If you have a craving for a Big Mac, you may want to double that order according to a dietitian.

While McDonald's may be a rare 'treat' for some, you can balance your diet a bit better when going through the drive-thru of the Golden Arches.

Most of us can agree that McDonald's food doesn't taste as good as it used to when we were kids- especially their fries.

McDonald's reportedly stopped using beef tallow to cook their fries in the 1990s. The switch from beef fat to vegetable oil changed the way the fries tasted, and they haven't been the same since.

The switch was made after fears over cholesterol fats rose from health practitioners.

While the average order at McDonald's consists of a Big Mac, chocolate shake and large fries, a nutritionist advised that you're better off to double down on the burgers.

While the fries and the milkshake are delicious, dietitian Emily Field says having two burgers will offer more protein and balance your blood sugar, while reducing the amount of fat and carbs you take in when you eat 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 the swap would increase calorie intake, Field cites research published in the journal of National Metabolism that suggests balancing macro-nutrients in a meal is critical to balance blood sugar.

The macro-nutrients include fats, carbohydrates and proteins.

While the burger does contain carbs in the bread, fat and protein from the beef, your favorite deep-fried side-dish just provides fat and carbs. Your body needs the protein to help break down the carbs and "buffer against sharp dips and spikes in insulin levels".

Eating a meal that balances protein, fat and carbs will also help to regulate your sugar level balance, and help you stay full for longer.
