A new class of relativistic stellar structure equations which include the antiscreening effect of the gravitational interaction is presented. Significant modifications in the mass-radius relation for neutron stars can be expected if the running of the Newton coupling due to quantum gravity occurs at low energies. A new Buchdahl limit is derived and its physical implications are discussed. In particular, sub-Planckian self-gravitating objects with arbitrarily small radii are possible.
