Tonight... "On the Record" is preempted so that we can bring you a special edition of "Breaking Point: Danger and Diets."

Our special this evening is another in an important series of investigative documentaries brought to you by the staff of the Fox News Channel.

In this one-hour report we'll examine the hidden dangers behind some of our country's diets. Did you know that some of the most effective diets are also the most dangerous? The results can be dramatic, but they can also make you sick or even kill you.

Join us this evening at 10 p.m. ET and 3 a.m. ET for this edition of "Breaking Point."

And don't worry, Greta will be back with "On the Record" tomorrow night at 10 p.m. ET!
