This woman is out to prove that size really doesn't matter.

Once fit, Whitney Thore gained 200 pounds after contracting polycystic ovary syndrome.

After battling her weight gain, Thore ultimately decided it was okay to love her body the way it is and launched the No Body Shame initiative.

She also danced in this video to help others who may be battling weight problems and show it's okay to accept yourself as you are.
