Michael Collins is a returning guest on our show! Be sure to check out his first appearance on episode 941 of Boundless Body Radio! 

Michael (Mike) Collins is the founder of http://sugaraddiction.com and a former sugar addict. For the past 30 years he has not consumed sugar in any form – at least not intentionally.

His interest in sugar addiction began in the early days of his recovery from substance use disorder. As he weaned himself off other substances, he noticed that his relationship to, and his consumption of sugar was beginning to resemble his other addictions. Curious and concerned, he started to talk about this with his recovery buddies.

This led him to decide to quit sugar with the help of some amazing mentors. Since then, he has helped hundreds of people personally and thousands online - quit, reduce or get under control runaway sugar use. With his wife, he raised two children sugar-free from the womb to six years old with zero sugar.

After many years of successfully starting, scaling and selling businesses, Michael decided that what really made him happy was helping people break their addictions of all kinds and come out the other side happier and healthier.

Dean and Jodie Schneitman are a married couple whose lives changed when Jody was diagnosed with Alzheimer’s disease in December 2023. Rather than accepting the diagnosis – no effective treatment and 100% terminal - they chose another path — researching the disease, consulting with physicians and scientists, and making major changes to nutrition, exercise, sleep, metabolic health, and daily lifestyle.

Dean, a retired teacher, has approached the journey with the curiosity of an educator and the determination of a husband who wants to leave no rock unturned. Jodie has met the challenge with remarkable discipline, participating in the routines and interventions they have built into their everyday life while continuing to remain active and engaged.

Their journey has included a carnivore-based diet, regular exercise, hyperbaric oxygen therapy, sauna, CPAP-supported sleep, and other lifestyle and metabolic approaches, along with ongoing medical evaluation and consultation with specialists. They are careful to distinguish between what is established, what is experimental, and what they have simply observed in their own experience.

Their story gained a much wider audience after they appeared in a long-form interview with Dr. Anthony Chaffee, Kelly Hogan, and Dave Mac where they spoke openly about Jody’s diagnosis and the path they have taken since.

Brendan Reesor is on a mission to transform perceptions of mental illness. Years ago, he made a significant change to his diet, which not only led to notable improvements in his physical health but also had unexpected effects on his mental well-being.

As he hoped, his once pallid complexion brightened, but he soon discovered that he was free from chronic anxiety and mild feelings of gender dysphoria that had previously troubled him. Intrigued by his own transformation, Brendan delved into research, observing that his past experiences were not isolated. He recognized a troubling pattern among others who, like him, shared traits of being plant-based, pale, anxious, gender dysphoric, and socially conscious.

Determined to uncover the deeper truths about mental health, Brendan explored the intricate relationship between physical health and emotional well-being. He began to decipher complex phenomena often overlooked by experts, including nightmares, sleep paralysis, panic attacks, hallucinations, dissociation, mass hysteria, and postpartum depression, all of which he connects to deficiencies in blood and oxygen.

In his book, Beyond The Pale: Anemia: The Visible Yet Unseen Cause of Mental Illness and Gender Dysphoria, Brendan invites readers to explore his findings and consider the often-unacknowledged role of physical health in understanding mental illness.

Trevor Folgering is the founder of The Metabolic Operating System (MOS), a metabolic health education and coaching system designed to help men over 40 improve their metabolism, energy, body composition, recovery, and long-term health.

With more than 25 years of experience in health, fitness, nutrition, and coaching, Trevor’s work challenges the traditional “eat less, exercise more” approach to weight loss. Instead, he teaches men to understand the metabolic signals their bodies are sending them - including hunger, energy, sleep, stress, cravings, and recovery, and use those signals to make better decisions about their health.

At the heart of Trevor’s philosophy is a simple idea: lasting change doesn’t come from fighting your body harder. It comes from understanding how your body is adapting and learning how to work with it.

Through The Metabolic Operating System, Trevor is working to change the conversation around metabolic health for men over 40 and help men build healthier, stronger bodies without relying on extreme diets or unsustainable approaches.
