In this clip from a recent episode of "Our America with Lisa Ling," Lisa investigates the childhood obesity epidemic.

One mother, Stacie, has trouble saying no to her 4-year-old son, Jaylen, who now weighs more than twice the recommended weight for a child his age. Stacie seeks help from medical specialists, who hope to get 101-pound Jaylen on track to a healthy lifestyle.

"I'm angry at myself because I let it get out of control," Stacie says. "Jaylen is my baby and I love him.... And I want him healthy. And I'm willing to do any and everything to see that happen. I don't want to hurt him any more than I already have."

"Our America with Lisa Ling" airs Tuesdays at 10 p.m. ET on OWN.
