You may have heard that your genes are your blueprint, but what if that blueprint could change its expression based on how you live?
In reality, your DNA isn’t your destiny. It’s a dynamic system, constantly influenced by the choices you make and the environment you live in. The way your genes are expressed, meaning which ones are turned on or off, can be shaped by what you eat, how you sleep, how you move, how you handle stress, and even when you do these things. This is the field of epigenetics, and it’s opening the door to a whole new way of understanding health.
In this blog, we explore how your daily habits and surroundings impact gene expression through various scientific lenses:
Nutrigenetics: how your genetic makeup affects your response to nutrients
Nutrigenomics: how nutrients and diet influence the way your genes behave
Epigenetics: how lifestyle and environmental inputs switch genes on or off
Chronobiology: how timing, like sleep patterns and meal timing affects biological rhythms and gene activity
Environmental medicine: how toxins, pollutants, and even light exposure impact gene regulation
Lifestyle medicine: how exercise, stress management, and social connection influence long-term gene expression
Understanding how these factors interact with your genes gives you more than insight — it gives you agency. Because if your environment can switch genes on or off, then so can you. Let’s explore how you can start influencing your biology, instead of being shaped by it unconsciously.
We often hear people describe themselves as "naturally skinny," "stocky but strong," or "built for speed." These descriptions tie back to the concept of body types, or somatotypes — a classification system that outlines three general body compositions: ectomorph, mesomorph, and endomorph. But where do these traits come from? And how does your DNA influence the way your body stores fat, builds muscle, or burns energy?
For decades, scientists have explored how our environment shapes our biology. But one of the most fascinating — and often overlooked — aspects of that environment is our inner world: our thoughts, feelings, and emotions. Today, a growing field of research shows that our emotional states don’t just affect our mood or mental health — they can reach deep into our cells and influence how our genes behave.
Have you ever wondered how a tiny bit of saliva or a cheek swab can tell you so much about your ancestry, health, or even which vitamins you need more of? The secret lies in a process that works like a photocopier for your DNA.
After exploring the full journey of thyroid hormones — from brain signaling to production, conversion, immune impact, and detoxification — one thing is clear:
We’ve followed thyroid hormones from the brain’s initial signal to production in the gland, transport through the blood, and activation in the tissues. But even active hormones don’t stick around forever. Eventually, they need to be cleared — safely broken down and excreted from the body.
The thyroid is one of the most common sites in the body for autoimmune disease. In fact, autoimmune thyroid disorders (AITDs) affect millions worldwide — with Hashimoto’s thyroiditis and Graves’ disease being the most well-known forms.
