Former Iowa science teacher John Cisna, who says he lost 60 pounds on a 6-month regimen of McDonald's food and daily walks, has sparked outrage among public health advocates for taking his story to 90 US schools on the chain's dime.
Among other things, his program includes a 20-minute documentary "540 Meals: Choices Make the Difference" and a discussion guide for teachers, both of which were edited by McDonald's.
Critics say the program is a new attempt by McDonald's to hook youngsters on unhealthy food. For example, Cisna says in the video that careful planning allowed him to eat French fries nearly every day. (Ed. Note: Yuck.)
