Here's a review which says it better than I could have:
A smartly-written novel of two women starting at opposite ends of the scale--and finding compromise and friendship in their journey towards 150 pounds. In the fast paced life of blogging, two women stand out: Alexis Allbright, of Skinny Chick (100 pounds), and Shoshana Weiner, who writes Fat and Fabulous (225 pounds). Both have over five million loyal readers. Both are hungry for success. But the similarities stop there.
With over 100 pounds on the scale separating them, weight isn't their only difference. Alexis is a loner who is so bitchy the only person who can stand her company is her gay best friend Billy. She gives neurotic New Yorkers a run for their money with her strict daily workout routine, and weighing of food. Shoshana is Alexis’s opposite. Living in Jersey with rowdy roommates, she is someone who “collects friends,” as her mother puts it; and treasures a life of expanding circles...and waistlines.
When both appear as panelists on a popular talk show, their lives intersect in ways neither could have imagined. In turns comedic, heartwarming--and familiar to any woman who's ever stepped on a scale--Alexis and Shoshana realize they have far more in common than either could have possibly imagined, and more importantly, something to offer.It is a work of fiction. The blogs do not exist (I googled them) but it really spoke to me about this weight loss journey.
One day I hope to be able to write the same title to a post on my blog for real!
