Friends on portion control-based diets like Weight Watchers® tell us that they use their FoodSaver® Vacuum Sealer to keep their diet on track. They measure out portioned meals and seal them individually, then mark with the point value so that they can easily heat up the meal or snack with just the number of points they want to use. It saves time, because they don't have to stop and figure out points every time they want to eat.
