I read about it in Woman's World, and it looked interesting to me. I think at this stage in my journey, I'm wanting to mix things up a little bit, and this seemed appealing to me, though I've never been tempted by Atkins (though it seems to be working well for you, Shellie!).
The way it's described in WW, you eat very typical food pyramid type foods for five days a week. Lots of whole grains, fruits, veggies, lean protein, etc. That's what I've pretty much been doing seven days a week anyway. But on two consecutive days, you switch to a specified low-carb diet consisting of high-protein, relatively low-cal nutrition bars (2 per day), unlimited veggies, six ounces of lean protein per day, a whole cantaloupe per day, unlimited no-cal spices, and unlimited no-cal beverages.
I'm on Day 1. I'll do it tomorrow as well, and if it works, maybe do it next week too. I'm interested in knowing if anyone else has tried anything similar and what their experiences have been. Apparently, it's something that WW adapted from LA Weight Loss Centers, and if the stats are to be believed, it gets good results.
