WASHINGTON (AP) — Nicole Ari Parker was motivated by frustration. For Star Jones, it was a matter of life or death. Toni Carey wanted a fresh start after a bad breakup.

African-American women have the highest obesity rate of any group of Americans. Four out of five black women have a body mass index above 25 percent, the threshold for being overweight or obese, according to the Centers for Disease Control and Prevention. By comparison, nearly two-thirds of Americans overall are in this category, the CDC said.
