I know this is going to sound silly to some, but for me the first step and actually starting to monitor my food is a success to be celebrated -- I tend to be a habitual snacker, so being able to *not* shrug off my desire to lose weight and say, "Oh, I'll start this tomorrow." is a big step for me. I've been starting tomorrow for years now.
Anyway, I signed up for an account at fitday.com and tracked everything I had today. I set a calorie goal of 1300-1600 for the day, and ended the day at...1598. I tracked my food yesterday at the end of the day without trying to change any habits (i.e. munching and grazing my way through the day like I normally do) and I was at around 2500 -- oddly enough, I was maintaining my weight at that amount, haven't gained anything in about a year (well, except for the mystery pound or two that show up and go away every few weeks or so...).
I didn't do any extra exercise, but I figure at least I did *something*.


) to fill out! I started out by writing 1 Coke instead of 2 (for lunch, "snack," and dinner) because I was mortified to have her see that I was drinking a six-pack a day! She never caught on to me (I don't think), but the day I walked into the gym and handed her an honest food log was the day I TRULY started the journey. It is a HUGE step to be honest with yourself...I think it's half the battle to admit where you're "weaknesses" are and to face them head on. Coke was my weakness, and it wasn't until I truly faced the fact that I was drinking 5 - 6 cans a day, that I realized how poorly I was treating myself. 
Fitday is a godsend! (As long as you're honest with it!)
