Elena Juarez punched and food-prepped her way to losing 100 pounds. But her weight-loss journey kicked off with a serious health scare.

About a year ago, her 10-year-old daughter, Biani, arrived home with a school nurse’s recommendation for a diabetes test. “She came home crying, asking if she was going to die,” the 34-year-old businesswoman and mother of two tells Health. “I assured her she was fine but I was definitely concerned.”

One hundred lost pounds later, she credits going keto and sticking with kickboxing for her weight loss. “Even at my heaviest, I was always a healthy big girl,” she says. After visiting the doctor, “I didn’t know how to approach it, but I knew we all needed to change our unhealthy ways.”

Now, she does an hour-long workout that combines cardio and strength training four to five times per week. She also follows an intuitive eating regimen.

She is proud to say she hasn’t given up her favorite food: pizza.
