i went on this diet , i was on it for a month , during this month i suffered from imence tiredness and lethargy , i took all the nessassary vitamins and supplements , untill i ended up at the docters extremely unwell and was diagnosed with a kidney infection , when i told the doctor i was on this diet he explained that this may well be the cause of my illness and to stop it emedietly ....i did lose half a stone in this time but it was due to my illness more than the diet ...its extremely bad on your health and i would NOT advise anyone to try it !!!
