“I only eat meat I kill.”

“I just killed a pig and a goat.”

Props, Young World Ruler…

Mark Bittman and Michael Pollan and Alice Waters and Jamie Oliver would approve:

“I’m eating a lot healthier foods,” Mr. Zuckerberg told Fortune. “And I’ve learned a lot about sustainable farming and raising of animals,” he says. “It’s easy to take the food we eat for granted when we can eat good things every day.”

And, in a message to Fortune:

This year, my personal challenge is around being thankful for the food I have to eat. I think many people forget that a living being has to die for you to eat meat, so my goal revolves around not letting myself forget that and being thankful for what I have. This year I’ve basically become a vegetarian since the only meat I’m eating is from animals I’ve killed myself. So far, this has been a good experience. I’m eating a lot healthier foods and I’ve learned a lot about sustainable farming and raising of animals.

I started thinking about this last year when I had a pig roast at my house. A bunch of people told me that even though they loved eating pork, they really didn’t want to think about the fact that the pig used to be alive. That just seemed irresponsible to me. I don’t have an issue with anything people choose to eat, but I do think they should take responsibility and be thankful for what they eat rather than trying to ignore where it came from.

More from Fortune:

“I was surprised by how many of my friends have interests in some of the areas I’m exploring in such diverse ways. Many are vegetarian, some enjoy hunting and some even farm. My girlfriend is my main partner in this, though, since we eat the most meals together.”Zuckerberg’s learning curve has been evolutionary: moving from sea creatures to land animals. His first kill was a lobster, which he boiled alive. He says it was a difficult kill, at least emotionally. He had an entirely new feeling once he took a bite: “The most interesting thing was how special it felt to eat it after having not eaten any seafood or meat in a while.”

After the lobster, the next animal to fall at his hands was a chicken. What’s next on this journey? He’s told people that he’s interested in going hunting.

Zuckerberg says the new kill-what-you-eat diet hasn’t changed his frequent restaurant goings; he just limits himself to places where he can eat vegetarian…for the rest.
