Well how much energy are you claiming he has, more or less than the average person?
trump campaigned like a rich man with a hobby. He flew home every night during the campaign to sleep in his own bed. He wasn't sitting in a bus criss-crossing the country, with all the rigors that entailed. So Hillary had him beat in that sense.
NEW YORK (Reuters) - U.S. presidential candidates are spending long days on the campaign trail and their nights in a succession of budget hotels, often in small towns. Not Donald Trump.
After nearly every rally, the billionaire real estate developer hops into one of his planes or helicopters and returns to New York so that he can sleep in his own bed in his marble-and-gold-furnished Trump Tower apartment in Manhattan.
In November and December, Trump held six rallies in Iowa, visited a local production plant and held one town hall, flying home each night. His nearest rival for the Republican nomination, Ted Cruz, has zigzagged around the state, holding around a dozen town halls and twice as many "meet-and-greet" sessions, and bedding down between stops in hotels.
Trump’s determination to sleep at home every night raises eyebrows among election campaign veterans, who say it could cost him. Voters in Iowa and New Hampshire often want more personal attention; they feel they play a special role in choosing presidential nominees because their contests are held first.

I believe it was Blow Job Bill that was the last president that had a fat problem......all it took was open heart surgery and bottle after bottle of speed to cure the problem.
