WASHINGTON – President Donald Trump, a fast-food and red-meat connoisseur who eschews alcohol and tobacco, is in "very good health" his physician said Friday after a four-hour physical exam at Walter Reed National Military Medical Center in Maryland.

"I am happy to announce the president of the United States is in very good health and I anticipate he will remain so for the duration of his presidency, and beyond," Dr. Sean Conley, the president’s physician, wrote in a memo released by the White House.

Trump’s health has long been a subject of interest, despite a doctor’s assessment last year that he has “incredibly good genes” and was in "excellent health." The 72-year-old president doesn’t exercise regularly, beyond golf, and acknowledged last year he takes a statin drug designed to lower his cholesterol.

The president spent four hours at Walter Reed. He returned to the White House Friday evening and did not respond to shouted questions from reporters.

The president, ringing in at 6-foot, 3-inches, had a body mass index last year of 29.9, which places him in the overweight category on the verge of obesity, which is defined as a BMI of 30 or greater. Similar details from this year were not yet available.

Dr. Ronny Jackson, who performed the assessment last year, reported that – like many Americans – the 239-pound president could use more exercise and a better diet that is lower in fat and carbohydrates. After anonymous sources questioned the president’s mental capacity in the bombshell book "Fire and Fury," Jackson last year performed an assessment to screen for cognitive impairment.

Trump got a perfect score, Jackson said.

"The president is mentally very sharp," the doctor said at the time.

Jackson withdrew himself from consideration to lead the Department of Veterans Affairs last year amid a barrage of allegations of prior misconduct. This year, Trump’s exam was performed by Conley, a Navy veteran. Conley said he performed and supervised the assessment along with a panel of 11 board certified specialists.

Jackson provided a brief summary on the day of the president's exam last year. He then briefed reporters with test results and a more detailed analysis the following week.

Other results from Trump's physical last year:

• Trump had a total cholesterol of 223, slightly over normal, and a blood pressure reading of 122 over 74, which is within the normal range.

• The president had a resting heart rate of 68 beats per minute. Sixty to 100 beats per minute is considered normal.

• Trump has a history of elevated cholesterol and was taking a low dose of Crestor to treat it. He also takes aspirin, 81 milligrams daily, for cardiac health.
