I have to agree with Geoffers 95% only because my daughter and granddaughter do live without all dairy and cheese indefinately. It doesn't help to keep either of them healthy though.
My granddaughter is 5'8" and 210 lbs and my daughter is 5'9" and 330 lbs.
Both of these young girls tend to eat too large of portions of the wrong foods, ie, chips, cola, cookies, ect.
I am not sure that it would help my granddaughter, but Fitday would work wonders for my daughter so that she could take a look at the truth of her eating habits.
That is exactly what I did and have lost 15 lbs since Christmas.
