We asked viewers from across the country to write in and tell us why they wanted to take the Canada AM 'You: On a Diet' Challenge, which included a one-on-one consultation with best-selling author Dr. Michael Roizen. Three lucky ladies were chosen.

Over the next few months, these women will be working hard with Dr. Roizen and his team to whittle away their waistlines. Caroline, Suzanne and Tami will update us daily on their progress through blog entries which you can read below, chronicling their triumphs, their temptations and ultimately, their long-term weight loss goals.

If you have questions or comments for our winners, or if you just want to cheer them on, please email hsherman@ctv.ca
