SAN DIEGO (CBS 8) - British researchers say they've discovered a gene that can determine if someone will become overweight.
Scientists at Oxford University call the gene KLF-14. They say it acts as a master "on-off" switch, directing other genes that control body fat.
KLF-14 is inherited from a person's mother.
Doctors say if they can find a way to control it, they might be able to treat obesity, heart disease, and diabetes.
