The Unusual Diets of Tech Titans: A Look at Zuckerberg, Musk, and Buffett

Mark Zuckerberg, the CEO of Meta, has surprised many with his diverse interests, including his passion for Brazilian jujitsu. Since 2020, Zuckerberg has been practicing the martial art, and his dedication paid off when he won gold and silver medals at his first jujitsu competition in May this year. Despite the anticipation for a potential fight between Zuckerberg and Tesla CEO Elon Musk, the $117 billion man continues his grueling fitness regime, preparing for other bouts.
But it’s not just Zuckerberg’s martial arts training that has caught people’s attention. Recently, the tech mogul responded to a tweet from fast-food giant McDonald’s, who asked their followers about their favorite orders. In his trademark humorous style, Zuckerberg, known as “Zuck” on the app, responded with a list of items that included 20 nuggets, a quarter pounder, large fries, an Oreo McFlurry, apple pie, and even some side cheeseburgers for later.
While this may sound like an indulgent meal, with calorie estimates from McDonald’s website suggesting it exceeds 3,000 calories (more than double the recommended adult intake of 1,200 calories a day), Zuckerberg revealed that this unusually high-calorie intake is actually a tool for his training. In response to UFC fighter Mark Davis’ comment about being in camp and avoiding fast food, Zuckerberg retorted with a playful tone, saying, “Not cutting weight, so I need ~4000 calories a day to offset all the activity. And it’s so delicious…”
Zuckerberg’s love for fast food and high-calorie meals puts him in good company with other tech titans. Elon Musk, the owner of Twitter and Zuckerberg’s rival, has openly admitted to having a donut every day for breakfast. Meanwhile, Warren Buffett, the chairman of Berkshire Hathaway, is known for his unconventional diet, claiming to have the “diet of a 6-year-old”. Buffett famously includes Coca-Cola as a quarter of his daily calorie intake, consuming at least five 12-ounce servings daily.
Buffett’s love for Coca-Cola has become legendary, with reports of him serving glasses of the soda to Japanese trading houses and even starting his day with Oreos when visiting the home of Microsoft co-founder Bill Gates. Gates, who is a proponent of a plant-based diet, revealed that Buffett’s preferred meals consist mainly of hamburgers, ice cream, and Coke.

Despite his advocacy for a healthier lifestyle, Gates himself enjoys the occasional McDonald’s burger. According to Joe Cerrell, a managing director of the Gates Foundation, cheeseburgers are a staple during lunch meetings with Gates. Cerrell jokingly adds that if you have the lunchtime slot with Bill, you can expect someone to be sent to get bags of McDonald’s. However, it’s worth mentioning that Gates’ then-wife, Melinda, may not have been as lenient with the fast-food indulgence at home.
In summary, the unusual diets of tech titans provide an interesting glimpse into their personalities and lifestyles. From Zuckerberg’s high-calorie intake for training to Musk’s love for donuts and Buffett’s childlike diet, it’s clear that these billionaires have unique approaches to food. While their eating habits may not align with conventional health recommendations, their success serves as a testament to the idea that there’s no one-size-fits-all approach. So, whether it’s a cheat meal from McDonald’s or an indulgence in sugary treats, these tech moguls have found ways to make their diets work for them.
