I've recently run across this site:
It's a site devoted to becoming a healthier person - with your diet, exercise, etc.
It's a place where I can enter in all the foods that I eat each day, and SparkPeople adds up all your calories for you. It also keeps track of your whole week of calories, carbs, fat, protein, etc. They give you daily meal plans, if you want to use that feature.
But that is just the start! There are so many SparkPeople support groups! From a group that says how much you want to lose, to many other hobby groups that you can join, if you like! Some groups have challenges to sign up for.
For those of you who want to lose a few pounds, I recommend this site!
