Former President Bill Clinton looked remarkably trim as he left a plush London restaurant on Thursday night.

Bill Clinton, 66, had been enjoying a dinner with actor Kevin Spacey at the upmarket Scott’s seafood restaurant in Mayfair, after giving a speech in London.

The former president, formerly known for his love of burgers, barbecue and junk food, changed to a strict vegan diet in 2010 after fears over his health.

Bill Clinton had quadruple bypass surgery in 2004 and then stent surgery in 2010.

He now follows a strict eating plan to improve his heart health.

Bill Clinton says he eats fruits, vegetables and beans, but no red meat, chicken or dairy.

His weight-loss was much commented-upon before his daughter Chelsea’s wedding, after which he said he had lost at least 24 pounds.
