But it's annoying to be so conscious of how you eat all the time. There are gadgets that passively monitor everything that happens when you exercise, but there aren't many that do the same with food. Apps like MyFitnessPal and LoseIt! rule dieting, but tracking everything you eat is just as much a burden as it is a perk. Unlike fitness tracking, which the FitBit Force and other devices do passively, inputting food data isn't mindless enough to be convenient or enjoyable.
