For most of us looking to avoid gaining weight, one of the key rules is to keep takeaways to a treat we indulge in once or twice a week.
Not so for Brian Northrup, who's made a point of proving you can stay healthy whilst eating a Domino's pizza every single day of the year.
He's managed to maintain a healthy weight and even kept his muscles toned, whilst scoffing a takeaway every night as part of an Instagram project he calls the 'PIZZAPOCALYPSE'.
When LADbible talked to him about the project he said that one of the main points he had to prove was that diet isn't everything when it comes to staying in shape.
He told us: "The real ambition of the series had less to do with cheese and sauce, and more to do with sharing the mental framework I've used to achieve the level of fitness.
"Too often have I heard trainers, fitness 'gurus' and even doctors tell people: "You can't outwork a bad diet." I believe all of those people vastly underestimate what is possible through hard work.
"Just look at Michael Phelps; the man became arguably the greatest athlete in the world on a diet he claimed consisted of pizza, as well as a lot of other 'bad' foods, on a daily basis. I think a good diet is highly dependent on the individual and it is more important to focus on making sure your diet includes everything you need, than what you need to cut out."
Although this might all sound a little bit suspicious, his fundamental point is that if you're willing to put in the hours in the gym then you can still eat all the food you enjoy. He also thinks that that sometimes we can get a little hung up on limiting our calorie intake, which isn't always the best way to go about improving our lifestyles.
He makes sure to have regular health checks and insists that his sodium intake and cholesterol levels are both within a healthy range.
"Burning off calories is not my reason for working out, to me that's putting the cart before the horse," he says. "Basically, I eat more in order to work out more - as opposed to working out more so that I can eat more.
"That may seem like a silly shift in semantics, and maybe it is, but if so it's a silly shift that has lead me from being unable to run from one class to another for 60 seconds straight, to running double digit miles daily."
If you're wondering what his fitness regime looks like, he does an hours or so of full body lifting sessions 3-4 times per week, and around 20-30 miles of cardio each day, which takes between two to three hours every day.
