Less than a month into Donald Trump’s term in office, there are already countless distinctions between the Trump administration and the Obama administration. Americans are passionately debating the implications of the policy distinctions Trump is drawing on a daily basis.

However, Axios recently focused on a slightly less critical, although certainly potentially important, difference between Trump and Obama.

President Obama and his wife Michelle made fitness, diet and health priorities while in office, but Trump’s diet seems more appropriate for a college dorm room than the White House. His eating habits even provided some excellent free product placement for top brands from time to time.

Aides report that Trump was constantly guzzling The Coca-Cola Co (NYSE: KO)'s Diet Coke on the campaign trail.

One aide referred to Domino’s Pizza, Inc. (NYSE: DPZ), McDonald’s Corporation (NYSE: MCD) and Yum! Brands, Inc. (NYSE: YUM)'s KFC as the three staples of the Trump campaign trail diet. Trump apparently has a special place in his heart (and his stomach) for the Big Mac.

While some Trump critics rolled their eyes at pictures of Trump eating Big Macs and fries on his private jet, aides say these occasions weren't simply photo ops to make Trump seem more relatable to voters; He frequently had Big Macs served to him on a silver platter, according to the Axios report.

In addition to fast food, Trump frequently snacks on PepsiCo, Inc. (NYSE: PEP)'s Lays potato chips and Kellogg Company (NYSE: K)'s Keebler Vienna Fingers.

Why should this unhealthy lifestyle concern Americans? At age 70, Trump is the oldest president ever elected. In addition to his poor eating habits, aides also report that Trump doesn’t exercise, other than playing an occasional round of golf.

Trump hasn’t had any major health issues up to this point, and aides report his diet has improved somewhat since the campaign ended. Trump also enjoys steaks (well done), potatoes, fish, seafood and vegetables. He doesn’t smoke and doesn’t drink alcohol at all.

For better or worse, Trump is certainly following through with his campaign promises when it comes to policy. As noted by Axios, aides report he's also a man of his word when it comes to Oreo cookies as well. Trump apparently used to love snacking on Oreos, but he gave them up entirely after Mondelez International Inc (NASDAQ: MDLZ) moved an Oreo plant from the U.S. to Mexico.

Update (Dec. 21): In a new book, former Trump campaign manager Corey Lewandowski and former deputy campaign manager David Bossie dish on working for Trump. As CBN notes:

"One of Lewandowski's many duties was to make sure Trump's meals on Trump Force One were hot and on time. In the book, he jokes there were four main food groups for the ever-busy candidate and campaign: McDonald's, Kentucky Fried Chicken, pizza and Diet Coke."
