The physician, who was appointed to the White House post by President Barack Obama and retained by Trump, said that Trump's diet had changed since he took office. His cholesterol treatment will be increased, the White House doctor said.
Dr. Elizabeth Roth, an internist at Massachusetts General Hospital who also has not examined the president, said heart health is among the biggest concerns for any man his age - Trump is 71 - and that several factors contribute to whether he is in imminent danger, including weight and cholesterol.
"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", Jackson said. "It would pick up on it", Dr. Jackson said. "I think he will remain fit for duty for the remainder of this term and even for the remainder of another (four-year) term if he's elected". A NY driver's license issued in 2012 listed him as 6 feet 2 inches tall, which would put him just into the obese category.
According to the New York Times, the survey showed Trump's approval among black Americans "actually declined from 20 percent in February 2017, his first full month in office, to 15 percent in December".
Trump achieved 30 out of 30 on the Montreal Cognitive Assessment, a 10-minute test ranging from identifying illustrations of animals to naming in one minute as many words as possible that begin with the letter F. "Anybody who knows my father could tell you that he has more energy than any human being".
Jackson says he will come up with a programme of exercises for trump, which doesn't put your joints at risk.
"He has incredibly good genes and that's just the way God made him".
Donald Trump has aced a test on his mental health - likely putting to rest days of Washington political gossip. "It took significantly longer to complete, and the president did extremely well on it", Jackson said.
Developed in Montreal in 1996, it was created to measure "mild cognitive dysfunction" according to the Canadian Partnership for Stroke Recovery.
Here's a look at what we found out about the president's health from Jackson.
"We talked about diet and exercise a lot, he's more enthusiastic about the diet part than the exercise part, but we will do both", Jackson said.
Trump is the first US president to undergo cognitive ability tests.
