Genetic switch may dictate if you crave more high-fat or high-sugar foods

We all love eating junk food even though we know it’s not part of a healthy diet…Now a team of researchers may have discovered a gene that acts as a switch, dictating whether we like high-fat or high-sugar foods more.

[S]cientists at the University of Cambridge found that neuronal pathways involving the melanocortin-4 receptor (MC4R) in the brain play a critical role in influencing food choice.

Previous studies in mice had shown that gene mutations that disrupted the MC4R pathway resulted in the mice eating a lot more fat. But when these mice were presented with sweetened food and water, they didn’t like those options and ate a lot less.

The results are exciting because they are the first to point to a genetic preference for certain kinds of foods, says Claudia Doege, who studies obesity at Columbia University. โ€œWe know that 40 to 60 percent of obesity is inherited but it has been very difficult to find which genes drives these cases,โ€ she said.
