I just want to share with you this diet that I have tried sometime in 2009. I lost roughly around 10 lbs in 1 week. Although this diet is not recommended to last for more than a week, it can help give you a quick start in losing weight. I have really slow metabolism and I gain back weight easily at the moment I go beyond the 1200-1400 cal intake that was suggested to me by my nutritionist. I tried this to see some results and motivate me to my health journey. I am sharing this for reference but please do consult a doctor first before doing this kind of diet. If you have any kidney, heart or liver ailments, then I recommend that you really see a doctor first and ask if this kind of diet will not cause you problems.
