The old adage that you should eat breakfast like a king, lunch like a prince, and dinner like a pauper may be going the way of the dodo. At least that's what Dr. Mehmet Oz believes. He'd like to abolish breakfast altogether to give our metabolism a boost.

"I think for 2020, the first thing I am going to do is ban breakfast," he recently told TMZ. "I don't think we need to eat breakfast. That's an advertising ploy.

"Unfortunately, a lot of the dogma we were fed for decades came out of advertisements, it wasn't based on the truth about our health.

"The smartest thing for us to do is cancel breakfast, have your first meal when you're actually hungry."

Oz believes in intermittent fasting and suggests that if you eat a proper dinner, you shouldn't be starving first thing in the morning. So, what's going to happen to the all-American tradition of bacon, eggs, and pancakes? The famous doctor advises us to eat only when we are truly hungry, which would be mid-morning. "You should have brunch every day of the week," he advises.

Oz's theory has its fair share of critics, most notably actor Mark Wahlberg, who wakes up at 2:30 a.m. and eats breakfast at 3:15 a.m. before he does his famous F45 Training Workout.

"Listen, I don't care what Dr. Oz says, I gotta have my breakfast before I work out," the 48-year-old Wahlberg and his six-pack abs says. "That's my preference."

Oz challenged Wahlberg in a Twitter video.

"Mark, I heard you said that I was dead wrong when it comes to canceling breakfast," he said. "Well, powerful medical literature and lots of athletes support me and show that intermittent fasting flips the metabolic switch so it bolsters your physical and mental performance."

However, dietitian Kristin Kirkpatrick, the manager of wellness nutrition services at the Cleveland Clinic Wellness Institute, told the Today show that "not only should you NOT skip breakfast, you should make it the biggest meal of the day."

She cited a 2017 study published in the Journal of the American College of Cardiology that followed female volunteers. The study found that those who skipped breakfast had a higher degree of hardening of the arteries. Another study found that individuals who made breakfast the largest meal of the day were more likely to lose weight than those who made lunch or dinner their largest meals. A study of type 2 diabetics patients found that a large breakfast containing protein helped in the management of their disease.

And Heather Gunn Rivera, co-founder of the Grassroots Fitness Project, tells Newsmax that breakfast should be a personal preference.

"While I believe that eating breakfast is not for everyone and that when we finish dinner determines when we should break our fast, I don't believe that not eating breakfast should be a blanket statement," she says. "Breakfast means 'breaking your fast,' so it just becomes a different time of day depending on the individual.

"If the point Dr. Oz is making is to get people to listen to their bodies and eat only when they are hungry, then that should be the focus. Otherwise, you will have people waiting for lunch even when they are hungry because the message is 'quit breakfast.'"
