sounds a bit like the wendy plan but stricter
500 cals doesn't go very far but doable
I should research this. Good Luck 
when I search all I get is Attention Deficit Disorder
and i'm sure its not related to that. 
wonder if you could have a few more cals say 700 and it still work
I know the old w/w wendy plan was very similar but not as strict. Must work because the guinea
lost 3lbs her first week
