Genetics influence our health, but they don’t determine the whole story. Things like heart disease or diabetes often run in families, but the way those genes actually show up in your life depends heavily on your daily environment. That’s where lifestyle comes in.
Nutrition, strength training, regular movement, lower stress, better sleep, and even social support can change how genes are expressed. This field is called epigenetics: basically how behaviour and environment influence biology.
You can’t change the genes you were born with, but you can influence how those genes behave. Someone with a family history of metabolic disease who lifts, eats well, and sleeps consistently will usually have a different outcome than someone with the same genes who doesn’t. It’s not about eliminating risk, but about reducing it and improving healthspan.
It’s more empowering to view genetics as a starting point, not a guarantee.
