We propose an alternative approach to the 1/D-type expansions for evaluating properties of generalized Gutzwiller wave functions (GWF's) in low dimensions. Our expansion uses the sum rule and symmetries of the trial wave function explicitly. We apply the scheme to an antiferromagnetic generalization of the GWF for the ID Hubbard model. We find good agreement with known results from variational Monte Carlo calculations and a significant improvement over previous approximations.
