Brigitte Macron insists on eating ten fruit and vegetables every day to keep svelte while her husband Emmanuel is partial to a more fattening cordon bleu, the head chef at the Elysée Palace has revealed, reports The Telegraph.
In an interview with the Telegraph, Guillaume Gomez, 39, who has served meals for four successive presidents, said the menu was always "adapted" to presidential tastes, but centered on French cuisine.
"Let's not hide behind false modesty," he said. "Some 70 per cent of tourists who come to France say they do so for its gastronomy."
He added: "We serve only French products at the president's table if possible. Naturally the coffee isn't French, but all our fish, meat and fruit and vegetables either come from mainland France or from overseas territories.
"We prioritise local food produced less than 100 km from Paris for fruit and vegetables and some dairy products."
Around half of the Elysée ingredients are organic, while some of the herbs, including rosemary and laurier are grown in the palace's vast gardens.
There is a plan next spring to open an organic presidential vegetable patch - either at the Elysée or Versailles Palace.
And while Mr Macron is busy modernising France upstairs, Mr Gomez is urging his countrymen to get back to basics in the kitchen.
He has just published a recipe book - Cuisine, Step By Step Lessons - focusing on the techniques underpinning classic French dishes from boeuf bourguignon to pot-au-feu and quiche Lorraine.
"If you want very modern recipes or fusion, this book isn't for you," said the bear-like chef, sitting in his office with a large photo of Mr Macron handing on the wall and a framed certificate of the Meilleur Ouvrier de France (Best Worker in France) award granted to only a handful of the country's top chefs.
