Has SparkPeople's Nutrition Tracker helped you lose weight? If so, how?

How? Omigosh!! Where do I start?

When I began using Sparkpeople in June 2006, I had no idea whatsoever what a "portion" of anything looked like. With the help of Spark, and a really good kitchen scale, I learned that:
-I'd been eating up to three times what I should have been of most of my favourite foods.
-If you balance carbs, proteins and fats that you don't have to eat as much to get full.
-Good food doesn't have to taste like cardboard (thanks to the meal plan).

I lost 30 pounds using my tracker on a regular basis in my first six months on SP.
I still use it regularly for maintenance. Some days I slack, but it's the days following those "some days" that I notice things aren't quite right.
