"My weight won't shift no matter what I try"
Your metabolism isn't slow. It's protecting you.
In-Sync Metabolic Reset is an 8-week group programme for women that addresses the nervous system, hormones, and metabolism together so your body stops holding on to stored fat and starts responding.

Why nothing has worked so far
Your body has been doing exactly what it was designed to do. When the nervous system is under sustained pressure, and for many women that pressure has been building for years, sometimes decades, it activates a coordinated survival response across your whole body. Cortisol rises, insulin resistance follows, leptin signalling is disrupted and the immune system shifts into a state of low-grade chronic activation. Your metabolism doesn't slow down randomly. It downregulates deliberately, as part of an intelligent adaptive programme designed to protect you.
This is why calorie restriction doesn't work long term. This is why more exercise sometimes makes things worse. And this is why you can be doing everything right and still feel like nothing is shifting, because the intervention has to match the mechanism, and the mechanism is not what most programmes address.
The In-Sync Metabolic Reset works at the level of that original mechanism. Not the symptom.

Meet Your Guide
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. That understanding is at the heart of everything she does clinically.
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.

"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."

"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
