I found a very good article about a research study with mice who were put on a fast food diet and after just 4 weeks they developed Fatty Liver disease and Type II Diabete's.
Amazing how simular this study is to the guy on the ''SuperSize Me'' Micky D diet for 4 weeks who showed the exact same diseases as the mice did.....
