why not to do this type of
diet for 2 weeks, then let your body to adjust (and perhaps to get used to) your new state, perhaps to gain a bit of water and weight back, and then repeat this operation 4-6-8 times, as needed. My reasoning is that it could be milder on the body, less taxing for the kidneys. Perhaps it would cost more, but right now I am not considering this side of the diet.
