Tyler Baltierra is focusing on his health and fitness as wife Catelynn Lowell remains in treatment at an Arizona rehab center.

Months after Lowell went public with thoughts of suicide, Baltierra has his hands full as he attempts to maintain his home and raise his daughter, three-year-old Novalee Reign, with his wife continuing to treat her ongoing struggles with depression and anxiety.

While Baltierra has his hands quite full, he hasn't lost track of his own health, and for the past several weeks, he has been sharing regular updates with his fans and followers on Instagram in regard to his weight loss efforts.

In his most recent photo, Baltierra is seen posing shirtless for the camera as he tells his online audience, “AYYYYY!!! Feels so damn good reaching this weight loss goal!” #TOOLPIC.” According to a report by Us Weekly magazine, Baltierra shared the photo on Feb. 10.

Weeks ago, after showing off a before and after image of his weight loss, the Teen Mom OG dad opened up about his weight loss efforts, revealing that while he's not exactly following any diet in particular, he is definitely making a point to eat heathier.

“I just started caring more deeply about what I was putting in my body,” he tweeted last month. “To jumpstart the weight loss, I cut out carbs (besides toast in the a.m.) filled up on fruit, smoked fish, & vegetables for lunch & ate lean meats, vegetables & salad for dinner.”

As Baltierra does his best to stay healthy, he's also struggling with personal hardships due to his wife's absence. As he explained in a post to his fans and followers on Instagram last week, he has good days and bad days, and at times, he doesn't know what to say to his daughter, Nova, when she misses her mom. Baltierra went on to say that he shared his tearful Instagram post with his online audience in an effort to help others who may be feeling the same way.

“We’re humans, we’re allowed to have bad days, hard times & weak moments,” he added. “Don’t be ashamed of what makes us humans special. You’re loved. You’re worthy.”
