This pilot human study is investigating the potential of key nutrients, taken in capsule form, to act as appetite suppressants by targeting specific hormones found in the gut.

If you're aged 18 - 75, are overweight or obese but free from any other bowel condition you may be eligible for this study. Contact [email protected] for further details.

The study is recruiting 20 volunteers over two phases for this study, each of whom will participate in a double-blind, placebo controlled study.

The researchers are investigating the effect of the formulations on the metabolic rates of the participants. They are looking at data provided through questionnaires, the regular measurement of gut hormones and other biological indicators, and assessing the affect on appetite. If the study is successful a further study with an aim to help participants achieve weight loss is planned.

We are actively seeking healthy overweight volunteers. The study is being run from Queen Mary University of London so living in reasonable proximity from London, specifically East London, Essex and Kent may be an advantage. Download the invitation for further details.

This study is the result of work funded by Bowel & Cancer Research through the National Bowel Research Centre's human tissue laboratory.

The research team

The study is being led by Dr Madusha Peiris at the Wingate Institute for Neurogastroenterology, Queen Mary University, London.

Why a decoy bypass study?

Obesity is a major risk factor for bowel cancer; in fact it the key risk factor for many cancers after smoking. Recent evidence suggests that up to half of bowel cancers are related to obesity, particularly when the weight is carried around the waist.

Key facts 2016/17:
There were 617,000 admission where obesity was a factor (primary or secondary diagnosis)
26% of adults were classified as obese (not just overweight)
25% of year 6 children (10-11) were classified as obese and 10% of reception aged children (4-5)

It is often suggested that overeating is a lifestyle choice, but there is now evidence to support the fact that it is linked to a clear physiological disorder in many people and that these individuals produce low levels of important appetite controlling hormones.

The current best treatment is bariatric (gastric bypass) surgery. This is expensive and only available in a minority of cases when the individual's health is severely compromised. It costs up to £15,000 per patient.

Finally, with a rising population of overweight individuals (around 62% of UK adults and 33% of children), the indirect cost of dealing with obesity to the NHS is estimated to be in the region of £27billion which is unsustainable.

We are very grateful to the trustees of the JP Moulton Charitable Foundation whose support has made this research possible.
