A 30-second Super Bowl ad featuring boxing legend Mike Tyson and paid for by the nonprofit MAHA Center encourages viewers to avoid processed foods and visit Realfood.gov. The government website, which Health and Human Services secretary Robert F. Kennedy Jr. is promoting, provides resources on the administration’s new dietary guidelines, released in January, and encourages people to use Elon Musk’s AI chatbot Grok to “get real answers about real food.”
I decided to see how Grok’s advice aligns with the administration’s recommendations, particularly around protein intake. The new guidelines say to get 1.2 to 1.6 grams of protein per kilogram of body weight per day—more than what was previously advised—while the new inverted food pyramid prominently features steak and other animal products.
“We are ending the war on protein,” Realfood.gov states, echoing similar declarations by Kennedy.
Most Americans are already eating enough protein—and Grok agrees. In fact, so does the administration’s own “Scientific Foundation for the Dietary Guidelines for Americans,” which is linked on Realfood.gov. It says that US adults consume on average about one gram of protein per kilogram of body weight per day, or roughly 15 percent of total energy—the midpoint of the Acceptable Macronutrient Distribution Range, or ADMR—”suggesting that deficiency is rare.”
Following the website’s encouragement to ask AI for advice, I initially asked Grok how much protein I should eat based on my age, height, and weight. (Grok, it should be noted, frequently does not return answers to prompts, instead citing high demand and encouraging users to sign up for an account.) It recommended 0.8 grams per kilogram per day—the long-standing recommended daily allowance, or RDA, developed by the National Institute of Medicine. When I refined my question, saying that I do 30 minutes of strength training four days a week, Grok’s response was more in line with the administration’s new guidelines.
The recommendation of 0.8 grams of protein per kilogram per day is the minimum amount needed to prevent a protein deficiency for a sedentary lifestyle, which describes a significant portion of the American population. Nutritionists I spoke with agree that the new recommendations are more appropriate for people who exercise regularly.
“What I think the administration is trying to do is to target the metabolically unhealthy people who may need a little more protein to feel full and satisfied to build some muscle. But that nuance is lost with their single message,” says Lindsay Malone, a clinical dietician at Case Western Reserve University. “Then you go to this AI tool, and it’s almost too much information for the average person.”
While eating more protein can make you feel fuller so that you avoid snacking, she says, eating more protein on its own doesn’t build muscle, which is primarily built through resistance or strength training.
Michelle King Rimer, a clinical assistant professor of nutritional sciences at the University of Wisconsin-Milwaukee’s Zilber College of Public Health, says eating too much of any macronutrient—protein, fats, or carbohydrates—can lead to weight gain. “Consuming excess protein can still be converted into fat, which can lead to weight gain,” she says.
The administration’s messaging also says to “prioritize protein at every meal” with a mix of protein from animal and plant sources. Last week, Kennedy spoke about the “importance of meat protein” at the nation’s largest cattle trade show, declaring that “beef is back on the menu,” according to an HHS statement.
When I asked Grok which protein sources are healthiest, it listed plant-based proteins, fish and seafood, lean poultry, and eggs. The chatbot said to limit or minimize red meat and processed meats. That all reflects advice from major health organizations such as the American Heart Association and growing evidence that eating plant-based proteins and fish are associated with better health outcomes than diets high in red meat.
