Biological Age: Redefining What It Means to Get Older

Originally sent on 19 July 2025

Live on TV, I revealed someone’s biological age—and the curiosity was electric. People wanted to know: “How young am I really?” Because age on your passport tells one story; biological age tells another. Chronological age is just years on a calendar. Biological age measures how well your body is actually functioning. It moves forward and backward depending on stress, recovery, inflammation and lifestyle. And while you can’t change the date on your birth certificate, you can change your biological age.

DATA — Where insight becomes impact

We all want more time. Many people hope to appear younger when asked their age because they want more decades ahead. Feeling older than your actual age steals joy; it shows up as aches, poor sleep, fatigue and frustration. Biological age matters because it predicts disease, disability and death better than chronological age. The older your biological age, the higher your risk of disease—even if you’re young by calendar age. Biological age helps you see what’s working for you: Is your intense workout helping or harming? Are your veggies and smoothies making a difference? Are your habits ageing you faster than you think? The good news: you can test, track and change your biological age.

DEVICES — Track it to hack it

What do most people come to me for? Sharper focus, better sleep, more energy, weight control, reversing a diagnosis, coming off medications, lifting brain fog, banishing bloating, slowing ageing, looking younger and feeling younger. In clinic, everyone starts with the same thing: a biological age test. It’s a finger‑prick blood sample kit delivered to your home. You send off a small sample; we interpret your results and create a personalised plan. The test is simple yet seriously insightful: it’s precise, personal and predictive of your future healthspan. CEOs, athletes, parents and teenagers use it to reveal their real biological age and get a full breakdown of how their lifestyle, nutrition, stress and environment affect their health.

DECISIONS — From knowing to doing

The test itself is only the beginning. Once you know your number, you get personalised recommendations—things you need more of, things you need less of, things to stop and things to start. We look at markers like glycan age, inflammation markers, epigenetic tags, hormone levels and nutrient status. Your biological age doesn’t have to equal your chronological age. One client, a 42‑year‑old founder, discovered she was +11 years older biologically. Disrupted sleep, glucose highs, hidden pre‑diabetes and low‑grade inflammation were accelerating her age. We focused on restoring sleep, calibrating nutrition, regulating stress and reversing pre‑diabetes. After 10 weeks, her biological age dropped to 32.

DIARY — Where you’ll find me…

Last week: I was in the ITV studios with Cat and Ben, with messages pouring in from viewers after the show. This week: I hosted a special bioage reveal for a VIP couple and answered DMs about ageing younger. Next week: I’m on a mission to help more people know their real age and reverse it.

DISTINCTION — A thought to pause on…

Chronological age tells a story. Biological age writes it. By testing and tracking, you can change the plot.
