In this episode, we dive into the fascinating and controversial world of epigenetics, exploring whether exercise, nutrition, stress, sleep, obesity, and overall lifestyle can leave biological signals that may influence future generations. Before anyone panics, no we're not suggesting your sperm has ears. But emerging research suggests that the environment you create within your body may alter how genes are expressed, potentially affecting offspring through mechanisms such as DNA methylation, RNA signalling, mitochondrial function, and metabolic regulation. We break down: What epigenetics actually is (without the PhD lecture) The difference between genetics and gene expression How exercise may influence biological signals passed to offspring Why paternal health before conception may matter more than people realise The role of sperm RNA, DNA methylation, and mitochondrial health Whether obesity, inactivity, poor sleep, and chronic stress can create downstream consequences The fascinating studies looking at exercise and offspring metabolism Why this area of science is both exciting and heavily misunderstood The dangers of biohacking gurus overselling preliminary research What this really means for parents, future parents, coaches, and everyday people Along the way, we discuss responsibility, legacy, modern lifestyle, and whether health is about more than just looking good in the mirror. This isn't an episode about creating super babies or chasing the latest optimisation trend. It's a conversation about how the life you live today may be shaping far more than you think. Because maybe the most important question isn't: "What genes did I inherit?" It's: "What signals am I teaching my biology every single day?" 🧬💪🏻 Tune in for one of the most thought-provoking conversations we've had on the podcast.
