I have done WeightWatchers in the past and one of the key points that has stuck with me is the importance of "filling foods"
What is a filling food you might ask? Instead of grabbing a handful of raisins a handful of grapes. If you are feeling hunger pangs go for something that will fill you and satisfy you.
For instance a banana over a few m&ms.
I learned that lesson....again just the other day. I noticed that I had eaten my fill of "points" for the day but I was starving. I thought about the things that I had eaten during the day and none of them were filler foods. If I had stuck to the "filler foods" plan I wouldn't have been so hungry, and I wouldn't risk putting more food into my mouth.
