Apparently I wasn't clear. I don't mean that if someone sees a McDonald's commercial, then they always go out and get a Big Mac. What I meant was that we are bombarded by advertisements since we were children and when some people are hungry, the first thing they think is fast food, because you don't see, for example, homemade pasta with zucchini, chick peas and galic on TV.
You also misunderstood my "healthy choices" comment. I was trying to think like someone who was overweight and making excuses as to why they are still that way. When it comes to my diet, I'm vegetarian and try my very hardest to eat locally grown, organic food. I definitely know there are healthy choices available and many healthy meals are very easy to make. Mr. I-Drive-Everywhere-I-Go might not know how easy it is to eat healthy though. And you know what, not everyone is comfortable cooking, some would rather have others make their food for them. I also know some people that when you mention healthy diet, they think all you eat is salad. Not everyone has the same education when it comes to food.
