Gene that protects against obesity identified

Press Trust of India  |  London 

Scientists have identified a gene that could protect against obesity by increasing the feeling of fullness, a finding that may lead to potential new therapies to treat eating-related disorders.

Researchers from and Imperial College in the tested a high-fat diet, containing a fermentable carbohydrate, and a control diet on mice.



They looked at the effect on food intake of those with and without the FFAR2 receptor, a protein coding gene.

The showed that mice fed the diet containing fermentable carbohydrate were protected against obesity. However, this protection was lost when the FFAR2 receptor was not present.

Indeed, those with the receptor showed an increase of 130 per cent in the satiety inducing gut hormone peptide YY, as well as an increased density of cells containing PYY, leading to an increased feeling of fullness.

"Obesity is currently one of the most serious global threats to human health, determined by genetic background, diet and lifestyle," said lead author Gavin Bewick from King's College.

"We know that supplementing your diet with non-digestible carbohydrates reduce appetite and body weight gain, but in this study we demonstrate for the first time the essential role of the FFAR2 receptor in enabling specific dietary constituents to reduce food intake and protect against obesity," said Bewick.

"With this discovery, we can start to look at whether we can use diet or pharmaceutical means to change the cellular make-up of the gut in order to treat a host of disorders," he said.

"This a major step forward in understanding the relationship between diet and appetite regulation. Until a few years ago dietary fibre was a thought of as inert, and having very little effect on physiology," said Gary Frost from Imperial College.

So the fact it actually has a major impact on cells that help control appetite regulation in the colon is amazing," Frost said.

"Our challenge now is to translate this into a technology that we can apply to humans. We need to understand how we can use the knowledge and insight gained to develop food systems that are attractive to a large percentage of the population," he added.

The study appears in the journal Nature Reviews Endocrinology.

Gene that protects against obesity identified

Scientists have identified a gene that could protect against obesity by increasing the feeling of fullness, a finding that may lead to potential new therapies to treat eating-related disorders.
