OP, seriously though, you are quite slim already - I really don't recommend you losing more weight. If you must, instead, I suggest that you should tone: eat lots of protein and then you'll slowly gain weight
then you can work that weight off. No point in losing more weight by doing exercise and just cutting out certain foods because you'll drop to a weight where it'll make you seriously ill and anorexic looking - please don't do that!
I'm quite thin, but I just literally eat anything and everything. I don't really restrict myself from eating certain foods, but I have high metabolism anyway, so any food I do eat, gives me sufficient amount of energy until I need to eat again. One thing I always make sure to eat is breakfast
