I haven't been following exactly the PM diet but have been averaging 250g protein, 300-400g carb, and around 150-200g fat. This works out at something like 4000-4500 calories per day. Frankly I find it hard to consistently consume this much in healthy calories, not least because my stomach is just not used to eating so much.
I've combined this with SS lifting and O lifts, with only hockey for metabolic conditioning. My weight shifts up and down but this has translated into around a 7-10lb gain over 2 months which is around 3% of body weight. As soon as I stop eating, though, it seems to start heading south.
