Apathy attacks and Porridge

Sooooo I have had a 3 day apathy attack - mainly induced by getting pissed on Saturday night and having to spend most of Sunday in bed.  This has had two effects - one I haven't done any exercise apart from press-ups and two I have eaten my bodyweight in chocolate and curry - apparently neither of these are conducive to weight loss!
I did however have the time to contemplate how I am going to achieve my goal, and more importantly what my goal is (other than some amorphous ideal of being thinner).  I went to a triathlon workshop organised by the lovely people at Moti http://www.mymoti.com/bristol/ and run by Andy Bullock who is a renowned triathlon coach http://www.escoach.co.uk/index.php. He got us to focus on goal setting and then looking at how we could actually achieve those goals, what things would be likely to scupper our plans and what things we could rely on to keep us going.
As it seems to be accepted that diet plays more of a part in weight loss than exercise I thought I would turn my mind to that subject.  I can't really be doing with crazy fad diets - paleo, Dukan etc but I do think that there is something in the GI diets that aim to keep blood sugar level and therefore insulin in check.  Being a sugar fiend I know that this is my downfall.  I also read recently that the most effective diets are actually the ones that are low in fat.  So low sugar, low fat and low GI carbs is what I should be aiming at (says the woman who had a biriyani with naan bread and a chocolate rabbit to eat yesterday!)
I found a living social offer for Diet Chef http://www.dietchef.co.uk for a week's worth of 3 meals a day plus a snack for £26.  As I spend stupid amounts on food (and my Mother is nagging me to save for a deposit for a house) I thought I would give it a go - in theory I shouldn't be able to kid myself about what I'm eating as I am only supposed to eat what's in the box and additional veggies and NOTHING else (yikes!)
The box turned up yesterday with the meal choices I had made (who plans every meal they are going to eat for a full 7 days ahead??) and I started this morning (hence the curry and chocolate yesterday).  I'm not normally very good with these sorts of things - I tried the weird eat nothing but horrid tasting milkshakes diet by LighterLife and I lasted 15 minutes - so I wasn't holding out much hope.
 The morning porridge - 40g of porridge oats with cocoa nibs with 120ml skimmed milk - was fairly unappetising, but I can get used to it and I found out I can use more milk as I have an allowance for tea and coffee which I don't drink.  Sweet potato and coconut soup was ok, but very salty and I had to have one of my teeny tiny carboard dark chocolate oat biscuits to cheer myself up immediately afterwards (I'm saving the other one for my mid afternoon craving which already makes me sound as if I'm on a desert island hoarding food).  The evening meals are all in microwaveable pouches and look ok - it's just that I'm not a fan of the fake additive aftertaste you get in these things.  However for £26 it's less than I would normally spend on food in a week (I am dreadfully wasteful and also treat myself all the time)so I thought I would see if it was a way of kick starting some weight loss and also weaning myself onto smaller portions without having to think too much about it - we shall see.
 I have to weigh myself and measure some bits of my body to see if the week of abstemiousness (abstemiosity?) makes a difference and if it does I might be encouraged to be stricter in my adherence to porridge, soup and an evening meal with lots of veggies and a small portion of brown rice, wholemeal pasta or sweet potato (and I might be able to save more towards that house my Mum wants me to buy!)
