The King’s former press secretary Julian Payne, shared King Charles’s former day-to-day life when he was heir and described it as “pretty relentless”. According to Mr Payne, the King “doesn’t eat lunch” and often eats the same meals every day.
The former press secretary said: “An early lesson I learnt when out on the road with him was to have a big breakfast or bring a few snack bars with you to keep you going.
“The working day is pretty relentless. Beginning with the radio news headlines and a breakfast of seasonal fruit salad and seeds with tea.”
The King does take some time away from work at 1pm every day, however, it is “not to eat but to get outside to walk”.
Mr Payne added: “The King dislikes being inside for too long and always has the windows wide open.”
The King would spend a day in his office spending around 45 minutes on each of his charity’s new projects, planning an upcoming royal tour or in discussion with his principal private secretary, Sir Clive Alderton about matters of state.
King Charles’s first proper break of the day would be around 5pm when he would have some tea, sandwiches and fruit cake with the Queen Consort Camillia.
He would then spend his evening at his desk doing paperwork, and would often be working well past midnight.

Mr Payne says the only evening break King Charles would take would be at 8:30pm precisely when dinner would be served.
The King’s schedule is planned six months in advance twice a year and goes into an organised diary.
When he’s not home, the schedule is a mixture of invitations for his four hundred charities which he is a patron of, military events, and royal duties which include work such as opening parliament and Remembrance Sunday.
Mr Payne adds that the King’s busy life is also true of public engagements, as he often spends hours talking to people and is always happy to chat.
A famous example of this was at a James Bond premiere years ago, in which King Charles accidentally kept actor Daniel Craig waiting because he spent a good deal of time speaking with set designers and security guards.
