This may be unimportant to you, but... safety first!
I have Crohn's disease, so am not always able to stomach a healthy calorie count (don't misunderstand, I can pound an entire large pizza after a good bike ride, but on those sick days..). An awesome feature that mfp has is the "If every day were like today... you'd weigh xxx in 5 weeks." I totally dig it, as a psychology…
