How long did it take to notice dofference?

as I stated in a previous post I have started drinking heavy cream about 2100cal worth a day how long do you think it will take to notice any difference in body composition or fat gain? I'm going to be doing this for a whole month and I have also quit going to the gym aswell, I previously went for a couple hours every day, in addition to this I might try to shoot for even more heavy cream on weekends to speed up the process even more.
