A few things can impact this.  As mentioned above a snapshot will grow in size over time and will make the provisioned storage grow higher than what is seen within the guest os.  In addition the provisioned storage of a powered on VM will also add in the memory swap file of the VM.  Other things can reduce this number as well though, such as thin provisioning the vmdk files.

I now notice a slight increase in the provisioning and I believe that is my swap files.
