Helping people in midlife build energy, resilience and metabolic health to perform well and stay well for longer.

Midlife is often the most demanding time of life, and it's when daily habits shape how well the years ahead feel.

This is the decade that sets up the next thirty. Let's make them count.

The problem

Maybe you know something's off. Maybe you just want to stay ahead of it.

​

The morning tiredness that sleep doesn't fix.

The stress that never quite switches off.

The recovery that never comes.

The energy dips by mid afternoon.

The weight that won't shift.

The gut that never quite settles.

The focus that slips.

​

Your blood work says you're fine, or the numbers have started to creep. 

Either way, your body's telling you something.

​

There's usually a reason.

​

Finding it starts with your body's daily rhythm. That's my approach, Body Clock Nutrition, and it helps you rebuild your energy and feel like you again.

The health investigation

STV0824.SB.179.jpg

Together we look at what's shaping your energy and long-term health, then build a plan that works inside your real life.

​

The investigation maps:

  • Your rhythm: how you actually live, including when you see day light, when you eat, when you sleep, and how stress shows up across your day

  • Your biology: a review of any recent tests you've had done, plus targeted testing where it's useful, across energy, metabolism, stress, hormones, nutrients, and gut health

  • Your whole self: where science meets your life, your work and what matters most to you

​

The result is a clearer picture of what your body is doing and why, so that you can build the health that lasts.

My specialist areas: energy and performance · metabolic and heart health · stress and resilience · sleep and recovery

Tiredness is rarely just tiredness. In your 40s and 50s especially, it's often the first sign that your metabolic resilience is starting to slip. That's your body's capacity to make energy, handle stress and recover.

​

Your body runs on a 24-hour clock, set by daylight, darkness and when you eat. When it drifts, your whole body feels it: your energy, your metabolism, your stress response and your sleep.

​

My clinical approach, Body Clock Nutrition, starts with your daily rhythm, then moves through sleep and recovery, stress regulation and nourishment. Alongside this, I look at your wider biology, using blood and other tests where appropriate, so everything we do is targeted to you.

​

Before retraining as a nutritional therapist, I spent 15 years in senior strategic marketing, agency-side and client-side, with brands including Diageo and Unilever. I know the pace and pressure of a demanding working life, because I've lived a version of it.

​

Now I work with women and men in midlife, one-to-one, through workshops and talks, and with organisations, helping them build energy and resilience to feel well for longer.

​

I've worked with organisations including Nuffield Health, Corrigan UK, Agency UK, RPM, Initials CX, Helm Club and The Ned, and spoken at Happy Place Festival, Do Lectures, Cheltenham Literature Festival, Big Retreat and Abergavenny Food Festival.
