I listen to a podcast that also includes a fitness blog.
It's called http://cutthefatpodcast.com/
I like the podcasts, and I've even listened to several of them many times! They have a Facebook page that they're also very active on, as I have received feedback on my holiday success story.
Another one that is in the works of getting back online is Fat2FitRadio. Their archives are really good - I play them when I'm on the treadmill and in the morning on the weekends. They also have a facebook page with lots of good info on it.
Hope that helps!
