Competence Center for Integrative Obesity Medicine

Arrive healthy and happy in your feel-good body

Would you like to see extra weight melt away, while feeling at ease in your new body? BeLight Medical is the first institution in Switzerland based on innovative medicine and technology, combined with Traditional Chinese Medicine and other holistic therapies. Together, we will design an integrative therapy plan based on the BeLight Cycle, with integrative treatments and medical supervision as the foundation.

Continuous care — the BeLight Cycle

We care about your long-term success.  That’s why we work closely with you to design a holistic therapy that is individually tailored to your needs, based on the BeLight Cycle. Our integrative approach provides a positive experience, sustainable results, and a feeling of well-being. In addition to professional support of our doctors, our team members and TCM-experts will discuss nutrition, exercise, relaxation and beauty treatments with you.


Integrative Medicine

We’ve created a medical program based on the latest findings from scientific research, combined with the ancient knowledge of Traditional Chinese medicine. Our innovative therapy is based on Dr. Sonya Hansen’s approach. It has been used successfully in Hawaii for over a decade and does not require amphetamines. In addition, we use Chinese herbs and teas to help support weight loss and improve your well-being. During our weekly medical sessions, we make sure that you are on the right path to your new healthy and slim body.


With a clear understanding of what is good for you, you can allow yourself to enjoy a variety of tasty foods again. During our one to one coaching session, we will create a tailor-made yet simple plan with balanced, wholesome and organic foods that are adapted to each season. We supplement this plan with Chinese herbs and teas. During our weekly progress checks, adjustments can made to help you reach your goal.


Because regular fitness training may stress and strain joints, we offer Aqua Biking, a gentle but effective form of exercise. Up to 600 calories a session can be burned in half-an-hour. The Aqua Biking lessons take place in an individual private booth, in our new practice in Zurich. In addition to the weekly Aqua Biking lessons, we give you fitness tips.


In order for you to feel comfortable in your new slim and healthy body, we offer beauty treatments. Different technologies such as the Verju Laser, Velashape, and Cryosauna, as well as specific massage techniques, are used. Some beauty treatments can increase blood circulation and carrying off waste, while others can reduce cellulite lumps and bumps, creating a smooth slender form.

Verju Laser


  • Reduces body circumference.
  • Stimulation of collagen synthesis and thus reduction of cellulite.
  • The fat content of the fat cells is effectively removed from the body.

The Verju Low-Level-Light-Laser (532nm wavelength) uses photon energy to identify the photoreceptors of the fat cell. This absorbs the energy and creates a pore in the fat cell. The released lipids of the cell escape from the cells and are degraded by the lymphatic system. The fat cell itself collapses and shrinks, which has a direct influence on your body circumference.

The advantage of the Verju laser is that you do not feel any pain or other irritation. You do not need to recover after the treatment.

We recommend that you spend 30 minutes on the Aquabike immediately after the treatment. This accelerates the breakdown of the released fat lipids via the lymphatic system and thus increases the effect of the Verju laser.

The following results have been proven in a clinical study.

Clinical Study: Reduction of Body Circumference 2014

 Waist  4.47 cm
 Upper abdomen   3.3 cm
 Hips  2.92 cm
 Right thigh  2.72 cm
 Left thigh  2.34 cm
 Total  15.78 cm

  • You lose between 300 and 600 calories per 30 minutes.
  • Increases your fat metabolism.
  • Improves the performance of the cardiovascular system.
  • Helps with lipoedema and heavy legs.

On the Aqua Bike, you sit on a bike in the water and pedal against it. The water reaches about up to your hip. Aquabiking is an effective whole body workout that keeps your circulation going. The buoyancy of the water protects your joints and ligaments during movement and reduces the subjective perception of exertion.

Water conducts much better than the air, so the body transfers the heat into the water to balance the body temperature. This in turn requires energy, which increases the body's metabolism and thus promotes weight loss. The next day you will also not have sore muscles, because the muscle tension under water is lower and the muscle relaxes.

Finally, Aquabiking also helps against cellulite: the massaging movement of the water stimulates the blood circulation of the skin and tightens the tissue. It is the most effective method against lipoedema.

Of course the water is changed after each customer.

Chinese Medicine and Weight Loss

How does Traditional Chinese Medicine look at weight loss?

