TRENTON, N.J. (AP) -- A doctor who performs the type of surgery that New Jersey Gov. Chris Christie underwent says it "works nicely" to help people lose weight -- as long as you "eat appropriately and chew your food."
Dr. Christina Li is a bariatric doctor at Sinai Hospital of Baltimore. She says Christie is in a good position to benefit from the surgery, because he has the resources to have people help him eat right and get exercise.
She says the band that was placed around Christie's stomach to restrict the amount of food he can eat is removable -- but that patients are told to adjust to having it for the rest of their lives.
Christie secretly underwent the weight-loss surgery in February. A spokesman says the Republican governor agreed to the surgery after turning 50 in September -- but that he was motivated by concern for his family, and not by thoughts of running for president in 2016.
Christie has never disclosed his weight, but it's been an issue throughout his political career.
Dr. Jaime Ponce, who heads an organization of doctors who perform the surgery, says people who have the procedure can often lose 1 to 2 pounds a week.
