Zuckerberg told Fortune magazine in 2011 that he was only eating what he killed. The Facebook CEO said:
"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."
The next year, Zuckerberg announced that he was no longer sticking to his eat-what-I-kill dining rules.
