TL;DR: Exercise self-control, but respect others and don’t set them up to fail. Respect all needs.
I think it’s more than fair to request that such snacks be limited to the break room, and that for any organized activities, healthy alternatives be provided.
I don’t have a particular problem with temptation myself, but it’s taken a fiar bit of training and an aweful lot of “thanks, but no” to get there.
I also take preemptive action by having my own healthy alternatives available: whey powder, cottage cheese and Greek yoghurt, carrots, fllax, and oats.
Truth is there’s a lot of social pressure to conform, and a lot of folks struggle with this. And strength trainers/atheletes/fitness buffs aren’t the only ones dealing with this. I’ve been at offices where lunch was regularly catered (it’s typical in Silicon Valley, less so if you’re in San Francisco where walkable alternatives exist), and the lunches were very frequently disasters.
That said: I started my fitness kick at a large campus-based job site which had a gym (minimal freeweights, though some), and cafeteria with a pretty good salad bar (salad + chicken FTW). So sometimes work can be conducive to good living.
Biggest issue is less the food and presence of it, but the “just have one” ribbing that can go on. I have a very practiced “Thanks, but no” response, which gets much colder if it has to be repeated. Most people know better than to push the issue. There is a very fundamental role of food as a bonding and sharing device, and it’s deeply ingrained in people. So yeah, there’s a lot to overcome.
Given the posts here about habits, social circles, sabateurs, etc. (just today, Shelb’s got a spill “The Company You Keep” (http://www.T-Nation.com/strength-training-topics/660), and Shugart’s “Sabotage” article is a classic I’ve referred people to multiple times: (http://www.T-Nation.com/readArticle.do?id=636910).
There’s also what we know about how additictive certain food choices are – soda, fast food, the sugar + fat + salt combination noted by David Kessler in The End of Overeating. While it’s good and fine to push personal discipline, it’s helpful to keep in mind that some deviously smart people have been working for a long time to make bad foods highly attractive.
I’ve got no problem taking potential pitfalls and minefields out of my environment. A big part of my success has been taking free will out of the equation by NOT having bad food choices around, by training myself to think of them as poison (which is why I get very insistant and firm when “friends” push that shit on me), and by making the good stuff a matter of habit.
Suggestion: run a poll. See who feels one way or the other. Request healthy alternatives. Have a “no food on the floor” policy in the office (your IT staff will love you) if that’s what it takes – closed packages and out of site at the very least. And if it comes down to it, just to piss everyone off, “sensitivity training” as to dietary requirements and choices.
