Dieticians have their say on whether RJK Jr’s popular Sauerkraut diet can help you lose weight

  • A diet craze involving fermented foods like sauerkraut and kimchi has reportedly gained traction among senior US administration figures, including Health Secretary Robert F. Kennedy, Jr., Vice President JD Vance, and others.
  • Kennedy claims to have lost significant weight and alleviated other health issues by adopting this diet, often combined with a carnivore approach, and suggests many colleagues are following suit.
  • Registered dietitians confirm that fermented foods offer health benefits, particularly for gut health due to probiotics, which can positively impact metabolism, brain, heart, and immune systems.
  • However, experts caution that these foods are not a standalone weight loss method and can be high in sodium, potentially posing risks for people with conditions such as hypertension.
