Super Size Me

Three trips to McDonald's a day might be every little boy's dream. But the reality was nightmare for Morgan Spurlock, whose movie Super Size Me documents his one- month existence on fast food and its disastrous consequences. So, if it was so awful, why did he do it?  

This person is subjected to a risky experiment for a month eating only McDonald's products.
I think he wanted to prove to their own experience that these products are not food and have been for many years the cause of disease and diabetes in high-consumption countries. 

During the show he becomes the tests and his body are changing rapidly and suffer consequences. 

I think he managed to change the thinking of many people regarding their diet.
