Because I do actually read labels and look at portions...
but a visual is much easier for me to use as a tool when keeping healthy portion sizes in mind.
This infographic from Skinny Mom is a great meal planning aid to keep me on track. I'm often surprised at the way products are packaged and how the portions actually break down - did you know that a package of PopTarts is 2 servings? Or that most "single-size" bags of chips are actually more than one serving? It can be eye opening to look at labels.
Are any of these portion sizes a surprise to you?
