The Olympics of Advertising: Is it possible to survive using only “official” brands?

Ronald McDonald welcomes Five Ring Diet founder Terin Izil to London!

She cleverly called it “The Five Ring Diet,” and from the moment the torch was lit to kick off the 2012 Summer Olympics to the last few notes of the closing ceremonies, copywriter Terin Izil only ate, wore, lived and cleaned herself with brands that were official sponsors of the Games. She shared her daily quest on her Tumblr blog.

The challenging publicity stunt was staged as a fundraiser for Camp Promise-West, a camp the 28-year-old Chicago woman helped start for children and adults with muscular dystrophy and neuromuscular disorders. One of the camp’s amazing programs involves giving wheelchair-accessible hot air balloon rides.

For breakfast, Terin usually ate Chobani Greek Yogurt or Kellogg’s Corn Flakes (three-time Beach Volleyball Gold Medalist Kerri Walsh graces the box).  Procter & Gamble gave her a wide berth of choices of soaps, shampoos, toothpastes, skin care products and laundry detergent.  And Budweiser was there with commemorative bottles when she wanted to kick back and relax.
