If you feel like you've been having a lot of Maccies recently - it'll probably never compare to the amount David Geyer consumes as he eats a McDonald's burger every other day and has done so for over two decades.
On top of this, David also loves to buy the merch and has spent an estimated £4,300 (€5,000; $6,000) on things such as trainers, clothes and socks.
The gardener even has a tattoo of a juicy burger on his leg and his home in Bergheim, Germany, features a makeshift McDonalds sign and a menu on his living room wall.
David, who has eaten over 4,360 burgers, said: "McDonald's has been a huge part of my life for so many years.
"It felt right to get a tattoo last July as the fast-food chain has become apart of my identity."
Rather surprisingly, David never orders the same meal over and over again like I suspect many of us do, but he does have his favourites.
He explained: "I never order the same meal over and over again because then it would get boring. But a Big Tasty Bacon meal with fries is to die for."
David has no complaints about the menu but tends to avoid the Filet O Fish and vegan options.
He said: "I am always hungry for a McDonalds and often can't refuse a burger when I drive past.
"People may think I am absolutely crazy. But it's not just about the food; it is about the people, the employees and the memories made in a McDonalds that make it special.
"I will always remember my first visit during the spring of 1997. It was an amazing treat and I knew Mcdonald's was going to be apart of my life forever." Didn't we all, mate...
When David landed his first job in 2005, he recalls spending more time in McDonald's than home. He said: "My real fascination began when I started making my own money.
"I sat more in McDonald's Restaurant than at my mother's dining room table. At one point, I was eating a Maccies eight to 12 times per week."
David has a cabinet dedicated to McDonald's memorabilia ranging from Coca Cola glasses to trainers and bags. He said: "I am an easy person to buy for at Christmas as I love anything McDonald's related.
"I have received a makeshift McDonalds logo sign which is on my living room wall. It is next to a photo of the menu which I purchased on eBay. I have a few pairs of Nike trainers which have been personalised and McDonald's laces to match.
"I have spent around €5,000 on merchandise. It is hard to put a number on how much money I have spent on food. I imagine it would be about £34,000 [€40,000]. Every cent is worth it!"
