About this work
What performance nutrition with Nicky Anstey actually involves
Performance nutrition with Nicky Anstey is one to one work for senior leaders, business owners and high performers whose mental performance suffers when nutrition slips. Nicky is a Registered Nutritionist aligned with medicine working with people whose load is cognitive rather than athletic. The aim is stable focus across long days, sustained energy, and a brain that holds up when the day gets hard, addressed alongside the wider Rewire Method.
This page sits in the wider nutrition cluster and is the right entry point if performance and energy are your primary concern.
What happens to leadership performance when nutrition is not part of the picture
Coffee in the morning, skipped lunch, late dinner, wine to wind down, repeat
Most senior leaders eat for convenience, not for performance. Each individual choice looks fine. The cumulative effect on focus, decision-making and recovery is significant.
Bad afternoon energy. Decision fatigue by 4pm. Sleep that takes longer to come and does not refresh. Brain fog that you have started to attribute to age. Nutrition does not fix everything. But ignored, it sets a ceiling on every other intervention you might be making, including the pattern-level work in Rewire Coaching.
How the work moves
Performance Nutrition for Senior Leaders Under Cognitive Load
The work is practical, evidence-based and built around the working life you actually have. We do not move you onto a diet plan you will not follow.
We map the day you actually live (meal timing, food choices, hydration, caffeine, alcohol, sleep) and work on the changes that produce the biggest cognitive return for the smallest disruption. Nicky’s training is in nutrition aligned with medicine, so where conditions like blood sugar regulation, gut health or hormonal balance are part of the picture, the work treats them properly.
What this work tends to shift:
- Afternoon energy crashes.
- Decision fatigue late in the day.
- Brain fog that has crept in over years.
- Sleep onset and sleep quality.
- Recovery from cognitive load.
- Reliance on caffeine to function.
- Alcohol as the wind-down mechanism.

Why Nicky
Why Work With Nicky Anstey
She has lived it. Nicky experienced severe burnout during her own corporate career, then built her businesses through significant personal and health challenges. The story is not background. It is the reason the work goes deeper than most coaching.
She has the qualifications to go deep. Nicky is a qualified Executive Psychotherapist, Master NLP Coach, Master Hypnotherapist, Master Life and Business Coach, and a Registered Nutritionist aligned with medicine. Five disciplines inside one practitioner. Most coaches hold one.
She has the results. Over 1,000 clients have worked with Nicky and gone through the trademarked Rewire Method. Reduced pressure, clearer thinking, stronger leadership, healthier lives.
She is not a generalist. Nicky works specifically with high-achieving business owners and senior leaders. The people who others assume are fine, because they are still performing. Read more about Nicky here.
Frequently Asked Questions
-
Is this a diet plan
No. The work is built around your actual life and the changes that produce the biggest cognitive return for the smallest disruption.
-
Will I have to give up coffee or alcohol
Not necessarily. The work usually focuses on timing, dosing and context rather than blanket elimination.
-
Do you do supplements
Where they are evidence-based and useful, yes. No supplement protocols pushed for the sake of it, and Nicky does not sell them.
-
I have a medical condition, can I still work with Nicky
In most cases yes, alongside your medical care. The Reset Call confirms.
-
How quickly will I notice changes
Most clients feel a difference in afternoon energy and sleep within two to three weeks.
