Are you ageing faster than you think?
If someone asked your age, you’d probably answer without hesitation. But here’s the twist: that number — your chronological age — might not match how old your body actually is.
Welcome to the world of biological ageing — where how you live matters more than when you were born.
What Is Biological Age?
Biological age refers to the condition of your body and cells, not the number of birthdays you've had. It reflects how well your systems are functioning, how quickly your cells are renewing, and how much wear and tear you’ve accumulated. over the course of your life.
Think of it like this:
Two people could both be 45 years old on paper. One might be thriving with great sleep, regular movement, and a nutrient-dense diet — and biologically be closer to 38. The other may have years of poor sleep, stress, and processed food behind them — and be biologically 52.
The difference can have a huge impact on health span, energy, and disease risk.
What Speeds Up Biological Ageing?
Several factors can age your body faster than your actual years:
Chronic stress (hello, cortisol overload)
Inflammatory foods and nutrient deficiencies
Lack of sleep or poor sleep quality
Exposure to environmental toxins
Sedentary lifestyle
Smoking or excessive alcohol use
These stressors can accelerate cell damage, shorten telomeres (protective caps on your DNA), and reduce your body’s ability to repair itself — pushing your biological age higher.

So, can you reverse it?
The good news? Biological age isn’t fixed.
Small, consistent changes in how you live can have a powerful impact.
Research shows that supporting your body through:
Anti-inflammatory nutrition - think greens, omega-3s, berries, fibre and protein with main meals
Daily movement - 30 minutes of cardiovascular exercise per day has been shown to reduce Alzheimer’s and dementia
Quality sleep - how much you need will depend on your DNA and your lifestyle
Stress management -yoga/stretching, breathwork, nature time, sunshine
Smart supplementation - No that doesn’t mean taking as much as you can, it mean’s a tailored approach and taking what you actually need based on facts and genetics.
Can all contribute to slowing — or even reversing — biological ageing.
In some studies, participants improved their biological age by over 2 years in just 8 weeks through nutrition and lifestyle changes alone (Fitzgerald et al., 2023).
Why This Matters
Unlike chronological age, biological age gives us a roadmap — a way to track how our lifestyle choices are impacting our long-term health. It helps us shift from just “feeling older” to understanding why, and more importantly, what to do about it.
It’s not about staying young forever. It’s about staying well — mentally sharp, physically strong, emotionally balanced — as the years go by.
Final Thoughts
You can’t control your birthday, but you can influence how you age.
Start by tuning in: How’s your sleep? Your energy? Your mood? Are you fueling your body or just getting through the day? Are you taking any medications for a disease that could be reversed through diet/and or lifestyle? How’s your performance and stamina? Do you get sick often?
It’s never too late to support your cells — one step at a time.
