Eating a bowl of porridge in the morning can keep a person feeling fuller for longer according to scientists from King's College London.
Their study suggests that foods with a low glycaemic index (GI), like oats, trigger the release of greater amounts of a hormone in the gut, which delays hunger pangs by creating a 'full' sensation.
It is already known that a low GI diet takes longer to digest, releasing sugar more slowly into the bloodstream.
Now, King's College researchers have found that foods with a low GI score, which include brown bread and most fruit and vegetables, stimulate the release of around 20 per cent more of the GLP-1 hormone per meal than foods with a high GI ratio.
Study's lead author Dr Reza Norouzy said that the chemical was 'one of the most potent hormones for suppressing appetite'.
"Our results suggest that low GI meals lead to a feeling of fullness because of increased levels of GLP-1 in the bloodstream," the Telegraph quoted her, as saying.
"This is an exciting result which provides further clues about how our appetite is regulated, and offers an insight into how a low GI diet produces satiety," she added.
For the study, the researchers looked at the effects of different diets on 12 healthy volunteers.
The results of their findings were presented at the annual Society for Endocrinology BES meeting in Harrogate.
