Health and Human Services Secretary Robert F. Kennedy Jr., Commerce Secretary Howard Lutnick, Transportation Secretary Sean Duffy and Vice President Vance have adopted a diet centered on fermented foods and grass-fed meat, according to a Wall Street Journal report.

The diet is recommended by Dr. Sean O Mara, who encourages patients to eat more sauerkraut, kimchi and grass-fed steak while cutting out alcohol and sugar. He says the approach reduces visceral fat and supports gut health.

Kennedy was the first to adopt the diet about a year ago, followed by Lutnick and Duffy. Vance began the diet during Lent this year and has continued it, according to the report.
