The point system is not the same for everyone. It all depends on your body structure, how much weight you have to loose, etc. For instance, when I was on WW after the birth of my first child, I was allowed more points than normal because I was nursing. Once I stopped nursing, 8-10 pts/ day were taken away. Additionally if you are working out, depending on the activity level, you are allowed several pts per the day you work out.
Titchou was correct... there are a lot of foods that have zero pts. For instance, most non-starchy veggies. My aunt ate that nasty cabbage soup all day long when she got hungry in between meals and it was only 1 pt per bowl.
The more fiber in the food, the less pts. Fruits are a different story due to natural sugars. Portion sizes are a big factor as well. WW usually suggests 3-4 oz of lean protein which is usually 1-2 pts per ounce.
WW is an easier way to count calories. However, it's also a learning mechinism on what foods you really should be eating and portion sizes. It's an easy, healthy system to follow and I highly recommend it.
