I actually think you are over-doing it, and that is why you cannot shift those last few kg's. I think you have gotten your body into 'famine' mode. You are exercising heaps, eating none to little protein and your body is thinking 'holy crap! she is starving me so I'm gonna hang onto the last bit of fat I have" As crazy as that sounds it does happen. Your body needs a certain percentage of fat on it to be able to function and when your body senses that you are cutting out too much protein and doing far too much exercise, it goes into a self preservation mode.

Despite what you think, what your 'diet' consists of isn't really that great at all. I would have a bit of a google and see what the max amount of calories are that you need, buy yourself a calorie counter and go from there. Cut back a bit on the exercise for a week, get a handle on the food you are eating and start exercising again. Also how much water do you drink? You will have to make sure that you are keeping up the liquids to combat what you would be sweating out and possibly use an electrolyte drink during exercise to replace lost minerals as your diet doesn't really contain a lot.
