Favorite health/weightloss/better life tv show?

I don't necessarily mean as inspiration, but if that's why you watch it, that works too!

For laughs, I love watching "You Are What You Eat." Gillian McKeith is a terrifying woman and I wouldn't want to meet her in a dark alley with a doughnut.

Also "Supersize vs Superskinny", though the new episodes don't have the large clear tube where they'd put the whole week's worth of food in, and that was the best part of the show for me.
