I am doing exactly this, except I'm doing slow carb instead of no carbs. I'll tell you my plan then you can decide if you want to try it.
I also have been doing weight watchers. I'm down almost 40 lbs. but hit a plateau in my mind lol! I just started cheating and not tracking and you know the rest. So I got this book called the 4 Hour Body. In it he talks about slow carb eating. I cut out all white carbs, or anything that can be white. So you don't eat brown rice or wheat pasta because it can be white. Anyway, I eat 4 times a day. You eat a lot of protein and eat a bean and a veggie with every meal. I'll give you a typical day...
Breakfast: 2 whole eggs, lentils, broccoli, tbsp of Almond Butter
Lunch: Chicken breast, asparagus, Ranch Style Beans
2nd smaller lunch: Spinach leaf salad with grilled chicken breast and dressing
Dinner: boiled shrimp, Ranch Style beans, grilled zucchini
Ok so you stick with these same types of meals 6 days a week and then on the 7th day you eat whatever you want! It's called a dieters gone wild day lol. Mine was yesterday and I had mexican food, alcoholic beverages, pizza, donuts, etc. Anyway, you do this binge day to spike your metabolism and so your body doesn't get used to the reduced caloric intake the other 6 days. Last week I lost 3 lbs. I haven't done that since I started at weight watchers!!
The way I incorporate this with WW is that during the week on my 6 slow carb days I make sure I don't go over my 29 WW points and on my binge day I don't go over the 29 I would get for that day plus the 49 I would get for the week. It's seeming to work for me so far. You can look up more about the 4 Hour Body online. It was on Dr. Oz so it's all over the place lol. It's been a little hard, but I'm consuming WAY more veggies and am eating no processed foods....except of course on that bad day. I think it's good to have that day to freak out so you don't feel so deprived, plus it's something to look forward to! Every time I craved something during the week I wrote it down so I could have it on my binge day. Turned out I couldn't eat most of the stuff I wrote down because I was so full after my first meal of Mexican food I couldn't eat again for hours!! Anyway, good luck!!
