Staying thin and avoiding obesity could be helped by genes, study finds

If you diet and hit the gym regularly but are not seeing the results you hope for, it could be down to your genes.

In a new study, thin people were shown to have specific gene regions in their DNA keeping them slim, while also having fewer gene variants that have been linked to being overweight.

“We’ve found that there are genes associated with thinness,” said Sadaf Farooqi, professor of metabolism and medicine at Cambridge University, who led the study.

In the study, published Thursday in the journal PLOS Genetics, different genetic variants were added up to create a genetic risk score, which was found to be lower in thin people and higher in obese people.
