The science behind easier weight loss

Sustainable weight loss depends on maintaining a calorie deficit, but hunger makes this difficult to maintain.
Hunger Guard works by mimicking the natural fullness created by food. Its ingredients absorb water and expand in the stomach, increasing physical volume and activating the body’s satiety response.


This helps you feel full sooner, stay full for longer, and naturally reduce calorie intake, making weight loss more achievable and sustainable over time.

The only EFSA-recognised fibre for weight loss

Glucomannan, a key ingredient in Hunger Guard, is officially recognised by the European Food Safety Authority (EFSA) for its contribution to weight loss when used alongside a calorie-controlled diet.
This clinically studied fibre absorbs water and expands in the stomach, mimicking the physical fullness created by food. This activates the body’s natural satiety response, helping you feel full sooner, stay full for longer, and naturally reduce calorie intake.

How Does It Work?

Hunger Guard™ contains two clinically studied, water-soluble dietary fibres: glucomannan from the konjac root (Amorphophallus konjac) and psyllium husk from the seed coat of Plantago ovata.
These fibres absorb water and expand in the stomach, forming a dense gel that mimics the physical fullness created by food. This gently stretches the stomach and activates the body’s natural satiety signals.
This process helps regulate appetite by supporting hormones involved in hunger and fullness, including ghrelin, peptide YY (PYY), and glucagon-like peptide-1 (GLP-1). Digestion slows, fullness lasts longer, and overall calorie intake naturally decreases.
By helping you feel satisfied with less food, this clinically studied mechanism supports sustainable, biologically driven weight loss.

The Scientific Researchers

The ingredients in Hunger Guard™ have been extensively studied by independent researchers and academic institutions specialising in nutrition, metabolism, and weight management. Peer-reviewed research has demonstrated that glucomannan and psyllium husk support satiety, appetite control, and weight loss when used alongside a calorie-controlled diet.

EFSA Scientific Opinion Confirming Glucomannan Contributes to Weight Loss

Published by the European Food Safety Authority (EFSA)
The European Food Safety Authority (EFSA) concluded that glucomannan contributes to weight loss when consumed daily alongside an energy-restricted diet. This conclusion was based on human clinical trials
demonstrating reduced body weight.

Effects of glucomannan supplementation on weight loss in overweight and obese adults: A systematic review and meta-analysis of randomized controlled trials

Published in Clinical Nutrition Open Science
This systematic review and meta-analysis of six randomised controlled trials involving 225 participants found that glucomannan supplementation resulted in a statistically significant reduction in body weight. Its ability to absorb water and expand in the stomach increases satiety and helps reduce energy intake, supporting its role in weight management.

Effect of glucomannan on obese patients: a clinical study

Published in Pubmed
This randomised controlled trial found that obese participants taking glucomannan lost an average of 5.5 lbs over 8 weeks, without changes to diet or exercise. This supports glucomannan’s role as an effective dietary fibre for supporting weight loss.

Psyllium is a natural nonfermented gel-forming fiber that is effective for weight loss: A comprehensive review and meta-analysis

Published by Procter & Gamble Co., Mason, Ohio
This clinical study found that psyllium supplementation significantly improved body weight, body composition, and metabolic health markers in overweight and obese participants. Psyllium’s ability to absorb water and expand in the digestive tract increases satiety and supports reduced energy intake, contributing to its effectiveness in weight management.
