About The Diennet Institute EU & UK: Unlock Your Body's Potential for Lasting Weight Loss
Since 1975, the Diennet Institute has been the world's leading pioneer in customized, physician-supervised weight loss.

Instead, we craft a unique treatment plan designed exclusively for you, ensuring exceptional and sustainable results.
Your Personalized Path to Optimal Health and Well-being
At Diennet, we understand that true weight loss success and overall vitality stem from peak hormonal balance. That's why we delve deep into your personal medical history, analyze your unique hormonal makeup, and assess your lifestyle habits. This comprehensive approach allows us to formulate a physician-prescribed treatment that is precisely customized for your body. As you progress, we continuously refine your prescription, guaranteeing your treatment remains effective and delivers maximum, lasting results.

The Diennet Treatment: A Fusion of Global Healing Wisdom
The Diennet Treatment is a sophisticated blend of cutting-edge and time-honored healing modalities: pharmotherapy, opotherapy, phytotherapy, and homeopathy.
-
Pharmotherapy, or Conventional Medicine, provides your body with the precise boost it needs, often in subclinical (very small) doses.
-
Homeopathy, as practiced at Diennet, utilizes these sub-clinical doses to achieve maximum results with minimal side effects, ensuring a smooth and effective journey.
-
Opotherapy, rooted in ancient practices, uses extracts from animal glands to address hormonal imbalances, often referred to as similia similibus.
-
Phytotherapy harnesses the potent healing power of plant and herb extracts, a cornerstone of natural wellness.
A Worldwide Quest for Healing: The Genesis of Diennet's Innovation
Dr. Diennet's relentless pursuit of the world's most effective treatment methods has taken him across continents and cultures. He has meticulously cherry-picked the most impactful approaches from diverse traditions, including the profound wisdom of Jesuit Priests, the rich heritage of European Herbalism, and the precision of Germanic Homeopathy. His early studies with the Jesuits of the Black Forest instilled in him a deep appreciation for naturally occurring ingredients, a principle now integrated into The Diennet Treatment.
His humanitarian efforts, treating starvation victims in Africa and providing aid during the Nigerian-Biafran Civil War, led him to discover powerful herbs employed by Tribal Witch Doctors, which he seamlessly incorporated into his methodology.
During his service in the Vietnam War, where he established what is now the largest hospital in the Phu My region for polio victims, Dr. Diennet immersed himself in Chinese methods of treatment and diagnosis, adopting practices like Homeopathy and Osteopathy – emphasizing the intricate relationship between the body's structure and function.
The principles of Opo- and Phytotherapy find their roots in the wisdom of Ancient Mediterranean Doctors and healers, particularly their understanding of the Similia Similibus principle's effectiveness in hormone regulation.
By masterfully integrating these diverse methods and schools of thought, meticulously gathered and studied over his more than four-decade career as a Medical Doctor, Dr. Diennet is uniquely positioned to provide you with the perfectly complex, custom-tailored formula designed precisely for your individual needs and aspirations.
