Experts rip into the ‘Lion Diet’ where people only eat meat and salt for 30 days

A controversial diet promoted by Jordan Peterson has sparked concerns with health experts, with the 'Lion Diet' raising some serious red flags.

The health kick spruiks itself as a 'healing elimination diet', but medical professionals reckon it is 'high in saturated fat'.

They also described itself as 'unsustainable and likely to lead to nutritional deficiencies'.

Cool, cool, cool.

"Couple this with non-existent fibre intake, and the risk increases further, not to mention other health issues which are highly likely, such as constipation, high blood pressure and if followed for some time, osteoporosis," she said.

She added: "There is no valid reason [to adopt the diet]. It is so disappointing to see this meat-only diet be given a platform, particularly when aiming to appeal to those with debilitating health conditions such as rheumatoid arthritis, and claiming it helps improve mental health issues."

The biggest names giving the diet a platform both come from the same family: Controversial Canadian author and clinical psychologist Jordan Peterson and his daughter Mikhaila.

Peterson said: "I’m certainly intellectually at my best. I’m stronger, I can swim better, and my gum disease is gone. It’s like, what the hell?"

Mikhaila also claims she helped create the Lion Diet, describing it as a

'cure-all' which helped her beat a number of health problems she had struggled with since childhood.

"My brain and gut were so damaged that an all-beef or ruminant meat (like lamb and bison) diet, what I call the Lion Diet, was all I could tolerate," the podcaster said on her website.

The 28-year-old has been on the diet for five years now and claims she is 'healthy' and wants to share the diet with others so people 'can improve their life themselves'.

With those meals, the Health Foundation also calls for meat to be eaten with vegetables and whole grains.
