I've done a month of exact opposite. Sometimes I didn't eat either. Catch up on WWDC, wrote some cool hacks, update some libraries, write some tests for someone elses library, do some pull requests. Lunch itself is a waste of time, adding co-workers that might eat slower than you where social conventions requires you to stick around (because they are kind enough to do so). I rather just avoid that whole mess. Besides, lunch was invented so I could watch WWDC in peace. I am also lucky to work in a place where no one gets upset or questions it. I actually like the company of my co-workers, but lunch is me being productive.
