The Big Mac was introduced in 1968 and features two all-beef patties on sesame seed buns with cheese, pickles, onions and a special sauce.
"This one is a biggie for me, something I have been looking forward to".
Gorske claims to have eaten two Big Macs nearly every day since 1972. Gorske's approach has been much more measured than that over the years, but still might seem excessive to some.
Gorske typically eats 14 Big Macs each week, purchasing them in bulk and microwaving them at home, according to the Guinness book.
Gorske says he has OCD, which has led him to catalog thousands of receipts, wrappers, and containers over the course of more than four decades. He keeps almost everything, although he lost about 7,000 items when a tornado ripped the roof off his house. Think a stay-cation package at mom's favorite hotel where she can have a few cocktails and lounge by the pool but rather than spending on them, most moms surveyed said they'd like to spend a real day or two off.
Gorske said he is still in good health despite the fact that the burgers are far from healthy.
He continued: "People make fun of me, but it never bothered me", Gorske said. In case you're wondering, he says his cholesterol and blood pressure are normal - and he weighs five pounds less than he did 5,000 Big Macs ago.
Fair play then, if it keeps him happy. Before her death, she asked Gorske to skip eating a Big Mac on the day she died, in remembrance of her.
He hasn't looked back since then. Gorske said he plans on keeping his routine going for another 14 years to get to 40,000 Big Macs eaten.
