A lot of people would vouch for the effectiveness of watching the Super Size Me
video. Consider it a cheap two hour weight-loss therapy and motivational session. It could turn anyone off junk food. It's a scary portrayal of what can happen to your body and your mood if you subsist solely on junk food for thirty days.
Filmmaker Morgan Spurlock put himself through this test on film and ate three McDonald's meals a day. In less than a week he was already experiencing some serious negative effects including a lot of weight gain.The documentary has won many prestigious awards and was nominated for an Oscar.
The DVD
was released a year and a half ago and has great reviews at Amazon. It costs $18 but there are several used copies available there as well for $7.99.
