Progress Photos

Progress shots from the mornings of days 1 to 5 of the fast. We kept the tripod in the same place of the room each day and I tried to stand in the same place for the same lighting. However, due to the weather, some of the lighting is different for each photo. The main thing I notice from day 1 to day 5 is the tightening up of the abdominals (less water).
