Iowa biology teacher John Cisterna accepted a bold challenge: eating every meal at McDonald's for 90 days. The outcome was impressive—he shed 17 kilograms while improving his health markers.
Balanced Menu Planning
John enlisted his students to craft a nutritious McDonald's menu. Breakfast featured oatmeal with skim milk and Egg White Delights. Lunch consisted of fresh salads, while dinner included classics like a Big Mac or cheeseburger, finished with a small ice cream.
Daily Exercise
A key factor in his success was incorporating 45-minute daily walks—John's first consistent exercise routine.
The Power of Choices
After 90 days, John lost nearly 37 pounds (17 kilograms) and saw his cholesterol levels drop significantly. His experiment proves that maintaining a 2,000-calorie daily limit allows flexibility—even at fast food. "McDonald's doesn't make us fat; it's our choices that do," John notes.
