Oh my auntie's on that, she's lost 2 stone in seven weeks! I don't know what she looks like as she's in another country but she must look amazing. Personally I couldn't do it if I needed to but she's stuck to it and it's paid off. She says it's really hard though, you've got to drink three shakes during the day and then eat a salad for dinner. They are special shakes you have to buy from this company though.
