Man Loses 37 Pounds in 90 Days on All-McDonald’s Diet

John Cisna claims to have lost 37 pounds on eating only McDonald's meals for 90 days.Cisna decided to begin his fastfood diet after watching Super Size Me.

Super Size Me is a 2004 American documentary film starring Morgan Spurlock. For 30 days, he ate only McDonald's food. The film shows how this diet changed his life in major way physically and mentally. He eats in the fastfood chain three times a day consuming 5,000 calories which is equivalent to 9 Big Macs.

Spurlock gained 24.5 lbs and an additional 13 percent on his body mass index. It took him 14 months to shed off those pounds. The film was made to show a picture of obesity in the U.S which is now a worldwide epidemic.

Cisna, a biology professor in Iowa, decided to modify the Super Size Me diet, consuming 2,000 calories only. He also exercised 45 minutes a day. His daily McDonald's meal included Big Macs, Quanter Pounders with cheese, sundaes, and ice creams. He got the food free of charge since he consulted a McDonald's store manager about his weight-loss plan.

After his 90-day weight loss challenge, Cisna dropped 37 pounds and lowered his cholesterol count from 249 to 170. Cisna added that anyone can enjoy any meal as long as it is within the calorie budget.

"We all have choices," he said told the Examiner.com. "It's our choices that make us fat, not McDonald's."

Cisna was not the only one who lost some weight with an all-McDonald's diet. McDonald's CEO Don Thompson claimed that he lost 20 pounds as well in 2013.

This weight-loss story will definitely give people a new look at McDonald's which have received lawsuits for making teens fat. Ruth Rhymes, mother of 15-year-old Gregory Rhymes, filed a lawsuit against the fastfood chain for making her son weigh 400 pounds. McDonald's described the case "baseless" and "makes no sense" saying it was the mother's negligence for not watching what her son eats.

The company was also remembered to be criticized by a nine-year-old girl named Hannah who asked why the company didn't sell healthy food.
