What on earth was it trying to prove? The bloody Cambridge diet came up as number one, even though they kept saying things like 'it's not recommended as a healthy diet' and 'you shouldn't just go for quick-fix rememdies', then they ranked them on just that!
Also, I missed the first 5 mins but am not aware of them saying at any other time how long the women were on each diet for - 2 weeks? 3 weeks? anyone know?
