My favorite protein powder is actually rice-based. (Go figure!) Eades says it's OK to use rice protein, though he mentions whey is the most perfect kind. (Problem is, whey is known for getting into the system quickly so while it's a great replenishment right after exercise for athletes it can leave you hungry.)

The rice powder I get is this one - very light and no weird tastes, still filling: Nutribiotic - and it's 55 cals per tablespoon with 0.3g fat, 1.8g carb and 12g protein.

Bought the 6-week cure book just now online. I think I love e-books.
