The weight loss journey for Wilson actually began back in 2016.

That is when she revealed in an interview with Cosmopolitan that she had a hormonal imbalance that made her more prone to gaining weight.  

In other words, she was an emotional eater.  Food is a drug to her, and she is addicted.  

“I love me some ice cream or dessert, and it comes at times when I’m happy or sad. So when I have an incredibly stressful day, I want to celebrate and reward myself with food. If I’ve had a sad or stressful day, food is also comfort. You would probably describe it as emotional or stress-eating…eating is my one vice. I wouldn’t ever want to totally give it up.”
