What I’m about to say may shock you. Fast food is fattening.

Now, you may be thinking to yourself, “Where have I been?” But don’t worry, you are not alone.

Recently, two teenagers in New York filed a lawsuit against McDonald’s. They claim that the fast food joint made them fat.

After years of eating there almost daily, the girls, 19 and 14, now weigh 270 and 200 pounds, respectively.

According to doctors, each girl is considered at least 80 pounds overweight.

They claim that neither they nor their parents had any idea how fattening the food was.

After all, they reason (in what is not at all the weakest argument ever), that McDonald’s never advertised that the food was not fattening.

Now, I’d like to generalize and say that one would have to be a moron not to know — or at the very least, suspect — that greasy, fried foods are not exactly health food.

But I won’t. I won’t even ask how anyone could miss the dozens of newspaper, magazine, and television news spot stories that remind people every day about the detrimental effects of fast food consumption on health.

What I’m wondering is did these girls, at any point along the way of their weight gain, question the food they were eating?

I know we all have a tendency to blame a few extra pounds on water weight, but these girls long- surpassed the point at which they could do that.

They got to be 80 pounds overweight before they even thought to look at the fat content of the food they were eating.

Don’t get me wrong: I’m by no means criticizing these girls for being overweight or criticizing their eating habits — that’s not the issue, considering they (somehow) had the impression fast food has nutritional value.

The issue is that the girls never bothered to find out what was in the food they were eating and are now holding McDonald’s accountable for their own ignorance.

Or is McDonald’s to blame after all?

Shame on you, McDonald’s. You greatly overestimated the common sense of the general population and for that you will pay.
