As an engineer by training, I find quantitative analysis -- numbers -- an expression of control. Self control, exercise, body function, health and illness... So while I'm fortunate enough not to have to be "Bionic Betty" with a peripheral pancreas, I still refer regularly to six separate instruments, plus additional Web-based resources, to manage my food intake, exercise output, and biometric information.
Weight. Some folk say weighing once a week is enough, but I find that if I don't weigh in every morning, my weight can go off on very health-unfriendly curves. I log my weight both in The Daily Plate and in my personal Excel workbook.
