I didn't start out that low with cals, its just what I ended up with at the end of my diet, afaik I think I started cutting at around 3500cals pd. I keep fats low by not adding any to my diet and only having lean protein sources
yes I know its crazy but it didn't hinder my progress so I carried on with it 
 
And far from massive - yes definetly mate once this week is complete I will post my experience and results
