p90x

 Hello everyone!, I recently started p90x. i love the work outs but the diet is killin me! I am 9months post op with a realize band. i usually stick to around 900-1000 cal a day.  does anyone else do this diet or just modify their post op diet? 

any tips would be great! 

 I was thinking of ordering it.  What diet does it say to follow?  That doesn't sound like a lot of calories for as hard as you are working out!
