Bear Grylls has claimed to eat a diet heavy in meat and raw dairy, as well as organs including pancreas, liver, and heart.
The British adventurer, 48, posted a video to Twitter detailing the foods he eats to âstay strong.â As well as consuming what he calls âgood quality grass-fed meat,â he said he also âthrows in a bit of liver every few days.â
Grylls claimed to take what he calls âancestral supplementsâ containing organs like pancreas, heart, and testicles. He urged his followers to âcheck them out,â and added that âthe truth is we need more organs than just liver.â
He said he doesnât eat much bread or pasta, and claimed to stay away from processed foods that are full of âdamaging seed oils.â
The video sparked backlash from followers, with some questioning the plausibility of his advice. âWhy should I change my way to eat?,â one wrote. âHappy you found out whatâs good for you, but take care of your health! Carnivore diet contains risks, tooâŠâ
Another said: âThe truth is we donât need to eat more organs, absolute nonsense.â They added that the video was âdisappointing.â
Bear Gryllsâ questionable claims
Grylls captioned the video with the words: âââIâm often asked my secret to having the energy to tackle some of lifeâs toughest challenges? Nutrition is key, as is resistance training, sunlight, cold water, and fun community.â
Some of the claims he made in the video are scientifically dubious, however.
He said there was âso much researchâ on how much we âneedâ red meat. This is despite the fact that a great deal of research has found that plant-based and meat-free diets are acceptable, as well as optimal, for human health.
Bear Grylls moves away from veganism

It may come as a surprise to some that Grylls claims that he used to eat a mostly plant-based diet.
In an interview with Louis Theroux in November 2022, he said that his âhealth tankedâ while eating vegan foods and that he âcertainly couldnât do 25 pull-ups.â
He also claimed that he now eats steak âtwice a day,â and appeared to justify his diet on the grounds that vegetables like broccoli âcouldnât defend themselvesâ in nature.
