I entered my current weight (158.5 -- there, I said it) and my goal weight (I'll let you know that one later, when I get there), and it calculated what my daily caloric intake needs to be. It takes into consideration your height, age, and current activity level. It estimated how many calories I am consuming in order to be the weight I am, and told me how many calories, per day, that I would need to decrease that by. It's do-able. And being aware of what I'm eating will help tremendously.
To that end, I have begun keeping a log of what I eat each day. It will take a few days to remember to enter everything -- and I mean everything -- that I eat, but I will do it. I'm going to carry a small notebook and, if I'm not at home, write down what I eat and enter it into the program later. I want to be aware of what I'm putting into my mouth, because mindless eating will get you in the end (pun intended). Trust me, I know.
There are more features I haven't explored yet, but I will. It even provides an area for journaling, if you are so inclined. There is a section where you can record your daily workouts, but I'm not sure if I'll use that. I've gotten used to using a workout log that I created, recording which exercises I do, and how many sets and reps. But if I decide I like the FitDay method better, well, I have no problem using something that works better for me.
It took me a few days to get in "the zone," but I think I'm there. I'm ready to do this and do it right. I'm tired of making excuses and, little by little, seeing the pounds creep back on. How about you?
