LOL, both of those documentaries were complete jokes.
First of all, I didn't say that everyone should be eating fast food or junk food for every single meal. I said that eating fast food a few times a week isn't bad as long as the other foods you eat are nutrient dense.
Secondly, Super Size Me was a documentary about a guy who ate McDonald's 24/7. Not only that, but it's been conclusively proven that that guy had to lie, because he had to have consumed waaaay more calories to have gained the weight he claimed to gain. He was eating a lot more than he claimed in the documentary.
Thirdly, Food Inc. is a complete joke because it bitches about the one thing that keeps a few billion people alive: factory farming. Is factory farming as healthy as pasture farming? Of course not. But if you eat lean factory farmed meat and throw in some krill oil, you basically get the same health benefits you would from eating pasture-raised meat at half the cost.
And then, of course, Food Inc. was bitching about HFCS, which honestly is healthier than sugar, as it's lower on the Glycemic Index, and because it's sweeter, so foods that have HFCS have less calories than they otherwise would have if they had sugar in them.
So, use some common sense. Fast food is high in calories and low in nutrients. So don't eat it for every meal, but as long as you have nutrient dense food around your fast food meal you'll be fine. Eating it a few times a week won't kill you!
