Matter of opinion then , due to lack of minerals the body doesnt hydrate as well and passes better , thus creating the fluid flow needed to start the dehydration process , it is this ongoing flow that is needed to get a good dehydrated effect, it tricks the body into ongoing passing which in turn flows on through out thee dyhydrating period ---- that has been my experiance with over 200 champions I have worked with over the years , but in saying that every individual has different needs and so it needs to be trailed prior to the show rather than just before the show !!! some clients shouldnt even dyhydrate at all !! most compettitiors start the dehydration phase already in a dehydrated state , thus all they acheive is pulling fluid out of the muscle cell thus greating a soft drawn look and not a dry crisp full look !!
