Everyone knows that a diet high in sugar and bad fats may lead to obesity. But what they may not know is that an unhealthy Western diet is actually causing obesity on the genetic level. A new study published by the Federation of American Societies for Experimental Biology (online at the FASEB Journal) reports that eating a high fat, high sugar diet actually turns on genes that cause the body to store more fat than it needs.
From the press release, “In the research report, scientists show that foods high in fat and sugar stimulate a known opioid receptor, called the kappa opioid receptor, which plays a role in fat metabolism. When this receptor is stimulated, it causes our bodies to hold on to far more fat than our bodies would do otherwise.”
The research was done on two different groups of mice — one group who had had their kappa opioid receptor artificially deactivated and the other group unaltered. Both groups were fed an energy-dense, high-sugar, high-fat diet for 16 weeks. What the researchers found was that, while the mice with the unaltered receptor became obese, those with the altered receptor remained lean.
