When probed on what breakfast the Monarch would be tucking into this morning ahead of the Trooping the Colour, Mr McGrady replied: "She sticks to a routine so she'll start with her regular breakfast of cereals, there will be no fry-up."
People have speculated the Queen's diet for years, pondering on what Her Majesty indulges in daily.
The conversation arose in recent weeks on social media, following the crowning of a lemon and amaretti Swiss roll trifle as the official pudding for the Queen's Platinum Jubilee.

Mr McGrady divulged that the Queen is partial to a chocolate dessert, stating: "One thing I can say is the Queen loves chocolate deserts, anything with dark chocolate."
The Royal chef spent years cooking and preparing meals for various Royals, and fondly reminisced an exchange he had with the Queen: "It doesn't get better for a royal chef than the Queen looking through the window and thanking you."
In a previous interview with HELLO! Mr McGrady said the Queen would receive a red leather-bound book every week, which included a vast selection of menus and recipes which are written in French.
He added: "The chefs would pick the menus and she would put a line through the ones she didn't want. Sometimes she'd put a line through it all and put something different - like if she was having dinner with Prince Andrew, his favourite was Crème Brulee with Sandringham oranges."
The Queen is due to appear on the palace of Buckingham Palace for the RAF flyover at 1pm today.
Jubilee celebration will commence this morning, when the Queen's Birthday Parade will leave the Palace for Horse Guards Parade where the Trooping the Colour will commence from 10am.
