I've been doing WS for a month now and my losses haven't been that great compared to others but they are mainly on TS. My shape has totally changed though. I did TS for about 3 weeks i lost about 9lbs then changed to WS and I finally hit the 16lbs mark on Saturday after 4 weeks on WS. I had a meal out on Sunday night and haven't lost anything this week yet but I expected that as it was loaded with carbs, it was a birthday gift from my dad and had been planned.
Look at my losses under here and you can see how it's gone. I have 17lbs to go, I really hope it doesn't take another 8 weeks though. I haven't been doing exercise though due to health reasons but I have been feeling so much fitter an lighter on my feet I expect I can manage some from the weekend and perhaps that will help speed it up.
Everyone is different though, you can always try TS like I did, I love doing it, I would prefer to do it, but it just made me ill, dizziness, heart racing, things going black, but a meal of chicken and veg made all the difference and I feel human again. I am on medication daily though so perhaps that was a factor.
These diets work, you're taking in so few calories that they cant help but work, I think it's just down to your body and how it deals with it, I find it a whole lot easier than weight watchers and the like because you don't get treats, you have to stick to it and I find that I don't crave anything. The nibbles I've had of things I have liked the look of, none of them have tasted as good as I imagined they would.
Sorry I've gone on so long, hope I've helped somewhere on my mutterings
