Now she's opened up even more about the reason for her rapid weight loss after she did a Q&A on Instagram and a fan asked her: "Why so thin?"
In a long message posted to her Instagram story, Ariel explained that she had previously gained weight because of the antidepressants she was taking at the time.
For years I had been on anti-depressants that caused me to gain weight that I couldn't lose no matter what I did. It was always frustrating for me because I wanted to get fit and feel like the work I was doing was paying off, but it never felt that way. I had accepted it and moved on.
