The Method

The healing “Doc Fleck Method” developed by Dr. Anne Fleck combines diagnostics and therapy from classical and innovative preventive medicine including nutritional, and regulatory medicine as well as effective natural healing methods.

It includes the individual search for the cause – the intensive attention to the patient in a personal exchange with the intention of leading a life in health and vitality. This can be achieved through the perceptive early recognition of changes in the physical and mental balance and the targeted stimulation of the inherent self-healing powers of everyone.

The method focuses on health instead of symptom suppression. The proven strategy leans on interpreting hidden causes with care and cautiously recognizing and treating the person in its entirety, integrating all the potential of modern therapies.

The sophisticated combination of approaches is an optimal and proven strategy to develop the best long-term health potential for individuals and significantly improve quality of life.

Every patient carries her or his own doctor inside. Albert Schweitzer



Every person is unique, is different in their lifestyle, and eats differently. Due to diverse tolerances, preferences, genes and lifestyles, blanket medical suggestions are not effective. Maintaining and promoting the health of the individual, optimally from childhood on, is the highest goal of contemporary medicine. Doc Fleck offers a personalized solution for you.

Effective. Simple. Sustainable.


Modern individualized body-mind preventive
care provides the basis of health

The innovative medical check-up according to the Doc Fleck method has enjoyed an excellent reputation for years and offers a customized concept for individuals and companies, unique in this form. The holistic preventive care according to Doc Fleck stands for careful customized medicine and relies on modern diagnostics and sustainable lifestyle intervention.

A Medical Check-up includes:

  • Detailed medical history
  • Innovative laboratory, urine, and stool analyses
  • Diagnostics of internal organs and cardiovascular system
  • Lifestyle analysis (nutrition, exercise, sleep, work-life balance, stress level)
  • Detailed report of findings with individual recommendations that largely dispense with rigid prohibitions and promote one’s own potential for health (e.g., on nutrition, micronutrient supply, stress reduction, sleep hygiene, etc.).

If necessary, we offer you support through medical tele coaching and help you organize medically beneficial complementary examinations. In doing so, our broad network of other specialties is at your disposal. Prevention and healing require HOLISTIC MEDICINE, we want to serve this declaration in the appreciation of your health.


Being SLIM! is not enough! HEALTH is the goal.

Note: 40% of the externally SLIM are TOFIs, “thin outside fat inside”, i.e., externally “thin heavyweights” with internally inflammatory-altered fat cells and the same risks as the classically overweight for heart attack, stroke, diabetes, dementia, and cancer.

We offer:

  • the longed-for exit from a long-standing, unhealthy dieting career,
  • a successful body makeover with sustainable weight loss,
  • individualized guidance on healthy weight maintenance with natural foods,
  • professional long-term support and behavioral coaching as needed.

Our philosophy: We reject the use of overpriced whey protein shakes containing sweeteners, as these have been proven to damage the healthy, slimming intestinal flora and many people unknowingly have a problem with whey protein, i.e., milk protein.


Finding the root of a symptoms changes everything

You feel the burden of symptoms and a real cause is not yet found? Often symptoms are trivialized as normal stress, and those affected are wrongly labeled as “stressed” or “psycho”. In fact, often an agonizing alarm of unrecognized metabolic disorders, vitamin and mineral deficiencies, chronic inflammation, environmental stress, pathological changes in the oral and intestinal flora, or hidden infections, etc. is the hidden cause of many symptoms.

We offer:

  • attentive listening without prejudice,
  • focused search for rootcauses and
  • customized diagnostics (including laboratory/stool/sleep analysis) as the basis of a customized therapy for a new quality of life.


How healthy and energetic you feel depends on the efficient functioning of all organs and optimal detoxification. The targeted promotion of detoxification is essential for the reparative processes in the body and is successfully used in the prevention and therapy of diseases. Among other things, “autophagy”, i.e., the recycling of cellular debris in the body, is promoted by fasting and innovative nutritional supplements (e.g., spermidine). Detoxing and fasting need a solid pre-diagnosis and adequate attention, they are not recommendable for everyone and require a careful look at the indication. Unfortunately, questionable “Detox Specials”, which can even be harmful, advertise with the term detoxification. There is also a widespread opinion that the body “regulates” detoxification on its own. This view is too short-sighted from the perspective of modern preventive medicine. There needs to be a careful and professional approach that can promote your health potential.

We offer:

  • contemporary therapy according to the latest research,
  • individualized concept,
  • focused 7-to-21-day program including analysis of dietary habits and individual recommendations.

How Patients rate us

I have been doing a medical check-up according to the Doc Fleck method since 2007. I am thrilled by the approachable manner, the competence, and the modern approach. Years before, I had already been to other "check-up" facilities through my employer. I was disappointed by this: every year there was a superficial organ check, the laboratory results always showed normal findings, although I did not feel completely fit at the time. Tests such as stool exams or for sleep quality were not offered at all and the recommendations for lifestyle improvement, if any, were only blanket and no real help to me at the time. Now I'm experiencing what modern medicine can do and I'm happy to have a place to go as a healthy person to stay healthy. The recommendations are easy to implement and have significantly improved my health and that of my family.

Andreas G, 49 Years

For years I tried numerous diets without success. After a cancer diagnosis, I realized I had to change something. I first learned about Dr. Fleck's approach through her book Schlank! (Slim!) and from TV. I had to wait a long time for an appointment, but it was worth it. Dr. Fleck convinced me with her knowledge and compassion and developed a plan that suited me. I learned to take care of myself with simple tips and managed to lose weight sustainably. I feel strong and energetic now and am so grateful that I have finally started to take control of my health.

Antje S, 41 Years

I had to drive almost 700 kilometers for my appointment. But it is the best thing that has happened to me. Dr. Fleck has finally found a cause for the diffuse symptoms I suffered from for years and for which I was labeled "psycho". With just a few appointments and the recommendations, my life became worth living again and I am back to living life to the fullest. My complaints (irritable bowel syndrome, migraine, hair loss, weight problems and joint pain) have gone and my former depressive mood has also passed. I am very grateful to Dr. Fleck and her team. Through them I have found not only health but also strength to redirect my life.

Jasmin G, 35 Years

I have been a patient of Dr. Fleck's since 2009, and I go there for my preventive care. Even then, she gave me the best tips to help me get through my very stressful everyday life. I am healthy and go to the practice to stay healthy. I think this approach by Dr. Fleck should be taught in school. My whole family implements the simple recommendations and we have been in great shape ever since, virtually never sick.

Gregor D, 51 Years

Love the holistic and unique approach of Doc Fleck. A top dress for functional medicine in the middle of Europe. I have a long travel to make, but it was the best thing I could do for my difficult health condition. Now after the new strategy I feel so much energy again. I can highly recommend the Dr. Fleck´s excellent methode. It works!
