Olivia Tilini was inspired to lose 55 pounds after she went to her doctor for a routine checkup.
At the time, she weighed 225 pounds and was a junior in high school. She’s 5-foot-10.
“He said I was overweight, and if I continued with my eating habits, I would eventually develop diabetes and need to take insulin,” says Tilini, 18, who is now studying public health at Brigham Young University in Provo, Utah. “I didn’t want to stick myself with a needle.”
So the summer after her junior year, when she was 16, Tilini focused on losing weight. She walked 4 to 8 miles every morning with her mother and played racquetball in the evenings with her family. She also did the Insanity DVDs, a high-intensity workout program.
