Simply filling is where u eat the food marked green in ur pocket guide u eat as much as u need to feel satisfied not full if u eat anything not highlighted green u need to point it. U don't point or measure out the green food but u do the other food not highlighted, if u go to the top of the page there is a separate thread that says simply filling in there there is also a food list with all the filling and healthy food and a thread explaining it a little better, let us know if u find it ok
