Janet Jackson is planning to write a book about weight loss, having experienced yo-yo weight throughout her life.

The singer, who is planning to tour her latest album Discipline this year, is co- writing the book with her nutritionist, David Allen.

Jackson says that it was her fans asking how she managed to lose weight that inspired her to write it.

"Everybody asks me–men, women–how did I do it?" she tells Billboard. "Even young people will come up to me and they have an issue with their weight and they're very concerned. So it's basically my journey; it's not just this sterile, weight-loss-and-how-to-do-it book, but my journey even from when I was a kid…being an emotional eater. It takes you through those moments in my life up 'til now and what worked for me."

The as-yet-untitled book is expected to be released towards the end of the year.
