Bear Grylls Adopts Carnivore Diet and Focuses on Health Span at 52
Bear Grylls, the 52-year-old British survivalist and former SAS reservist, has shifted his focus to optimizing his health span, according to welt.de. Best known for hosting survival shows where he drank his own urine and consumed raw animal parts, Grylls now wakes up at his London penthouse overlooking Battersea Power Station to lift heavy weights and prioritize a meat-heavy diet. His daily routine combines cold-water exposure, natural foods, and intense training sessions.
From Survival Television to Modern Longevity Pursuits
Grylls gained fame in 2006 with his television series Born Survivor, known in Germany as Ausgesetzt in der Wildnis on DMAX, where high-profile guests including Kate Winslet and Barack Obama joined him to leave their comfort zones. welt.de reports that the adventurer has now turned his attention toward the fast-growing longevity movement, a space dominated by biohackers and Silicon Valley billionaires aiming to extend their functional lifespans. While initially skeptical of the trend, Grylls notes that pioneers are often viewed as eccentric before their ideas gain mainstream acceptance.
Transitioning to a Carnivore Diet and Organ Meats
Dietary choices form the cornerstone of Grylls’s current health philosophy. After following a vegan diet for roughly five years, he shifted to a carnivore diet in 2020. welt.de reports that this transition was triggered by health issues experienced by his oldest son, Jesse, who suffered from stomach problems and fatigue on plant-based foods. Grylls states that his own persistent kidney pains vanished after he stopped drinking daily raw juices and reintroduced meat. He now consumes large amounts of steaks, eggs, and nutrient-dense organ meats such as liver, which he compares to the natural diets of apex predators like lions and orcas.

Grylls Launches Modern Savage Supplement Business with Family
To commercialize his nutritional philosophy, Grylls partnered with his wife, Shara, and their oldest son, Jesse, to launch a family business called Modern Savage, as reported by welt.de. The enterprise produces nutritional supplements derived from dried bison organs and beef proteins. Their younger sons, Marmaduke and Huckleberry, assisted with product testing. Grylls emphasizes that building businesses with his family takes precedence over financial success, noting that true wealth is measured by the quality of personal relationships rather than monetary accumulation.
