I understand what you're saying with the calories,but this diet isn't just about calories,its about being in ketosis and using your fat as energy,if you're knocking yourself out of ketosis you won't lose very well, Atkins is a ketogenic diet also and people eat 1500+ calories but still lose a lot of weight because there carb intake is very low,slim and save carb content is higher,but we have lower calories and still use ketosis to lose the weight,if your not in ketosis but eating very little calories your body is going to hang on to anything it can,because essentially you're in starvation mode without ketosis,I understand your disappointment,as I'm feeling it too right now after my slip up,but I've admitted my faults.and accept that if I stick at it next week my loss will be even bigger x
