Trump’s diet, however, is more reflective of the way the general American public eats. He has proudly articulated a love of fast food, especially McDonald’s, KFC, and Wendy’s, because he proclaims that these foods are guaranteed to be safe from any contaminants. (He has been conspicuously silent about Chipotle.) Trump also has a strange obsession with calories and carbs. He’s been known to scrape off and eat the cheese and other toppings from his pizza and ignore the dough (how very un-New York of him), and he drinks a lot of Diet Coke. A letter from his personal physician shows that Trump is on the border of being overweight and obese, but, despite this, his physician said “he would be the healthiest person ever elected president.”
