I don't know if you've seen the movie Super Size Me, but I can say that it definitely changed my perspective on fast food, health, and weight loss.
The movie actually came out in 2004, and the goal of the movie was to document what would happen if someone at all of their meals at McDonald's for 30 days.
Yep, the Director and Star Morgan Spurlock at breakfast, lunch, and dinner from McDonald's every day for 30 days.
Needless to say, he gained a ton of weight and started experiencing failing health.
But, one thing that really struck me was one of the bonus videos in the dvd.
In one bonus video, Morgan Spurlock takes hamburgers and fries from McDonald's and hamburgers and fries from a local diner and puts them in glass jars to see how long it would take for them to get moldy.
The burgers look pretty nasty after 2 weeks, but the French Fries from McDonald's look brand new. Even after 10 weeks the French Fries look brand new.
Check out the video for yourself...
The moral of the story is that there are so many preservatives (chemicals) in the fries that they don't decompose.
When food is processed it loses it's nutritional value and also causes adverse health reactions.
If you're trying to lose weight, you definitely should avoid eating fast food and highly processed foods on a regular basis.
