goal. It involves more than a healthy diet to help you achieve holistic health and happiness in your life.

It is important for me to give each client practical and everyday help that is right for their situation.

Fasting Courses

Fasting gives our body an opportunity for regeneration and renewal. We can assist it on all levels by focusing our attention on the body as well as on our mind and soul during the fasting period. Mindfulness and deceleration are good for our daily lives, and fasting gives us a chance to practice these virtues a little and by doing so being good to ourselves.

  • Fasting weeks after Buchinger / Lützner
  • Alkaline fasting weeks
  • Alkaline reset weekends
  • Intermittent fasting

Contact me for details, group offers or individual support. I am happy to help you.

Self-determined handling of sugar

It is particularly important to me to raise awareness about the influence of sugar on our health and quality of life.

Sugar has the same effects as a drug and its impacts go far beyond our weight, from chronic fatigue and lethargy to cardiovascular disease, diabetes and hormonal imbalances, just to name a few.

I can show you the way to a sugar-free and energized life and accompany you every step of the way. The path is worth it! Overcoming an addiction is never easy, no matter which addiction it is, but especially so when it is socially accepted. Your body will thank you! I use the 3 Ps:

Plan – Prepare – Protect.

If you do not spend some time each day on your health, you will have to sacrifice a lot of time to deal with disease one day. -Sebastian Kneipp

Individual consultations

A strategy session lasts 60 minutes. We record your data as well as your current diet and exercise habits. We talk about your goals and how the 6 pillars can help you reach a life full of energy.

Follow-up consultations usually last 45 minutes. We discuss successes and problems, further steps, help and possibilities on the way to achieving your goal, be it lifestyle changes, nutritional changes or weight loss.

We all have busy schedules in our lives. Do not let that stop you. After the strategy session, consultations can also be carried out via Skype, if required.

What clients say

About the individual nutritional advice consultations

The reason for the three-month nutritional consultations was that I wanted to eat a sugar-free diet due to many health problems and lack of drive due to professional stress and lack of sleep.

My first goal was to eat less sugar / sweets by increasing the amount of vegetables, legumes and fiber. The small-scale goal setting each week helped me a lot.

Thanks to very tasty and simple recipes from Ms. Fliegner, it wasn’t so difficult to try it out. I even enjoyed cooking and became much more open to try new things. (…)

I got to know great alternatives for baking and eating cakes too, but without sugar. (…)

Dear Ms. Fliegner, thank you for your great work (…). Your warm and calm manner, (-), you took me seriously and addressed everything I brought up. (…)

Now it is up to me to continue to put what I have learned into practice! (…)

I can only recommend the course, sugar free can be so easy!
