Hey,
even if you drop no weight on the scales on your refeed week, remember you still have lost fat! Your glycogen stores were empty before you began, and now they're full and weigh 3-5lb! Definitely! This wouldn't apply if you were refeeding for more than one week, and you'd probably lose weight if you did it by the book again incl Day 1-3.
WW seems to still have worked for people on here, so it should work for you.
You just need to figure out how many calories you can burn a day, and reduce it by a little to lose weight! Say if you burn 2000 a day, try 1300 to lose weight, and figure out what it is in WW points.
