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.
“Genes play at least 40% of a role in people’s weight,” Farooqi told CNN. “It’s much more than people realize.”
By adding up the over 100 different genetic variants the team came up with a genetic risk score and found that obese people had a larger genetic risk score than normal weight or thin people, which is not surprising, said Farooqi.On the other hand, this risk score was “very low in thin people,” so they have much less of the genes that contribute to people being overweight, compared to the rest of the population she explained. “They dodged a bullet.”
