In his immediate grief over the death of his mom, Ross Mathews said, "After mom died, I really found comfort in what I called 'grief pizza,' which is like unlimited pizza," per Today. He was also accustomed to late-night snacking. Eventually, he realized that wasn't the healthiest way to be and he decided to change his behavior. However, he didn't turn to a trendy diet or quick fix, he taught himself about food and healthier eating.

"It was about cutting out snacking," he said via Today. "Or if I did, I would snack on like a pickle or something. I was looking for the crunch. It was about replacing some things and really just knowing that if nothing changed, nothing changed. That if I didn't make some changes, I would be stuck in the same unhealthy place that I was."

In November, Mathews posted a photo of his dramatic weight loss on his Instagram and captioned it, "Breaking the pattern. 50lbs down today from my height in early June when I decided to reclaim my health after my mom died (70lbs down from my all-time). I will always be a work in progress. I may mess up again. I dunno. All I know is that I'm very grateful. And very happy. On we go..."

Mathews also mentioned that he recently moved to New York City and is walking more, which aided in his weight loss.
