It is people's choices on whether or not they get fat, however there's a few things that makes it more pleasing: 1. Price: fast food is so much cheaper than preparing food and so much easier. 2. Time: many people don't have time to make their own food so they get fast food. 3. Amount: in this experiment, he ate only 2,000 calories a day. That really wouldn't be THAT hard to do with McDonald's food. A couple of burgers, some fries, and soda and you're at 2,000. However this doesn't fill you up at all which is why people eat more, the guy must've been damn near starving the whole time if that's what he ate. (I'm not saying, "oh eat as much as you can" I'm saying fast food is filled with phony ingredients that take a lot more to fill you up.) 4. Exercise: this experiment is pretty much nullified by the exercise thing. That plus eating only 2,000 calories a day, we burn calories all the time. And with this being trans-fats they were probably easier to burn, which would explain the weight loss and lowered cholesterol. Most people don't exercise because they don't have time to or they are lazy. Which is [i]their[/i] choice. Summary: basically what I'm saying is that there's a lot of biases in this experiment, enough for it to be nullified IMO. I'm not a scientist or anything but this automatically doesn't make McDonald's good or fat people 100% responsible for their problem. The fast food industry is an absolute disgusting industry and I have avoided at all costs eating at any. [spoiler]inb4Opisfat I weigh 145[/spoiler]
