I never used to eat breakfast either, but a spoon and a half oatbran mixed in with vanilla muller light is so quick! and it fills me up for ages too!
I'm currently abroad and muller lights are not available but I mixed 1 0% fat free yoghurt, 2 drops of vanilla essence, a spoon of stevia and the oatbran in a bowl at night, I just take it out of the fridge in the morning and it takes about 30 seconds to eat!
I'd also say you need a bit more protein. scientifically, you need approx 1g of protein per lb of bodyweight in order to retain muscle tissue. (I just looked at your stats - we're almost the same!) How about some skinless chicken drumsticks at lunch? I'm now carrying a tin of tuna in brine for emergencies! I had a lecture yesterday (YES ON SATURDAY!) was supposed to finish at 1pm, he went on until 4pm! my tin of tuna was a lifesaver!
