If you want to actually stomp on him verbally, than bone up on the science. I'm fairly well-read on the matter of diets, and I can more or less stomp on any argument if I choose to.
But I usually don't choose to. Most people don't want to hear it, and if you start babbling about diets too much you sound no better than a fundie wanting to convert everyone to your cool thing.
That said, if there's a discussion going on, and I'm hearing bullshit, I'll call the person on it. I don't sugarcoat (oh, wait, I'm primal -- I should say "honeycoat") and I tell them when I think something (like the "Blood Type Diet") is bunk. But I must reiterate: I don't do this unless I perceive someone actually wants to discuss it. And I don't always use that moment to talk about how awesome paleomal has been for me. I let my cholesterol results and body shape do that.
And honestly, I think subversive is the way to go. Be the change blah blah blah. Alternately, take yummy photos of your food:
But what do you eat? - a set on Flickr
That's what that photo set is for. And it feeds into my Facebook status every time I update it....

My job had a bake sale to help diabetes research.
I don't even know what to say to that. I donated 5 dollars and told them I didn't want anything. They tried to force me to take a few items. It was mostly baked bread, cookies, cupcakes, and cake.
This morning was "free coffee and donuts" morning, which happens once a month in my work building (apparently so that everyone in the building can get to know each other). I bypassed the event, I'm not a great fan of donuts and eugh the sugar + following insulin spike
