Here is what I mean. Lets say socioeconomically, you are sitting pretty. Why cook your own food when there are hundreds of places within a quick drive that will cook for you? Not only that, but they will clean up the mess. The only problem is, these establishments, better known as restaurants, want you to come back. So what do they do???? They make the food taste great. Lots of sugar, fat and salt. Sadly, yum yum = big Tum Tum. You do not have control over what goes into the food when you eat out. Believe me when I tell you that 99% of the time you would be appalled at what goes in to make the food taste good. Eat out enough, you will gain weight.
Now if you are too poor to eat out, then you must look for the cheapest source of food out there. You will find this in processed food located in the middle of the food store. If you have to take it out of plastic or cardboard, then its is not good for you. Also, it usually has high calorie, cheap sweeteners in it like High Fructose Corn Syrup (HFCS). This is why the poorest people in our country are the most overweight and have the highest incidence of Diebetes.
Moral of the story….be middle class
