Now, does he have an enormous breakfast that starts at seven and finishes around 11? Who’s to say?

Does he likely dine on a feast prepared by a hundred chefs and served on a table larger than most people’s homes? I daren’t even suggest such a thing.

In any case, under the advice of his doctors, King Charles began eating lunch in an effort to keep his strength up.

So, now the monarch eats half an avocado daily to sustain him until his banquet dinner.

Only half an avocado, mind you. They’re not cheap after all.

Avocados are nutrient dense foods, so this is definitely a good choice for the king and not just a trendy one.

Tom Parker Bowles, the King’s stepson, revealed the royals’ eating habits in his new book, ‘Cooking and the Crown.’

The 49-year-old food critic and eldest child of Queen Camilla wrote: “Tea has always been a spectacle – and an important and substantial meal in itself – for the royals. Everyone congregates for tea.”

He added that his mother, Queen Camilla, ate a light lunch, while the King preferred afternoon tea over lunch.

“And it's not just cakes and biscuits and crumpets and sandwiches. You might even get poached eggs. If you are staying in Scotland, it's quite dangerous because you have a cooked breakfast, you have lunch, you have tea and you have dinner.”

Parker Bowles added that the King “appals waste.”

“There is no waste, everything is recycled, everything is used from the table.

“If anything is left over from the dinner, that will be made into something else or appear the next day. Nothing’s allowed to be thrown out.”
