After dining solely at McDonald's for 90 days (here's a handy timeline of everything they've ever served), an Iowa science teacher lost 37lbs and lowered his cholesterol, like an alternate universe Morgan Spurlock. With the help of his students, John Cisna came up with a meal plan that adhered to federal dietary suggestions, like the recommended 2000 calories a day, plus the healthy allotments of carbs, fats, proteins, and cholesterol.
Receiving his 90 days worth of Mickey D's grub fo' free because the owner was so intrigued, a typical day's intake included two egg white McMuffins, oatmeal, a salad, and a value meal, plus a daily 45min walk. Cisna could eat whatever he wanted off the menu (Big Macs! Sundaes!) as long as it kept to the nutritional and caloric limitations. Perhaps this'll soon be added to the great canon of fad diets.
