Mikhaila Fuller (formerly Peterson) is a founder, CEO, podcaster, lifestyle and diet researcher, wife, mother of two, and speaker.

From age 2, she battled severe juvenile idiopathic arthritis, idiopathic hypersomnia, and depression, leading to hip and ankle replacements by 17. She put herself in remission at 23, in 2015, by adopting a strict paleo-style diet she came up with, eliminating eight medications. This process included two years of intense antidepressant withdrawal.

In 2017, she developed the Lion Diet—a plant-free, ruminant-meat-based, ketogenic elimination diet—to address lingering health issues and withdrawal. The diet has helped tens of thousands manage autoimmune and psychiatric disorders, obesity, and food sensitivities. Information, including guides and resources, is available at liondiet.com.

Since 2018, she has managed her father Jordan B. Peterson’s brand, overseeing PR, strategy, and social media. In 2020, she launched the Mikhaila Peterson Podcast, covering health, relationships, and psychology. Her series “Opposing Views” features experts debating contentious topics to encourage critical thinking.

In 2022, she founded Fuller Health, offering pure, non-toxic supplements, starting with After Party, a product to alleviate hangover symptoms. In 2023, she created biotoxin.com to help people navigate illnesses caused by environmental toxins like mold.

Currently, she is co-founder and CEO of Peterson Academy, an online education platform launched in 2024, offering affordable courses from top professors and fostering community connections.

Mikhaila’s goal is to encourage people to become resilient, and to recognize how much control they have over their own life. To encourage others to take responsibility for their physical and mental health, and to help show people that they have the power to improve their lives, regardless of the cards they’ve been dealt. She also plans to fund research into plant-free ketogenic diets from her businesses to delve deeper into treatments for chronic disease. 

You never know what level you can reach if you decide to put in the work.
