It's great that you're asking for help! We can encourage each other through this!
I enter my food once or twice a day when I am sitting in front of the TV, usually in the evening. I like to rack up the points, so that encourages me. I also like to run the nutrition report; it encourages me to eat more calcium, or fewer calories, etc. It's a good barometer for how well you're eating, what you need to eat more or less of, etc.
I think it's one of the greatest tools sparkpeople offers because it does all the calculations for you, letting you know where you are for the day.
Keep up the good work. Don't get discouraged; and think of this for life!!
