Chet Hanks, son of Tom Hanks and Rita Wilson, has made a significant transformation of his physique and mental health.

Falling into drugs and alcohol at 16, he later sought help and converted to Christianity, focusing on his health.

Recently, he shared a before-and-after selfie on Instagram showcasing his progress and encouraging fans to live healthily.

He contrasted his current 32, sober, 220lbs self to his 24, drug-using, 160lbs past.

Hanks mentioned the challenge of gaining muscle due to his ectomorph body type, meaning he has a high metabolism.

He credits his transformation to substituting substance abuse with training and a proper diet, which changed his mindset.

He encourages fans to do whatever it takes to match their visions of themselves, stressing that diet is key.

Hanks faced mixed reactions from fans, with some questioning if he was using steroids.

He previously revealed that his parents sent him to a wilderness program for troubled teens in 2008 when his addiction began.

Despite the challenges, Hanks says he found God and peace during that program and continues to radiate positivity to his community.
