But Colin Moore managed to lose a whopping 10 stone after he got a job at McDonald's.
Before he worked at the chain, the 27-year-old from Durham loved burgers and adored feasting on two of them with chips for lunch.
With this, pizza for dinner and crisps and cola throughout the day, Colin crept up a dangerously heavy 24 stone.
While he was waiting for gastric bypass surgery, however, he managed to find work at McDonald's - which turned out to be the best diet he could have asked for!
After being surrounded by junk food and its smell all day, he turned to fruit, salad and chicken and managed to slim down to 14 stone.
He said: "Working at McDonald's put me off eating burgers, helping me reach my final goal."
We bet he's loving it!
