How often do you plan on doing this? If you plan to do it frequently, according to what criteria will you be tracking your progress?
I normally do a 5/19 program where I eat between 3:00 pm and 8:00 pm, breaking the fast with a snack and then having a meal a bit later. I lost 8 pounds the first 7 days, which was totally unexpected, then my weight became stable. Since then I've taken a break from the scale and am going by the mirror and the measuring tape. I am getting visibly leaner and my size is creeping down.
