Glenn Reynolds posted a review of Supersize Meearlier today.
The movie has an interesting premise, but as CEI fellow Soso Whaley shows in her one month journey of eating nothing but Mickey D's its just junk science. John Stossell's Give Me A Break is going to discuss her diet over that time and how by making informed menu choices - like not supersizing her order - she was able to lose not only 10 pounds but drop her cholesteral as well.
The CEI web page has pdfs of all her receipts and calculations of the calories involved. Good reading.
