The 26-year-old Teen Mom OG star announced the news via Instagram and revealed his before-and-after shot.
"26lbs DOWN!!!" he wrote. "To be honest I didn't even want to take a before picture, because I was already thinking of me not sticking with it & then having the evidence of failure to look back on. But DAYYUMM dude! This got me feeling some type of way right now! Left picture was almost 5 weeks ago & right picture was today. Eating healthier just feels better & obviously looks better hahaha lol BOOM! #LifestyleChanges #Goals."
