Not only that, but McDonalds is the official restaurant of the Olympics. Surely I'm not the only one who sees the irony in that?

There's irony. There's salad, chicken and green tea in McDonnald's as well (they just don't advertise it that much). You can eat that and stay fit.

Do they offer any of those things in the free McDonalds provided in the athletes village? They didn't the last time I saw it, but that was a few years ago now when they weren't focusing so much on healthier alternatives.

I guess you haven't looked at the fat content of their salads lately then.
