Weight Watchers 7 day diet??

I keep hearing about a weight watchers 7 day diet where you can lose 12-17 pounds in the first week. Has anyone else heard of it know what the diet entails??

TIA!

well i didnt know it was an actual diet but last week, i ate only Smart Ones frozen meals for lunch and without working out (my schedule is nuts!) I lost 5 more pounds

I had been stuck at 165 for months and now its boosted me up again.
Plus, after all that, Im finally down to a size 10 again.

So im guessing that the 7 day plan would really work too!
