I know the snack was not the primary focus of the article, but it just happened to be what I needed most right now. Cynthia, controlling snack portions and how often we eat snacks is so key to weight loss and maintenance Glad it was helpful!

This is easier to do with cheese, especially appreciate the cheeses made by Cabot, almost all if not all are marked lactose free. Kraft shredded Mozzarella is also lactose free.
