Princess Anne carried out no fewer than 214 engagements last year despite the bereavement of losing the late Queen.
This week it was announced that the Princess Royal has been given a leading role in the Coronation - where the King's sister will act as "personal aide-de-camp" riding behind Charles and Camilla on horseback following the ceremony.
Her busy role shows no signs of abating - but what does Princess Anne eat to fuel so many public appearances? The royal is said to skip lunches, just like the King, meaning a filling breakfast is vital to get through long days of visiting places and meeting people around the country.
