To combat this global health crisis, effective medicines are essential. Prof. Matthias Tschöp from Helmholtz Munich and the Technical University of Munich (TUM), a pioneer in this field, has deciphered the central mechanisms of weight regulation and developed medicines that treat or prevent obesity and its consequences more effectively than ever before.
