Wolf Funfack

Wolf Funfack dedicated his life to the research and treatment of obesity and diet-related diseases. In his practice in southern Germany, he began treating several patients with obesity and prediabetes. At first, he used traditional methods of treatment, but out of necessity, he was compelled to develop his own program. He lived strictly by his own program before treating patients by means of individual nutrition plans. He continued following his own program and successfully treated many until his death.

Silvia Bürkle is a food technologist. During her time in the food industry, she soon understood the relationship between supermarket foods and poor nutrition. Sylvia therefore became the mastermind behind the plan. After painstaking work, she classified foods by their components and allocated nutrients to symptoms of deficiency. With that knowledge, she went on to create the framework for the computer program on which all Metabolic Balance® food plans are based.
