The Role of Blood Sugar in Cravings

By Dr. Juliana Maynard, PhD – Neuroendocrinologist

Cravings aren't always the same thing as hunger. What and when we eat can influence blood glucose, energy levels and our desire to eat again.

Foods high in rapidly absorbed carbohydrates can produce a relatively quick rise in blood glucose. The body's insulin response then helps move glucose from the bloodstream into cells. For some people, subsequent changes in glucose and energy levels may be accompanied by renewed hunger or a desire for something sweet.

Creating a steadier pattern

Meals containing protein, fibre and less rapidly digested carbohydrates generally take longer to digest and can help us feel satisfied for longer.

Simple habits can help:

• Include a source of protein with meals.
• Choose fibre-rich whole foods.
• Avoid relying on sugary snacks when genuinely hungry.
• Maintain a reasonably consistent meal pattern.

Blood glucose, however, is only one part of appetite regulation.

Hunger, fullness and cravings are influenced by an interconnected system involving the gut, brain, hormones, nutrients, sleep, mood and reward pathways.

This wider biological picture is important because appetite management isn't simply about avoiding sugar. It is about creating conditions that make hunger and satiety easier to manage.

GhrelinX® and the Maynard Formula® were developed around this broader, multi-pathway understanding of appetite regulation.

Food supplements should not be used as a substitute for a varied, balanced diet and healthy lifestyle.
