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.

How Ghrelin-X works with your body
-
Appetite Regulation
Support fullness and appetite control
Hunger is influenced by hormonal signals that communicate between your gut and brain. Ghrelin, often referred to as the “hunger hormone,” plays a central role in initiating appetite and regulating food intake. Ghrelin-X is formulated to support satiety and help manage hunger signals throughout the day.
-
Craving Stabilisation
Help reduce cravings and support balance
Appetite isn’t driven by physical hunger alone. Mood, stress, reward pathways, and behavioural triggers can all influence cravings and eating patterns. Ghrelin is closely connected to brain regions involved in reward and motivation, linking appetite with emotional and behavioural responses.
-
Metabolic support
Support energy balance and metabolic function
The body’s metabolic system is regulated through a network of hormonal and neurological pathways that influence how energy is used, stored, and maintained. The gut–brain axis helps coordinate these signals to support appetite regulation and overall metabolic balance.
The gut–brain connection
Your appetite is regulated by a communication network between the digestive system and the brain known as the gut–brain axis. Hormones released in the gut send signals through neural and hormonal pathways that influence hunger, fullness, cravings, and energy regulation.
Ghrelin is one of the key hormones involved in this process. Produced primarily in the stomach, ghrelin signals the brain when the body anticipates food intake and helps regulate appetite and energy balance. Ghrelin levels naturally rise before meals and decrease after eating.
