Bec Hardgrave: Fitness influencer reveals how to order a 'mini Big Mac' at McDonald's 

A fitness coach has revealed how she orders a mini Big Mac in McDonald's - and it's cheaper and has less calories than the original.

Bec Hardgrave, 27, from Brisbane, 'heard a rumour' she could get a mini Big Mac by ordering a cheeseburger and asking for it 'like a Mac'. 

This time, however, it  has one beef patty and does not include a bun in the middle.

'This is the mini Mac,' Bec said as she recorded a TikTok with her mum where they tried out the burger.

She said that if McDonald's staff don't know what a cheeseburger 'like a Mac' is, you can just order a cheeseburger, remove mustard and ketchup, and add lettuce and Big Mac sauce.

Bec had 'heard a rumour' you can get a mini Big Mac by ordering a cheeseburger and asking for it 'like a Mac'. She tried out the menu hack with her mum (pictured)

Altering a cheeseburger to make it into a Big Mac should only increase the price by $1, bringing it up to about $5.50.

The fitness influencer said the dish is perfect for when you're just feeling 'like a little Mac' instead of having a large burger. 

'If you don't want the whole Big Mac you can get it in a cheeseburger version, and it's way cheaper,' she said. 

Bec was very impressed with the dish.

'This is actually so yummy,' she said as she was eating it.

Her mum had never tried a Big Mac before, and wasn't convinced, but she did say the sauce was nice.

Bec's fans were very impressed with the Macca's hack.

'I wish this was a regular menu item,' one man said.

Another had been ordering the dish 'for years'. 

Several people had different nicknames for the dish, ranging from 'jr. Mac' to 'son of Mac'.
