Miller in 2016

In 2016, Miller responded to criticism over his weight gain by sharing his personal struggles. After The LAD Bible posted a now-deleted meme that fat-shamed him, he addressed the issue by revealing his past battles with suicidal thoughts in a since-deleted Facebook post.

Miller revealed that photos of his weight gain in 2010 were taken during the “lowest point in my adult life,” when he turned to food for comfort while struggling with his mental health.
