Each Big Mac has 600 calories and each parfait has 30 calories.
Assuming he eats only this in a day, then he's a very low-calorie diet
-1280 calories. With the walk he does, that would explain why he's not
obese.

US man has eaten 23,000 Big Macs since 1972

Sep. 10, 2008

FOND DU LAC, Wisconsin - Don Gorske says he has eaten 23,000 of
McDonald's Big Mac burgers in 36 years.

The Wisconsin man said he hit the 23,000 milestone last month,
continuing a culinary obsession that began May 17, 1972, and is fed by
his obsessive-compulsive disorder.

"I enjoy them every day," said Gorske, 54. "I need two to fill me
up."

Gorske has kept every burger receipt in a box. He says he was always
fascinated with numbers, and watching McDonald's track its number of
customers motivated him to track his own consumption.

Despite a diet some would call unhealthy, Gorske says he keeps himself
in good shape. He says he's 6-foot-2 (1.89 meters) and weighs 185
pounds (84 kilograms), and walks as many as 16 kilometers a day.

He used to order fries every day in the 1980s but began to cut back in
the '90s, now eating them about once a month. He eats two Big Macs,
which each have two beef patties, cheese and a special Mac sauce,
along with two parfaits a day. Gorske has written a book about his
experience.

"Sometimes people call me a freak but it doesn't bother me. I just say
respect people as they are," he told The Associated Press. "I just
want to make sure people understand I'm not going to change."

He can instantly recall the eight days in which he failed to satisfy
his craving. One was in 1988, the day his mother died, to respect a
request she made.

"I made a promise to her and I always keep my promises," he said. "I
also promised her I wouldn't cut my hair and in 20 years I haven't."

He twice failed to grab a Big Mac because of his job. A prison worker,
he said a number of work emergencies kept him on the clock past
midnight so he recorded those days as missed days.

Three other times he was traveling and couldn't find a McDonald's. He
also went Big Mac-less on the U.S. holiday of Thanksgiving in 2000,
and during a 1982 snowstorm that prevented a local McDonald's
franchise from opening.

"That's when I started a habit where I kept them in the freezer," he
said. He keeps one or two burgers on hand but increases his inventory
to four to five during the winter.
