Although our average order at McDonald's is a Big Mac, chocolate milkshake and large fries, a nutritionist has advised Business Insider UK that you're actually better off ordering two burgers instead of the sides.

While the chips are delicious and the milkshake is arguably a must, dietician Emily Field says having two burgers will offer more protein and balance your blood sugar, while reducing the amount of fat and carbs you'd be consuming if you had the fries.

"By swapping the fries for a second burger, you're nearly doubling your protein intake while reducing the amount of fat and carbs you're eating", she explained to the publication. "Since fast-food is already high in fat and carbs and pretty low in protein, this simple switch could help steady your blood sugar levels."

While a burger typically contains carbs (from the bread), fat and protein (from the beef patty), deep fried potato chips just provided a lot of fat and carbs, and your body requires the protein to help breakdown the carbs, and "buffer against sharp dips and spikes in insulin levels".

Also, ating a meal that balances protein, fat and carbs will also help to regulate your sugar level balance, and keep you feeling fuller for longer.

As if you needed another reason to order two burgers.
