Anecdata: I stuck with CICO + IIFYM and strictly kept track of everything manually using a scale, excel, and nutrition labels. I lost 30 lbs in 3.5 months almost exactly in line with my calculations. A big factor was "standard days/meals" so that I could just measure food & re-use previously entered numbers to save time and hassle. Admittedly, my diet was boring. But I didn't care because my results were so clear. From my interactions with lots of people whom CICO+IIFYM fails, they seem to not be actually tracking their intake precisely and honestly.
