I believe Rosedale has it right.  While what follows is a summary what
he recommends, you really need to get his book (*The Rosedale Diet*):

Very low to zero non-fiber carbs.

Three to four pack-of-cards-sized portions of lean protein a day. 
[Check out pages 207-210 of Rosedale's book for your exact
recommendations]

Unlimited "healthy" fats.  (Read, olive oil is your friend)

This has worked wonders for me.
