The Science & The Maynard Formula

Where neuroendocrinology meets real-world appetite control.

The Maynard Formula is built on advanced research in appetite regulation, metabolic signalling, and gut–brain communication, based on the work of Dr Juliana Maynard, PhD –Neuroendocrinologist.

Instead of relying on stimulants or simple fibre bulking, the Maynard Formula targets the multi-pathway biology of appetite – the same systems that influence hunger, fullness, cravings, mood and daily metabolic balance.

This is science designed to work with your biology, not against it.

How the Maynard Formula Works

A Multi-Pathway Approach to Appetite

The Maynard Formula supports the body’s natural appetite regulation across six key pathways:

Ghrelin & Hunger Modulation
Supports the body’s natural regulation of ghrelin – the primary hunger-signal hormone – to help reduce sudden spikes in appetite.
Satiety Hormone Support
Works with the pathways involved in fullness signalling, helping meals “register” more effectively so it’s easier to feel satisfied.
Gut–Brain Axis Signalling
Supports healthy communication between the gut and brain, helping reduce dysregulated cravings and chaotic hunger cues.
Fibre-Induced Fullness & Gastric Modulation
Uses fibre-linked mechanisms to gently slow gastric emptying and extend feelings of fullness after eating.
Neurotransmitter & Mood Balance
Supports neurotransmitter pathways that influence emotional eating, reward-seeking and stress-driven snacking.
Reward-Circuit Recalibration
Helps support healthier reward signalling in the brain, making it easier to move away from high-sugar, high-fat “quick fixes”.

How to Take Ghrelin-X®

Timed to Work With Your Natural Rhythms

Ghrelin-X® is designed as a simple daily routine:

One sachet 20–30 minutes before each main meal
Mix with water into a light blood-orange coloured drink
Enjoy as part of your pre-meal ritual

Taking Ghrelin-X® before meals aligns the Maynard Formula™ with your body’s natural hunger and satiety cycles, supporting appetite regulation before you start eating.

Why This Science Is Different

Built on Biology – Not on Needles or Stimulants

Unlike pharmaceutical GLP-1 drugs or stimulant-based products, the Maynard Formula™:

Does not use synthetic hormone analogues
Does not rely on caffeine or harsh stimulants
Works by supporting the body’s own appetite pathways rather than overriding them

This multi-pathway, research-led approach allows Ghrelin-X® to support:

Calmer, more predictable appetite
Better satiety after meals
Reduced cravings and emotional eating
More consistent day-to-day food choices

All in a format you can take safely and conveniently, every day.

From PhD Research to Everyday Use

The Maynard Formula is based on Dr Juliana Maynard’s PhD work in appetite regulation and obesity management, as well as ongoing research across diet, hormones, and neuroendocrine pathways.

Her goal – and Xentra Health’s – is simple:
to translate rigorous science into practical, accessible tools that help people take back control of appetite, food choices and daily wellbeing.
