Yup, I do know!!
That's why I'm lovin' Flexpoints! I agree with you about WW being kind of expensive. But the answers are out there! (Sorry to sound like X Files, xDAS7x!!!)
I don't have an actual URL for this but if you do a search on 3FC for the Laborious Losers thread, which was our thread previous to the End of Daylights Savings Challenge (where I currently hang out) and kind of read through that to near the end, you should find some answers.
The magazine really has a good explanation also. It's basically really simple.
If carbs are a problems for you, there are some poster here having success with the South Beach Diet. Instructions for this are all over the place and there's a book. It looks sort of healthy and it does have a structured plan.
Anyway, good luck ... come see us on our End of Daylight Savings Challenge or any of the supportive threads here if you wanna~!!!
