BURN FAT, BALANCE HORMONES, BOOST ENERGY

8-WEEK GROUP PROGRAMME · JANUARY 2027 COHORT

Your body composition is not improving.
Your energy won’t increase.
There is a reason.

The In-Sync Metabolic Reset is an 8-week group programme with weekly live sessions, clear weekly milestones, and private measurement at the start and end — so you can see exactly what has changed. Not a diet. A whole-system recalibration that addresses diet, energy, hormones, movement and resilience.

Next cohort starts Monday 11th January 2027 · 6.30pm · Live on Zoom

What the eight weeks look like

A clear journey with a clear destination.

Each week has a specific focus and a specific milestone. You can see the full week-by-week curriculum on this page. Here is the shape of the journey.

Before you begin

Private baseline measurement

You measure your weight, waist-to-hip ratio, and hydration privately before the programme begins. These are your numbers — not shared with the group. They are the starting point everything is measured against.

Weeks 1–8

Weekly live Zoom sessions with weekly milestones

Every week has a specific focus — how you eat, how you drink, how you move, and the deep learning that makes the changes stick. Each session builds on the last. You know exactly where you are and what comes next.

Throughout

Group accountability

The group is not just company — it is one of the most powerful mechanisms for change available. Shared experience, shared progress, and knowing others are on the same journey in the same week keeps you moving when motivation alone would not.

At the end

Private end measurement

You measure again — privately — at the end of the eight weeks. Weight, waist-to-hip ratio, hydration. The numbers belong to you. What they show is the result of eight weeks of working with your body rather than against it.

What you walk away with

More energy, greater fat burning potential. The knowledge that you can.

By the end of eight weeks you will have shifted how your body burns fuel, increased your energy, and experienced what it feels like when your metabolism is working with you. More than that — you will understand your own body well enough to keep it that way.

WHY NOTHING HAS WORKED SO FAR

Your body has been doing exactly what it was designed to do.

Maybe your nervous system has been under sustained pressure, your metabolism has slowed down. Energy expenditure has changed, appetite and blood sugar regulation has shifted. Your body is more focused on conserving energy and maintaining stability than on losing weight.

The In-Sync Metabolic Reset works at this deeper level, looking at the interconnected systems that regulate metabolism, including the nervous system and hormonal system.

This is not just another diet. It is a whole-system metabolic reset designed to create lasting change.

Fleur Borrelli

Clinician. Researcher. Co-author.

Clinical Psychoneuroimmunologist · Nutritional Therapist · 20+ years clinical experience

Fleur Borrelli is a clinical psychoneuroimmunologist and nutritional therapist, one of a small number of practitioners working at this level in the UK. With over 20 years of clinical experience, her work sits at the intersection of neuroscience, immunology, endocrinology, and nutritional medicine.

Her path into this work began with a discovery about her father's wartime trauma and the way it had silently shaped her family's health for generations. What happens to us shows up in the body long after the event has passed.

Fleur is co-author of The In-Sync Diet with actress Glynis Barber, and the framework behind that book is the foundation this programme is built on.

  

 

WHAT PAST PARTICIPANTS SAY

Real change, week by week.

 

I noticed that I had lost weight around my waist and face and also on my thighs. My skin glows more and my finger nails are stronger. My sleep has improved and I sleep a little longer and definitely more deeply.

Sophie, London

Fleur has a lovely manner, it is very easy to talk to her. I think Fleur's approach stands out because it is a holistic approach — her nutritional advice is not purely for weight loss. A lot of Fleur's teaching is about eating towards better mental health as well as physical wellbeing.

Sam, Darlington

I have no doubt that Fleur's specialist approach has helped speed up my metabolism and improve my mood. The programme made me feel better in myself and the weight loss combined with the improved comfort levels after eating has given me confidence.

Leslie, Worthing
