Derek Nance, Kentucky Man, Has Eaten Only Raw Meat For 5 Years

Derek Nance has a bone to pick. Constantly.

For the last five years Nance has eaten only raw meat from animals he slaughtered.

He consumes almost the entire carcass -- the innards and fat included. The nearly exclusive flesh diet makes us queasy, but Nance believes it cured his own nausea condition.

Five years ago, Nance was vomiting constantly. He began to experiment with several diets, including vegan, before going to the other extreme, his own interpretation of the Paleo diet (also known as the caveman diet) that excludes almost anything without a heartbeat.

"I've physically gotten stronger and more physically robust," he told The Huffington Post.

And no expiration dates for this committed carnivore. Rotting meat is OK. Someone else's rancid is Derek's USDA choice because it's probiotic ^[1] , he told Vice.com in a story that sparked viral interest ^[2] in the 30-year-old Kentuckian.

Mom and Dad don't approve, but his vegetarian girlfriend understands. A father of four, he also admitted to HuffPost that his eating habits "kind of led up to" his previous marriage ending in divorce. It's complicated.

Nance's unusual meal plan (lamb is his preference) has been documented from time to time over the past few years. A 2012 YouTube entry (above) shows him cracking open a lamb leg ^[3] that's been aging in the fridge and sucking out the marrow. "I wash it all down with a good cup of blood," he says, and does so.

But perhaps our favorite raw video comes at the beginning of "Extreme Animal Obsessions,"^[4] a 2010 short film posted on Vimeo. Spotting rabbit roadkill, Nance slices a piece and eats it right off the knife.

At least one dietitian has a beef ^[5] with Nance's lifestyle, even if he occasionally indulges in an avocado or coconut. "Although in theory this may seem like a sensible diet, particularly when removing sugar and salt, it has eliminated several food groups like dairy and grains, which provide essential nutrients such as calcium, vitamin D, magnesium and phosphorus in dairy and B vitamins, fiber and antioxidants in grains," Joy Dubost of the Academy of Nutrition and Dietetics told HuffPost in a previous report on the Paleo diet.