2000 years ago, Huang Di, the father of Traditional Chinese Medicine, known in the West as the Yellow Emperor, had already realized that obesity and overweight is the result of a person's constitution (body predispositions according to Yin Yang and the 5 Elements Cycle), bad diet habits and lifestyle, and is strongly impacted by emotional stress or disorders. Under those circumstances, the body accumulates dampness, phlegm, and water, which we recognize today as additional kilograms.
Unfortunately, gaining weight gets easier with age. TCM therapists have long known that after age 40, yin qi (substance) increases in the body, and over 50 the body naturally starts to accumulate dampness, phlegm and water. The phenomenon ancient doctors had described thousands of years ago is now confirmed by endocrinologists to be hormonal changes during the menopausal period.

What is most important from our perspective?

According to Traditional Chinese Medicine, all humankind is a mixture of five elements: Water, Wood, Fire, Earth, and Metal. Those five elements predestinate our morphology as well as how and where we gain weight. We know, for example, that some of us will have “problematic areas” on the belly and back, while others will have these on the thighs, hips, and bottom. The key to health, longevity, and healthy body weight is a good first diagnosis. This is done by taking into consideration the above-mentioned patient's constitution, diagnosis from the pulse, the tongue, and an interview.

After determining the proper diagnosis, a TCM therapist uses techniques such as acupuncture, herbs, and tui-na (healing massage) to improve the patient’s digestion and metabolism, increase the conversion and discharge of moisture, boost the transformation of food into energy and move the energy in the body. In Western medicine, this would mean to jump-start the metabolism again.

Thanks to this treatment, we can correct stagnation and eliminate water retention. It is the fastest way to a patient's desired weight, and success is maintained in the long term.

Unfortunately, the times we are living in now are much more complicated than they were two thousand years ago, and to fulfill its demands we need to be integrative. That is why the Be Light Medical concept is based on five important pillars in which both Traditional Chinese Medicine and Western medicine play an important role.

How do I get started and how does the program work?

We believe that your long-term success in weight reduction can be ensured through an integrative program with consistent medical support and holistic therapy. Our process consists of:

  1. An initial discussion, with no further obligation, to explain the program and answer any questions you might have.
  2. A detailed preliminary medical consultation with one of our doctors to assess the current state of your health based on your medical history, your physical endurance, and laboratory data.
  3. Creation of an individualized therapy plan for a period of several months up to a year, in addition to a nutrition plan, to help you reach a jointly defined goal.
  4. Weekly evaluation and monitoring of your progress, during which we will renew and adjust your medication, and, if necessary, rework your nutrition plan.
  5. Regular Aqua Bike Sessions.
  6. Innovative measures and new technologies to support and promote your beauty.
  7. Relaxing massages to increase well-being and put you in touch with your body.

Our role doesn’t end when we create your individualized program. We are here to answer your questions, support you emotionally, and discuss your progress. Our doctors are happy to assist you with other medical concerns as well.

What happens afterwards?

  • After several months of therapy, we will reassess your long-term weight goal, as well as other needs. This includes discussing the suitability of continued intensive therapy, as well as considering helpful measures outside of our program.
  • Regular check-ups are scheduled to check on your progress towards your goal and reinforce your new healthy habits.


The total cost of the program is based on your physician appointments and medication, as well as the various holistic therapies you chose during our discussion. After your initial consultation, we recommend you clarify your insurance coverage by speaking directly to your insurer.

How we came to be

I’m Esther Denz, one of the founders of the BeLight Clinic. As an acupuncturist and herbalist, I have been involved with the well-being of women for over twenty years and have accompanied them on their personal journey to find health and balance. Again and again, I find that the challenges women face are in tune with my own life and inspire me to find solutions. I was lucky to find Dr. Sonya Hansen from the Awazul Wellness and Weight Loss Center in Hawaii, who specializes in innovative medical support for weight loss. Through mutual friends I discovered two dedicated and innovative Swiss doctors, who shared my interested in helping women get slim and healthy.

After our team was formed, we contacted Dr. Sonya Hansen and I am pleased that she agreed to serve BeLight Medical as a mentor and coach and to help us develop our concept. She supports our European team every step of the way with her vision and expertise.
