The simplicity and easiness of lowest order constrained variational, (LOCV), method among the other many body techniques, persuade us to use this method for studying a well known and relatively cumbersome problem, the compact QED in 2+1 dimensions. Various quantities such as the ground state energy, mean value of plaquette variable and photon mass gap are computed.
Finally a comparative look will be made to our results and those which have been carried out by using other many body theories.
