US President Donald Trump is expected to remain physically fit for the duration of his presidency and has "no cognitive issues whatsoever," according to full results from his first medical examination.
"All data indicates the president is healthy and will remain so for the duration of his presidency," doctor Ronny Jackson told a White House briefing following last week's physical, which determined the 71-year-old to be in "excellent" health.
"He has incredible genes and that's the way God made him."
Dr Jackson said the US President, who has recently faced a swirl of speculation about his mental fitness, had himself requested a cognitive test in which he performed "exceedingly well."
"I think he saw doing the physical as an opportunity to put some of that to rest," Dr Jackson said. "And I think he wasn't the least bit concerned that he had anything to hide."
The screening was carried out using a test called the Montreal Cognitive Assessment, on which Mr Trump scored 30/30, Dr Jackson said.
"He has absolutely no cognitive or mental issues whatsoever," Dr Jackson said, adding that it was to his knowledge the first time a serving US president had undergone such an assessment.
Dr Jackson gave the president's vital statistics as follows: height 6'3" (1.90 m), weight 108 kg, resting heart rate 68, blood pressure 122/74.
Heart rate, blood pressure and cardiac output were all normal in response to exercise, while motor function and sensory system were also normal, Dr Jackson said of Friday's exam at the Walter Reed National Military Medical Center.
"He has incredible cardiac fitness at this point in his life and I think a large part of that is due to the fact he has had a life of abstinence from tobacco and alcohol," Dr Jackson said.
Mr Trump's doctor however said that he would be working on a plan to try to cut calories, fats and carbohydrates out of the president's diet "as much as we can."

The press conference following Donald Trump's medical exam lasted for an hour. White House physician Dr Ronny Jackson fielded dozens of questions from journalists and said the president had told him to answer all queries put to him and to allow whatever time was needed. This was a chance for the White House to put to rest any rumours about the president's health.
Much of the focus in recent weeks has been on Donald Trump's mental capacity following the release of the controversial book "Fire and Fury", which questioned his fitness for office. Dr Jackson said the president had asked him to carry out a cognitive test to dispel these rumours. And how did he do? Well, to quote Dr Jackson, President Trump is "very sharp" and "very fit for duty".
The doctor was also asked about an incident a few weeks ago when the president slurred his words at the end of a speech. Dr Jackson said he could make no clinical findings in this area and perhaps it was due to a dry mouth brought on by medication the president had taken.
Overall, the president is in excellent health and is likely to remain healthy throughout his presidency. He doesn't drink or smoke but he does take some medication on a regular basis including a cholesterol drug, aspirin and a drug to prevent hair loss.
There's been a lot in the press recently about Donald Trump's eating habits, in particular his love of fast food and soft drinks. His doctor did concede that his patient would benefit from a lower fat diet.
He's also encouraged him to take more excercise and lose some weight. As the lengthy press conference drew to a close, one journalist asked how a man who doesn't excercise and eats high-fat food can be in excellent health. Dr Ronny Jackson replied that "it must be genetics."
Donald Trump has a lot of headaches these days. Not in the medical sense, as we've learned he has no concerns in that regard. No, his headaches are coming in the form of allegations of racism, investigations into possible Russian collusion and a stand-off with North Korea. The last thing the president needed was questions over his fitness for office.
A clean bill of health from the White House physician is just what the doctor ordered.
