Entertainment TV Jazz Jennings Shares How She Lost 30 Lbs. Ahead of Gender Confirmation Surgery The 18-year-old transgender reality star says she had to "retrain" her mind to change her relationship with food By Aurelie Corinthios Published on February 5, 2019 04:04 PM Share Tweet Pin Email Before Jazz Jennings could be approved for gender confirmation surgery, she had to shed some serious pounds — and now, she’s revealing how she accomplished her goal. “I really had to just retrain my mind,” the 18-year-old transgender star of I Am Jazz on TLC tells PEOPLE Now of how she dropped 30 lbs. “I had to look at food as something different than what I was looking at it as,” she explains. “Because I used food as a comfort for my emotional struggles. I was a binge-eater. It was really bad. I would go to McDonald’s, get 20 chicken nuggets, three chocolate chip cookies and a large fries.” “I really had to stop doing that and realize that was so unhealthy and I need to take care of myself,” she adds.
