Here is a site that I think looks good and conveys its message: http://www.hungry-girl.com/

This blogger, Lisa Lillien, is food-obsessed, yet she also cares about health and fitness. The image of a girl biting into a plate emphasizes that indeed she's hungry, but punny subcategories such as "Chew the right thing" and "Top Ate," along with "Weekly Weigh-In," show that she cares about health and nutrition as well. And the martini glass shows she also wants to have a good time being healthy! This is clearly not a site about deprivation; it's a site about intelligent indulgence, and I think that shows in the overall look of the site.
