In this episode, we invite Jennifer Little-Fleck to show us into the world of epigenetics. Find out what exactly epigenetics are, how they work, and how you can influence them for a healthy and happier you. You no longer have to be a slave to your genetics – tune in to find out how! 

Jennifer received her degree in Molecular Biology from the University of Pittsburgh and went into Transplant Research at the Thomas E. Starzl Transplant Institute soon thereafter. After performing many experiments on immune cell modulation and contributing to several scientific papers, she transitioned to working in the industry. Here, she was introduced to how research discoveries are taken to the public with the help of pharmaceutical companies. It was then when Jennifer realized that she had a passion for writing and teaching. Since then she has been involved in creating training materials for new drug therapies and working directly for drug companies for over 17 years. 

In 2016, Jennifer decided to expand her knowledge base and become a freelance medical writer. She now routinely writes launch training for therapies ranging from:

  • acne to Alzheimer’s
  • gene therapy for a variety of diseases
  • many types of cancer treatments
  • as well as medical devices such as breast implants, dermal skin substitutes, and diagnostic processes for measuring gene expression, to name just a few!

As Jennifer’s knowledge base began to increase, she was surprised by the amount of basic knowledge never taught to the general public that would help people to not only better understand the nature of potential conditions, but to also help avoid them.

Plus, she learned a lot of cool things about how amazing the human body is and thought it might be fun to share them in bite-size bits through a podcast called Autobiology Bits. Autobiology is the science of studying yourself as a living organism. It’s also a great way to show how everyone works a little differently from each other. No two people “work” exactly the same way when it comes to biology – not even TWINS! Jennifer’s aim is to explain those differences and why it matters to your everyday existence in the most fun and entertaining way possible.



  • What exactly is epigenetics and why is it such a game-changer?  
  • Misconceptions of epigenetics. 
  • The different influences on epigenetic changes. 
  • How your ancestry is linked to your epigenetics. 
  • Ways to support good methylation. 
  • Recommended formulations of Vitamin C. 
  • Signs of poor methylation. 
  • Magnesium: The role it plays in the body and the recommended intake. 
  • Is it too late to change your epigenetics? 
  • Methylation tests: How often should you take them? 



“We thought, way back in the 90s, that if we could understand all the genes in the body, that we would totally understand how to eradicate disease and fix everybody’s problems with. But what we learned was that it’s just a blueprint; it can be changed.” 

“You could be given good genes and put them to waste or you could be given bad genes and make the most out of it. And 85 to 90% of what you do determines what genes are switched on and what genes are switched off.”
