The first diet book from Hungry Girl cookbooks author Lisa Lillien, The Hungry Girl Diet, hit #1 on Amazon's bestseller list on February 26, a month before the book's March 25 on-sale date. The upswing in preorders followed a promotional email sent to the Hungry Girl subscriber list of 1.2 million. The book stayed at #1 for more than a day.

“It’s so exciting to see this sort of overwhelming reaction to The Hungry Girl Diet so far in advance of its sale date,” said Lillien. The book has announced first printing of 175,000.
