This is only true for averages. If you do absolutely nothing but lie in bed all day, you don't need 1500 cals. The actual rule is that if your incoming calories are less than the calories you expend, THEN you will lose weight. Then again, Dave has asked for fitness/nutrition help a few times and I've put time into responses and he appears to have ignored them so maybe it's best just not to bother! Shame, because it's pretty much all I think about when I'm not selling stuff. EDIT: and yea, that Paul McKenna thing is great. It's worked for my mum as a really simple way to lose weight and feel good about yourself. It helps if you enjoy good food though!
