Bear Grylls regrets promoting veganism in the past.

Bear Grylls, a former vegan and now a meat-lover, said he's "embarrassed" about his past promotion of plant-based diets. Grylls claimed that eating meat and organs has been a "game-changer" for his health, without citing evidence. He now advocates for the "ancestral way of living" and prefers to adopt a carnivore diet. However, studies have shown that a wider societal shift toward plant-based diets could have a great positive impact on the environment and reduce the risk of cardiovascular diseases.
