James, I've been doing The Zone for the last 11 weeks and I've lost 21 pounds so far.
(I picked "Other" in the poll because, although I do monitor my carbs, it's not all I watch.)
I've done Weight Watchers twice before successfully (plus a couple times where I started halfheartedly and quit <g>) and each time I kept the weight off until I got pregnant again. Our family is complete now so I'd like to take it off once and for all, but I just didn't have it in me to start WW again this time. So I did some research and talked to a lot of people, and discovered The Zone. I can't even say how much I love it. I can't believe that I'm losing weight so well eating foods that I love so much (red meat, nuts, guacomole, etc.) and have deprived myself of for so long under the assumption that "all fat was bad".
The Zone is a 40-30-30 plan, so it's not considered "low carb" contrary to what most people assume. It's a moderate carb (40% of your calories), moderate protein (30%), moderate fat (30%) diet. (30% calories from fat is still considered "low fat" by the AMA though in our country, people now associate all fat with gaining weight. In fact, it's just the opposite since the obesity rate in the US has sky-rocketed since the introduction of all the "low fat" snacks.)
Basically, in The Zone, you eat plenty of carbs -- you just get the bulk of them from fruits and vegetables, and you limit (not completely exclude like Atkins) less favorable carbs like pasta, rice, breads, etc. Plus you are actually *encouraged* to eat good fats like olive oil, nuts, avacado, etc. Now that's my kind of diet. <g>
