While I have not had to do the restart it all yet, based on times that I have plateaued in other programs in past weight loss Journeys, the theory behind it is that you change the amount of calories coming in, you change the amount of food coming in, and what it does is changes how your body responds because when you hit the plateau a lot of times it's because your body is on the edge of a starvation mode and thinks that it's not getting enough so it slows the weight loss down, this is more common in females because we bare children our bodies don't like to let go of storage just in case sadly it does not get any easier when we get older and come out of childbearing age. So the restart is sound Logic and other people that I've seen post about it have seen success with it so there's nothing to lose, except for more weight!
