How To Reverse Your Biological Age In Just 3 Months

Reverse your biological age in just 3 months: a step-by-step plan for men

A geneticist reveals the new science of ageing in reverse. Discover what you can do today to turn back your biological age

MOST MEN ACCEPT that feeling slower, weaker and more tired is just part of getting older. But emerging evidence suggests you can reclaim years of cellular vitality in as little as three months.

The results of a published pilot study which I led suggest that by targeting key drivers of ageing: mitochondrial health, oxidative stress and epigenetics (how your lifestyle impacts the way your genes work), men can measurably shift the trajectory of how they age[i].

Bridging the Male Health Gap

While Australian men are living longer than ever, they often spend their final decade of life in poor health[ii]. Globally, men’s average healthspan or years spent in good health lags lifespan by about nine years[iii]. With Australia’s over-65 population set to more than double in the next 40 years, bridging that gap is critical[iv].

The good news: with a focused plan, you can support strength, energy and mental clarity well into midlife and beyond.

Fuel Your Cells, Fuel Your Life

Mitochondria are the “powerhouses” in every cell, producing the energy molecule ATP[v]. They are most concentrated in energy-hungry tissues such as the heart, brain, muscles and even sperm[vi]. Ubiquinol sits at the heart of this process, supporting energy production[vii] and acting as a potent antioxidant[viii].

After the age of 30, our natural levels of Ubiquinol start to decline[ix]. Lower levels can impact energy[x], recovery[xi] and overall vitality[xii]. This makes maintaining mitochondrial health through strength training, restorative sleep, stress management and a nutrient-rich diet, key.

More Than Just Energy

Research shows that Ubiquinol’s antioxidant activity and role in cellular energy production can also support:

  • Heart health: Helping maintain healthy cholesterol levels and normal cardiovascular function[xiii].
  • Exercise recovery: Assisting with muscle recovery after intense workouts and relieving tiredness or fatigue[xiv].
  • Male fertility: Supporting healthy sperm count, motility and morphology[xv].
  • Healthy ageing: Helping to neutralise free radicals and reduce oxidative stress, a key driver of accelerated ageing[xvi].

These benefits complement the exercise, diet and mindfulness practices that form the backbone of the three-month plan.

A Three-Month Blueprint to Turn Back Your Biological Age

Month 1: Build Your Base

  • Exercise: 30 minutes daily and three strength sessions weekly. Start with bodyweight exercises.
  • Nutrition: include daily:1.6-2 grams protein/kg ideal weight, six serves of vegetables (greens, cruciferous, colourful), whole grains and fresh herbs and spices.
  • Hydration: Water, herbal teas, maximum 2 coffees (before 2pm).
  • Mindset: 5-10 minutes meditation or breathwork daily.

Month 2: Add Resilience

  • Training: Progress to using weights and include compound movements like squats and presses.
  • Cold Exposure (optional): Experiment with a 30–60 second cold shower which is good for building mental resilience (avoid if you have stress/immune issues).
  • Wholefoods: Ditch processed foods; add nuts, seeds, omega-3s and fermented foods.
  • Track: Monitor your workouts, sleep and energy.

Month 3: Lock It In

  • Prioritise recovery: Consistent, high-quality sleep (recommendation 7-9 hours per night) is essential for mitochondrial function.
  • Nutrition: Stick to protein and diverse vegetables; swap refined carbohydrates for complex ones.
  • Consistency: Aim for 80% adherence – sustainable wins beat perfection. The payoff is building habits that stick long beyond three months.

Strong at Any Age

Healthy ageing isn’t just about avoiding illness. It’s about preserving the vitality of your cells so you can stay strong, energised and resilient at every stage of life.

In fact, our pilot study looked at a range of biological age measures and found meaningful improvements. Markers of cellular and DNA damage, key drivers of accelerated ageing, were significantly reduced. The PhenoAge clock, which reflects metabolic health and blood biomarkers, also showed a measurable improvement.

And while we can’t rewind the calendar on our birthdays, we can turn back our biological age – the age of our cells – in as little as three months. The tools are simple but powerful: real, nutrient-rich food, regular exercise and incorporating targeted compounds that support mitochondrial and cellular health.

With the right plan, it’s possible not just to add years to life, but life to years.
