Weight / Fat loss

Right, I'm a big fan of this sharing thing so:
What I shove in my face each day:
Porridge/ Protein shake
2 x fruit.
Bowl of yoghurt (Rhubarb and Vanilla Asda Fat Free is winning)
Big Ass salad- which is massive and includes tuna and bulgur and a variety of other stuff
'Nother protein Shake.
Random dinner as cooked by housemates/ me (last night I cooked aubergine chickpea coconut curry with jeweled rice).
I've engineered it to be somewhere under 2000 calories a day, give or take.
No alcohol till exams- so that's easy.

What I do to my Body each week- sort of nicked from Hal Higdon/ Men's Running/ other places I forget:
Monday: 10k running @ pace AM, Circuit session PM
Tuesday: HoP cycling AM.
Wednesday: 10k intervals AM (1 fast 1 chilled), Circuit Session PM
Thursday: HoP cycling AM, Special Circuit PM (skipping, sprints and leg strengthening for running)
Friday: Rest Day
Weekend: 2 of Cardio from: Long run, Long ride, Swim. 1 Circuit session.

Henry, I'd be worried about low level calories you are taking in for the level of activity you are doing. You may be unwittingly hammering your adrenals.
