Scientific title
Study objectives	To test the hypothesis that an intense nutritional training program (diet, knowledge about diabetes, physical activities and other lifestyle factors) can lead to reduced costs for medication, compared to the standard treatment for diabetes. Furthermore, the impact of the two therapies on the quality of life and differences in the compliance and satisfaction with the respective therapy will be investigated.
