CWP's official line is something like '2.25litres minimum, don't drink more than twice as much as that, unless you have bars and tetras in which case you need a bit more water to compensate'. If it was true that 'the more you drink, the more you shrink', CD would be promoting it, as would all the other VLCD companies, as official advice. And so would evian and volvic!
