On the eve of the COVID-19 lockdown, Roxanne Mullenberg weighed 358 pounds. By February 2020, she vowed to participate in a walking challenge with her colleagues. Though the country shut down weeks later, she had a new mindset to help her do right by her health - and lose 149 pounds. Lockdown had and continues to have numerous effects on people\u2019s physical and mental health. It impacted social availability and limited methods of physical activity. With the added stress from work and worrying over health, it was understandable when people felt demotivated. Mullenberg faced that and additional health hurdles to \u201cdo something\u201d for herself.

Mullenberg decided to join just in time for social isolation to become mandatory. Additionally, she had to figure out working from home while supporting her 11-year-old son Ryan in his home schooling. https:\/\/twitter.com\/LWeight411\/status\/1415228981985558531 RELATED: Flab To Fab: Some Of Our Favorite Artists Who Have Seriously Cut Down On The Pounds On top of all this, she also had an under-active thyroid, for which she was receiving medications, but required some time to find the right dosage. \u201cWhen my thyroid decided it didn\u2019t want to work correctly, that\u2019s probably when I started gaining more,\u201d she reflected. \u201cBut not realizing the reason why I was gaining either.\u201d Indeed, an under-active thyroid can make it difficult to lose weight. In the face of all this, though, Mullenberg actually found herself walking even more. She advocates for a change in attitude that helped keep her walking challenge going https:\/\/twitter.com\/goodlife\/status\/1410587703796711426 \u201cThe walks became such a good mental break and stress release,\u201d explained Mullenberg. \u201cIt became both a physical and mental benefit when I would do the walks, which was great. Then I\u2019d bring my child out and obviously we\u2019d both have these fun adventures roaming around parks.\u201d This continued routine in the face of daunting odds ended up just one manifestation of a bigger psychological strategy she exercised each day to keep making healthier choices for herself. She joined the eating program Profile by Sanford after some coworkers found success with it. At first, it called for leaning into eating shakes as main courses, before integrating grocery foods back in. As a result, Mullenberg, shared, \u201cI feel more like myself. I have more energy and I\u2019m getting confidence in myself again and overall feel like me.\u201d And all this, in part, is yet another branch of the greater tree of one resounding determination: changing her attitude. She admitted, \u201cI probably always cheated myself out of sticking things out before, not everything, but some things. Once I put my mind to something, I definitely can do it.\u201d And do it she did, and now has tips to share for everyone else whose health deserves their full attention: \tDo something for yourself. It\u2019s the ultimate form of self love. \tChange your mindset. Keep an open mind and think of diets as a way to get creative. \tSet doable, personal goals. No one glove fits everyone, so cater to your needs and abilities. How will you treat yourself coming out of quarantine?
