Abstract: By means of a Kaluza-Klein type argument we show that the Perelman's F-functional is the Einstein-Hilbert action in a space with extra "phantom" dimensions. In this way, we try to interpret some remarks of Perelman in the introduction and at the end of the first section in his famous paper ( Perelman in The entropy formula for the Ricci flow and its geometric applications, 2002). As a consequence the Ricci flow ( modified by a diffeo-morphism and a time-dependent factor) is the evolution of the "real" part of the metric under a constrained gradient flow of the Einstein-Hilbert gravitational action in higher dimension.
