Its possible you have lost fat but due to your diet may be a little "flat" due to the lack of carbs in your diet. I think 1 day a week you need to "eat up", that is have a non diet hour at around 3 or 5.30 where you eat anything. Have a chinese, some ice cream or anything you fancy bcos if its done within the hour your body wont be able to digest it all and all that will happen is your metabolism will get a boost and you'll end up going for a good dump which removes toxins from your system.

If you pig out for an hour the insulin release which normally leads to fat storage wont be able to store everything as fat but you will get the mental and physiological boost from the extra calories, the additional carbs will be sucked into your muscles and make them look fuller for the next day or two and your metabolism will be boosted and your fat burning ability will be enhanced because if you are eating this diet daily your metabolism WILL slow down.

You should also be incorporating EFA's into your diet too, they will help prevent your metabolism slowing down.
