One high carb day twice weekly, such as...
Two low carb (Mon/Tues), one high carb (Wed), two low carb (Thurs/Fri) , one high carb (Sat), three low carb, etc...which means you can have a high carb on the weekend probably when you really want it and a break in the middle of the week.

I am just starting out but have done a good amount of research on the internet about this and giving it a go, just starting today. Will try to post pix and progress and ideas as I am successful. And no we do not have to be weight lifters to do carb cycling! There was an interesting article in First magazine about carb cycling 10/26/09. There are some books out there as well, but I am too cheap to buy them when there is so much free information on the internet. I research and take the most common suggestions and have designed a plan from there. I will see how it turns out.
