Jackson said that he has a goal for the president of losing 10-15 pounds through a regimen of diet and exercise, telling reporters, "He's more enthusiastic about the diet part than the exercise part, but we're going to do both."



In general, though, Jackson was upbeat about Trump's physical condition, prompting questions about how a septuagenarian man with such seemingly poor habits, including little apparent exercise apart from golfing (while driving in carts) and an affinity for greasy fast food, could fare so well in a thorough examination. "It's called genetics," the physician replied with a shrug.



"The answer to your question is that he has incredibly good genes," added Jackson, "and it's just the way God made him."



Nevertheless, some took issue not just with the president's listed weight, but his height, as well. Photos were posted comparing Trump, at a purported 6-3, to his predecessor, Barack Obama, who was listed at 6-1.



Jackson, who has been the lead White House doctor since 2013 and oversaw two of Obama's physicals, told media members Tuesday that 12 other doctors consulted on Trump's examination, which lasted more than three hours. Before he spoke, White House press secretary Sarah Huckabee Sanders read a letter from former longtime White House physician Richard J. Tubb, who trained Jackson and vouched for his integrity.
