Epigenetics, Brain Science and Finally Getting Free from Alcohol
Episode Overview
- Family history may raise the risk of alcohol use disorder, but lifestyle and environment can significantly influence how genes are expressed.
- Simple choices such as movement, sunlight, good nutrition and positive surroundings can reduce stress, support health and slow ageing.
- Practising the “daily 20” gratitude exercise helps retrain the reticular activating system to look for what is working, which weakens alcohol cravings.
- Relying on willpower, short-term challenges or casual accountability often fails; a structured, like-minded community makes lasting change more likely.
- Changing limiting beliefs about alcohol can shift feelings, thoughts, actions and, ultimately, life results for high achievers.
“You cannot change your genes, but you can change the expression of your genes.”
What can we learn from those who have battled addiction? In this science-led yet down-to-earth episode, James Swanwick shows how biology, mindset, and community can reshape a person’s relationship with alcohol.
Speaking directly to high performers in their 40s, 50s, and 60s, James tackles a common fear: “A lot of people are under the mistaken belief that if my father or grandfather had an alcohol use disorder, therefore I have an alcohol use disorder.” He explains epigenetics in simple terms: you can’t change your genetic code, but “you can change the expression of your genes” through lifestyle, stress reduction, movement, nutrition and environment.
You’ll hear about striking research, like twin studies from Cambridge showing how bullying altered health outcomes despite identical genes, and a Yale study where a simple plant at a hospital bedside shortened recovery time. These examples back up James’s message that everyday choices shape mood, health and resilience—key ingredients for an alcohol-free life. James also breaks down how alcohol hijacks dopamine and keeps people locked in a “pain, drink, numb, repeat” loop.
To counter this, he shares practical tools from his Project 90 community, such as the “daily 20” gratitude exercise designed to retrain the brain’s reticular activating system so it starts hunting for what’s going right instead of what’s going wrong.
The tone is direct, occasionally cheeky, and aimed at successful people who are “smart, intelligent, well-educated, successful in many areas of their life, except this one thing, alcohol.” If you’re tired of white-knuckling it, curious about the science behind cravings, and wondering whether a like-minded community might help, this episode offers plenty to think about and a nudge to ask yourself: are your beliefs keeping you stuck, or are they setting you free?
