I have heard of carb cycling but didn't really know what it was, so I googled it and found this very good article, in case there's anyone else out there like me who didn't know what it was.

It sound like it would work, and would be easier to follow than straight low carb because you get to eat carbs a couple times a week rather than giving them up altogether. They explain why it works, and it makes sense that one day of carbs is followed by a no-carb day, so it doesn't have time to really upset your metabolism.
I don't think I could do it because I have diabetes and have to limit carbs every day for blood sugar control, but it sounds like a good plan otherwise.
Good luck to you!
