Achim Peters

Achim Peters, Prof. Dr. (born 1957 in Dortmund) is a German obesity specialist who lives and works in Lübeck. He developed the "Selfish Brain" theory and since 2004 has been leading the clinical research group supported by the German Research Foundation (DFG) “Selfish Brain: Brain glucose and Metabolic syndrome".

Life

Prof. Dr. Achim Peters

Up until his school-leaving examinations in 1976 Peters attended the Humboldt Grammar School in Dortmund. In the same year he embarked upon his medical studies at the University of Bochum; later he moved to the Medical University of Luebeck. In 1977 he won the nationwide mathematics competition organized by the STIFTERVERBANDES FÜR DIE DEUTSCHE WISSENSCHAFT (FOUNDATION FOR GERMAN SCIENCE). With this success he received a scholarship from STUDIENSTIFTUNG DES DEUTSCHEN VOLKES (SPONSORSHIP FROM THE GERMAN PEOPLE). In 1983 Peters received both his medical license and his research doctorate (at the Institute for Anatomy in Bochum).

In 1984 Dr. Peters started working at the Clinic for Internal Medicine at the University of Luebeck. Between 1986 and 1989 he was funded by a postdoctoral grant from the DFG at the Hospital for Sick Children in Toronto, Canada, where he researched on "The Control Theory with Diabetes Mellitus". In the following years Dr. Peters specialized within Internal Medicine in the fields of Endocrinology and Diabetology. In 1993 he became assistant medical director at the Clinic for Interior Medicine at the University of Luebeck.

In 1996 he received his habilitation on the Control Theory of Diabetes Mellitus, and his authorization to teach Internal Medicine. For this work he received the Silvia King Award from the German Diabetes Association. In 2000 he became a specially appointed professor at the University of Luebeck. In 2002 he was promoted to assistant medical director in the field of Endocrinology and Diabetology. In 2004 Peters was appointed head of the DFG Clinical Research Group "Selfish Brain: Brain glucose and Metabolic Syndrome". In the following year he became a faculty member of the “Faculty of 1000 Biology ". In 2006 he was appointed as University Professor of medicine/endocrinology and diabetology.

Prof. Dr. Achim Peters is married, has two children and lives on a farm near Luebeck.

Research strongpoint: "Selfish Brain" theory and obesity

In 1998 Achim Peters formulated the basic model of the “Selfish Brain" Theory as well as its axioms. His explanation of the Selfish Brain" theory (2004) was based on approx. 5000 published data records from classical endocrinology-diabetology and the modern neurosciences, but argued from both a mathematical standpoint using differential equations, and from a system theoretical standpoint. This represented a completely new methodological approach, even a paradigm shift for obesity research and diabetology.

The "Selfish Brain" theory states that the human brain during allocation of the organism’s energy supply covers its own comparably high needs with the highest priority. The brain behaves selfishly in this respect. In the cerebral hemispheres, the integrating organ of the entire central nervous system, the theory introduces a feedback loop of an “Energy on Demand" system that keeps the ATP concentration in the nerve cells of the brain at an appropriate level. This goal is achieved in healthy individuals by allocating (diverting) energy from the body.

The "Selfish Brain" theory represents a further development of already existing theories on the organization of the energy supply within the human organism. Blood sugar and fat deposition feedback systems constitute a complex system for regulating the intake of nutrients which is controlled by a hypothalamic center. The "Energy on demand” system for energy supply to the brain is seen as a supraordinate instance of this setup, which exerts control over the organs that regulate the blood sugar and fat feedback loops.

The origin of obesity (severe and diseased form of overweight) is explained by the "Selfish Brain” theory as an allocation defect. Instead of requesting energy from the body, energy is added by consuming foodstuffs. This results in an energy accumulation in the supply chain, a chain that leads from the environment through the body up to the brain as the end consumer. The possible causes underlying this are localized in impairments of the amygdala, the hippocampus or the hypothalamus. i.e. brain areas that control blood glucose and fat feedback loops and which for various reasons can not correctly process the signals from the cerebral hemispheres for controlling the energy supply of the brain.

The "Selfish Brain" theory has been reinforced in central aspects by the DFG supported Clinical Research Group "Selfish Brain: brain glucose and metabolic syndrome" using experiments carried out on both healthy and diseased test subjects.

Quotes

"Efforts to treat and prevent these public health disorders can only be successful if the overriding importance of the brain is considered in the future." (Overweight, diabetes and lipid metabolism disorders in "Welt am Sonntag", No. 10, 5 March 2006, pp 77)

"The copious amounts of advertising that we are exposed to can already result in the brain forgetting how it should request energy. We can assume that there are dozens of ways that obesity can arise via this route." (The Causes of Overweight in "Neue Züricher Zeitung am Sonntag", Nr. 11, 12 March 2006, pp. 69.)
