Here are the numbers of Ann Galardi's life:

She is 16.

And a size 17.

Her perfect mother is a size 6.

Her Aunt Jackie is getting married in 2 months, and wants Ann to be a bridesmaid.

So Ann makes up her mind: Time to lose 45 pounds (more or less).

Welcome to the world of informercial diet plans, wedding dance lessons, endless run-ins with the cutest guy Ann's ever seen—and some surprises about her not-so-perfect mother.

And there''s one more thing—it''s all about feeling comfortable in your own skin—no matter how you add it up!
