US President Donald Trump has given up fast food and is now eating more fish, salads and soups in a bid to avoid obesity, Bloomberg has cited sources familiar with the situation as saying.

Twitter users minced no words discussing Bloomberg's report about US President Donald Trump's doctor advising him to stick to a diet and replace hamburgers with salads in his menu.

Some users jokingly expressed concern about Trump adding to a global trade war because of his diet, while others remained skeptical about his commitment to his doctor's advice.

At 239 pounds (108 kilograms), the 6'3" (192 centimeter) tall Trump is currently only one pound (400 grams) shy of being obese, according to the guidelines of the US Centers for Disease Control and Prevention (CDC).

A source told Bloomberg that Trump had not eaten fast food for two weeks now, a sea change from his traditional menu, which typically included two McDonald's Big Macs, two Filet-o-Fish sandwiches and a chocolate milkshake.
