Robert F. Kennedy Jr, also known as RFK Jr, recently revealed that he follows a carnivore diet, exclusively eating meat and fermented foods. He stated that he is very content with this diet and typically starts his day with a steak and sauerkraut, as confirmed by his wife, Cheryl Hines. However, his dietary choices have sparked debate online, with comedian Jason Selvig cautioning against taking medical advice from someone who follows such a diet.

RFK Jr's new US health guidelines, which heavily emphasize meat, dairy, and saturated fats, have faced criticism for potentially contributing to health issues and climate change. Some experts argue that increasing consumption of animal products could require millions of acres of additional agricultural land per year. In contrast, research suggests that plant-rich diets are better for health and the environment, and are essential for a stable food system.
