The low carb program is painfully slow and you are drip fed information as you cannot access more than that week's program - by the time I went back to it and got through to the end I was months into normal readings and had just got a normal Hba1c so I'd not recommend it at all.
I was already aware of what to eat - I'd gone back to low carbing from the moment I was diagnosed, so there wasn't anything I could learn from the program anyway - and it was still free when I enrolled - but the basic rues are so simple - if you need any information perhaps finding a copy of Dr Atkins New Diet Revolution would be cheaper and faster, as there are lists of foods which you can eat freely, ones which you need to calculate, and how to go through the various stages if you want to lower weight, though they are also useful as guides as your metabolism will hopefully get back into balance and enable you to eat a little more carb each day as you shrink down losing fat and resistance to insulin.
