Query: still another answer to everything

Atkins has revised and updated his old diet to fit the latest trends. I'm suspicious of books that claim to have the definitive answer--there are too many conflicting research claims floating around these days to know what's really the Truth. I had hoped to find Atkins had modified his approach, but he hasn't and it's just too extreme for me.
