Following his dissertation on the subject of “Obesity in infants and young children,” Dr. Funfack was engaged in the practice of internal medicine and nutritional medicine for 25 years. His many years of experience with different dietary programmes prompted him to search for an effective and lasting method that would restore a properly balanced metabolism and to successfully make long-term weight management a reality. After intensive research he developed the metabolic balance® nutritional programme in collaboration with the food technology engineer, Silvia Bürkle.
