Morgan Spurlock Says Trump's McDonald's Diet Fills a 'Sad Hole'

Morgan Spurlock thinks President Trump's obsession with McDonald's has psychological overtones ... proof he's an unhappy man looking for any form of fulfillment.

We got the "Super Size Me" star at LAX, and he weighed in on Trump's documented fast food campaign diet -- which at least once contained an estimated 2,500-plus calories full of junk food ... courtesy of good ol' Mickey D's.

According to Morgan, it's only a matter of time until Trump's heart explodes. Fifty four percent of Americans think that's impossible, because it presumes the existence of such an organ.
