I am 18 days into the program and my first 2 weeks i was happy i lost 5.5 pounds. Now i am almost finished with my third week and have not any more weight loss. I only fluctuate. I am a bit frustrated too but I know I have to hang in there because I will regret it if I don't. Just think, it is better to lose something in (whatever time frame) or stay the same, then to go off and waste all the hard work put in and gain it all back. As long as I am not hungry I can hang in there and that is the beauty of the diet. You can eat until you a full. I have been on calorie diets and the weight comes off at the expense of being hungry all the time! Who can stick to that for months? Not me. Anyway the others are right. Fluctuations on the scale are natural because it is not fat weight but only water. Hang in there. You will not regret it.
