Mikhaila Peterson only eats beef.

No vegetables, no fruit, no grains, no nothing - and yes, she knows it’s strange, describing it to me as “ridiculous sounding”.

But the 26-year-old mum of one, and daughter of famous psychologist Jordan Peterson, sees the the all-beef way of eating as a necessity after crediting it with the elimination of her severe arthritis, depression, chronic fatigue and skin problems.

To most healthy people, the idea of such a restrictive diet sounds miserable, but when you listen to Mikhaila outlining her medical history of autoimmune issues, you quickly realise she’s suffered worse.

In #HealthHackers episode 17, Mikhaila told me she was diagnosed with severe rheumatoid arthritis aged seven and had to have hip and ankle replacements at the age of 17.

She was diagnosed with depression in the fifth grade (that’s the last year of junior school for you UK readers), and also later developed fatigue, skin rashes and cystic acne into her early twenties.

“The arthritis was bad, the depression was bad, but as soon as it got to my skin I was like, ‘Oh now whatever’s wrong with me is visible and that’s just so much worse.’ ”

Mikhaila decided to experiment with diet; cutting out various foods and reintroducing them to see the effects on her symptoms, eventually concluding she was having bad reactions to most of what she was eating.
