Health Secretary Robert F. Kennedy Jr. launched a new dietary guidance website called RealFood.gov that links to Grok, Elon Musk's AI chatbot. The AI tool openly questions Kennedy's nutritional advice, calling him an unreliable source on health information. This comes after Kennedy released an upside-down food pyramid emphasizing fat and protein over traditional dietary guidelines.

Kennedy and Agriculture Secretary Brooke Rollins held a Washington, DC event to promote the guidance, featuring Mike Tyson and director Brett Ratner. The event highlighted a Super Bowl commercial starring Tyson, who made stigmatizing comments about obesity. The website design was credited to Joe Gebbia, Airbnb co-founder and DOGE member, who created the controversial funnel-shaped representation.

Nutrition experts have criticized Kennedy's guidance for glorifying fat and protein without sufficient evidence. When Grok analyzed a meal plan based on Kennedy's funnel, it found excessive saturated fat and protein while lacking recommended fiber. The chatbot acknowledged some alignment with whole food principles but noted the emphasis on protein and saturated fats goes beyond established research, reflecting political decisions rather than scientific consensus.
