A body supporting structure for a vehicle body has a passenger-compartment section, a front-structure section and a rear-structure section. In order to form the body supporting structure, at least one supporting-structure body is configured as a three-dimensional flat structure which extends in all vehicle directions (x, y, z direction) and includes flat elements, the flat elements which extend in different vehicle directions (x, y, z direction) are connected with the formation of soft transitions, the flat elements are configured with cross-sectional areas which are structured depending on the applied loads, and flat elements with low applied loads or non-loadbearing regions are configured with apertures.
