Anticipating weight loss

OK, so I have used a daily deals site (http://www.groupon.co.uk/) to buy a deal on meal replacement diet site BOOSSH (http://www.boossh.com/). This invloved buying 56 meal replacement packs for the low, low cost of £40 - delivery will tell if it's a massive waste of money on some yukky goo or actually a good idea!
So my plan is, I am going to try Alternate day fasting as detailed in this YouTube video (http://www.youtube.com/watch?v=I9MmjbTwS58), basically eating normally one day and eating 500 calories the next. I thought these BOOSSH meals would make this a whole lot simpler on the 'fast' days as the packets are already calorie counted.
The deal voucher doesn't start until tomorrow night so I cannot order until then, but I have registered with the site and decided what I am going to order:
