I asked my CDC to send the following question to Cambridge on my behalf. Underneath is their reply.
Question:- "I am aware CD recommend a minimum of 4 pints of water per day. I see on various forums many CDCs advocating 4 - 6 litres or more per day. Do Cambridge endorse this? As CDCs are actively suggesting this quantity, saying "The more you drink the more you shrink" is there any scientific proof that this is beneficial?"
Reply:-
"As far as the water is concerned, we have no connection with that
phrase, as I am sure you are aware, the forum chat is not endorsed by
the company.
We recommend a minimum of two and a half litres daily, when using any
programme, particularly sole source.
However, once established on the diet, it is perfectly acceptable to
consume three to four litres daily.
Some people, particularly those who were drinking large amounts before
dieting, can drink more than that without any problems.
Everyone's requirement is different.
The thing to remember is to drink the water regularly throughout the
day.
It is not a good idea to go for long periods of the day without
drinking, and then consume large amounts"
