I use a program called BalanceLog. I like it because I can use it either on my PC or on my PalmPilot. You set up a profile and answer questions and it will give you what calorie level you should be at to lose whatever many pounds by the goal date. I put in a pound a week. Then you can put your weight in and it will graph it for you. It has a line for what your progress should be. So if my weight is at or below that line I know I am on target.
You can pick what diet you want - most of them are the ADA guidelines .. their low carb option is really not all that low carb. But you can also customize, by percentage, fats, carbs, protien. Then it will track how you are doing with those too
I personally think they are a little stingy with the calories, but if you do a food log it sure is nice to just be able to carry that PDA around and enter food pretty much as you eat it.
