(CBS) If you’ve ever wondered how French women stay slim while eating cheese, bread, and drinking wine, the book “French Women Don’t Get Fat” has the answers.

Author Mireille Guiliano visits The Early Show to share slimming secrets French women have known for years.

The percentage of female French smokers is not much greater compared to the number of Americans who smoke according to the American Cancer Society.
