You cannot measure every morsel that passes your lips, but it is a good idea to measure most foods and beverages until you get a feel for portion sizes.
It is a super sized world out there, and most people are surprised to find that their idea of a single serving is actually two or three.
If you are into bells and whistles, there are food scales that are preprogrammed with nutritional information, as well as scales that will keep a running total of your daily food and nutrient intake for you. The only tools you really need, however, are a simple and inexpensive gram scale, dry and liquid measuring cups, and idea on reading food labels.
