Fitness and Nutrition website

There's a dizzying number of blogs out there, all tempting us to procrastinate at work. But it's hard to know which sites are truly trustworthy, entertaining, informative, and Pinnable. So we went ahead and scoured the blogosphere to narrow it down to these standouts. They're keeping it real (no #fitspo here), using science to back up claims, always staying positive and inspiring, and delivering content we can't stop reading and sharing.

We went after blogs that address interesting and timely issues and feature useful, upbeat (but never in an annoying way) posts that reflect Greatist's mission of making healthy living a little bit easier and a lot more fun. We then looked at a variety of factors, including frequency of posts, comments and engagement with readers, number of social media followers, and design quality to narrow down the list to these rock stars. For more, check out last year's list, and tweet @Greatist to let us know who we should consider for next year!

Note: Blogs are arranged in no particular order. The first entry in each section is no better than the last entry.
