Am I eating enough nutritionally?

When reading your question I was thinking "this sounds great, nice and healthy...wait a minute...where's dinner???' There's a whole meal missing! I guarantee you are not getting sufficient nutrients or energy with this diet. Continue with this but add in a dinner thats high in protein (beans/pulses/eggs) with a good source of complex carbohydrates (brown rice/wholemeal pasta etc) and you will be ok.
