Prince Charles, 72, is purportedly a stickler when it comes to a certain eating habit, insiders have revealed. According to sources close to the Prince, Charles rarely has lunch as he follows a diet similar to an intermittent fasting diet.

       The Prince of Wales reportedly eats a light breakfast which is then followed by one main meal at dinner.

       Charles is also said to eat the same breakfast every single day.

       According to royal author Sally Bedell Smith, the Duke of Cornwall eats specially mixed wheat germ and cereal grains with honey.

       This is usually followed by fruit and tea.

       But on weekends Charles opts to eat Clarence House's own cheesy baked eggs recipe.

       The 72-year-old's diet also sees the Prince of Wales skip lunch altogether.

       And the decision to miss the midday meal has caused some issues for Firm insiders.

       A Clarence House source told the Daily Mail: "It can be a problem sometimes.

       "When we do day visits or foreign tours, he can go the whole day without stopping for a break, which means we all have to miss our lunch as well."

       The source added: "It's good in a way, because it means he has time to meet more people, but he doesn't seem to notice all the rumbling stomachs around him.

       "You just learn that you have to have a big breakfast on those days."

       However, an ex-royal correspondent has revealed how many insiders close to the Prince of Wales have got around Charles' difficult dietary habits.

       The journalist also confirmed the Duke's tendency to skip lunch.

       Gordon Rayner told The Telegraph: "Lunch is seen as a luxury that gets in the way of his work, so he eats a late breakfast and works through.

       "I found this out the hard way, by going hungry when I started covering royal tours and watching enviously as his long-suffering staff produced snacks from pockets so they could eat on the go."
